Description

  The present invention uses the hypersonic sound, which has a non-stationary structure that contains abundantly high-frequency components exceeding the upper limit of human audible frequencies, to the brainstem, thalamus, and hypothalamus, which are the parts responsible for the basic functions of the brain. To increase the regional cerebral blood flow of the fundamental brain including and the fundamental brain network that projects into the brain based on the fundamental brain (hereinafter, these are collectively referred to as the fundamental brain network system) and activate these regions The present invention relates to a portable electronic device for generating vibrations that can lead to an effect of comprehensively enhancing mental activity and physical activity (hereinafter referred to as hypersonic effect). In other words, the present invention specifically increases the electroencephalogram α-wave power, enhances the aesthetic sensitivity to general sensory input, including accepting sounds pleasantly and beautifully, and thereby the sensitivity of complex sensory information including sound. Intensify the effect and strengthen the listening behavior, and reduce stress and fundamental brain activity by optimizing the activities of the emotional system, behavior control system, autonomic nervous system, endocrine system and immune system based on the fundamental brain Metabolic syndromes such as hypertension, hyperlipidemia, diabetes, cancer, cerebrovascular disorders, heart disease, immune disorders including hay fever and atopic dermatitis Various mental illnesses such as lifestyle-related diseases, depression, schizophrenia, dementia, chronic fatigue syndrome, attention deficit hyperactivity disorder, suicide / self-injury, abnormal aggression It relates to a portable electronic device for generating vibrations can lead the effect of overall improvement and abnormal behavior such.

  The inventors of the present invention have developed a hypersonic sound, which is a sound having an unsteady structure rich in super high frequency components exceeding the upper limit of the audible frequency, and a basic brain including a human brain stem, thalamus and hypothalamus, The core brain activation effect of increasing the brain wave α wave power, which is an indicator of core brain activity, while increasing the regional cerebral blood flow of the core brain network (basic brain network system) projected into the brain based on the core brain Guides, enhances aesthetic sensitivity, including accepting sounds pleasantly and emotionally, strengthening listening behavior, reducing stress, optimizing autonomic nervous system, endocrine and immune system activities, and improving mental and physical conditions Comparing with the improvement effect, that is, the hypersonic effect, when listening to the sound that does not contain the super-high frequency component, compared with the background noise state It found that reducing the activity of the fundamental brain (e.g., see Patent Documents 1-4 and Non-Patent Documents 1 and 2).

  In addition, the present inventors have so far complicated the natural environmental sound of the rainforest, which is the most promising environment in which human genes have evolved, by far exceeding the human audible frequency upper limit of 20 kHz. The environment sounds of cities where modern people live contain almost all of these ultra-high frequency components, whereas the structure has a structure that changes to a high level and can contain the fundamental brain activation effect. It has been clarified that the activity of the fundamental brain is reduced (see, for example, Patent Document 5 and Non-Patent Documents 3 to 4).

  The fundamental brain activated by hypersonic sound is an important base for neural circuits such as the monoamine nervous system and opioid nervous system that are closely related to the control of human emotions and behaviors. Therefore, it is known that abnormal activity of the neural network projected from the basic brain and from there to the entire brain leads to various mental and behavioral abnormalities. The fundamental brain is also the highest center of the autonomic nervous system and endocrine system, and controls the immune system through them, and plays a role in maintaining systemic homeostasis and the body defense function through these. Therefore, abnormalities in the activity of the fundamental brain are closely related to the onset of lifestyle-related diseases that are rapidly increasing in modern society by leading to the breakdown of the homeostasis maintenance function and the biological defense function.

  Therefore, when focusing on the specific and rapid increase in mental and behavioral abnormalities and lifestyle-related diseases such as those mentioned above, one of the causes is the sound environment surrounding modern people. A major departure from the specific acoustic structure that characterizes the environmental sound of the rainforests, which are the most promising candidates for the evolutionary environment of genes, and the lack of super-high frequency components that change in particular. There is a high possibility that the activity of is abnormal.

  On the other hand, reproducing the natural environment of a rainforest as it is in a modern city is an urgent issue of the above problems facing modern society, both in terms of climate and biological conditions, and in terms of the amount of time and social investment required. It is not a realistic solution that fits the nature. Therefore, using a vibration signal with a specific structure that leads to the fundamental brain activation effect and a vibration generator that can generate it as vibration, just like rainforest environmental sound adapted to human gene design A method has been proposed to generate the fundamental brain activation effect by generating vibrations that lead to the fundamental brain activation effect and presenting it to the modern person, and solve the above-mentioned mental and physical health problems faced by the modern person. (For example, refer to Patent Document 5).

  However, audio signals in a digital format that are recorded on a solid memory and output by a portable player, broadcast / communication, etc., which are acoustic information media widely used in modern society, such as compact disc (CD), mini disc (MD) Most of the audio signals in digital format distributed / distributed via the radio cannot record / reproduce super-high frequency components, and therefore cannot generate hypersonic sound and activate the basic brain.

  On the other hand, in recent years, formats such as Super Audio CD (SACD), DVD Audio, Blu-ray Disc (BD) soundtrack, and network distribution by high-speed optical communication, etc., have a format that allows recording, transmission and playback up to a band that greatly exceeds the upper limit of the audible range. Digital media is becoming available. However, in these cases, because the vibration generation function of the sound source and the performance limit of the recording / editing device, etc., the vibration signal recorded on the recording medium, that is, the content does not contain the super-high frequency component.・ It is customary that sound cannot be generated and the fundamental brain activation effect cannot be induced.

  Furthermore, when presenting the listener with an audible range component that is an oscillating component in the audible frequency range, an artificial signal such as white noise is sufficiently included in the listener. However, it has been found that the hypersonic effect does not appear (for example, see Non-Patent Document 2). Further, a hypersonic component such as a sine wave-like signal having a peak at a specific frequency and its overtone, and quantization noise associated with a high-speed sampling 1-bit quantization method does not exhibit a hypersonic effect. Furthermore, in recent years, ultra-high frequency components consisting of sinusoidal signals with peaks at specific frequencies generated from artifacts such as electronic devices have been negatively affected by humans and animals presenting them, such as discomfort and escape behavior. It has been found to lead to the effects of the above, and is used as a youth protection device, a repelling device, etc. (see, for example, non-patent documents 5 to 6).

  These findings suggest that in order to induce the fundamental brain activation effect by the hypersonic effect, it is not necessary to simply present the ultra-high frequency components exceeding the upper limit of the audible range, and these ultra-high frequency components have some specific structure. This suggests that the vibrations of ultra-high frequency components with a unique structure that is different from the above may have a risk of negatively affecting the physiological state of humans and animals. Yes. However, the structural features that should be provided with the ultra-high frequency component of vibration that can lead to the fundamental brain activation effect have not been clarified so far. Therefore, even if a digital format capable of recording / reproducing super-high frequency components such as a super audio CD (SACD) or Blu-ray disc (BD) sound track, or network distribution using high-speed optical communication is available, It is unclear what structural features the vibration signal recorded and transmitted there will lead to the fundamental brain activation effect.

  First of all, since the structural features of the ultra-high frequency component that can lead to the fundamental brain activation effect have not been specified, the ultra-high frequency component artificially synthesized from white noise etc. As seen in the example that does not lead to an effect, even if the sound presented to the listener contains an ultra-high frequency component, whether the vibration signal actually leads to the fundamental brain activation effect of the listener is determined. There is a problem that it cannot be estimated from the structure itself. In other words, whether or not a certain vibration leads to the fundamental brain activation effect is shown to the listener each time, and the fundamental brain activity of the listener is measured by an advanced brain function measuring means such as a positron tomography device or an electroencephalograph. It is necessary to actually observe whether or not the basic brain is activated by measuring it through rigorous physiological experiments using. The reality is that the method of measuring the fundamental brain activity for all vibrations and measuring the fundamental brain activity before linking it to practical use is not realistic. Therefore, in order to estimate whether a specific vibration can lead to the fundamental brain activation effect without conducting physiological experiments, the structural features of the vibration signal that can lead to the fundamental brain activation effect Need to be identified.

  Secondly, since structural features of the super-high frequency component that can lead to the fundamental brain activation effect have not been specified in the past, vibrations containing the super-high frequency component that can lead to the fundamental brain activation effect are artificially generated. There is a problem that it cannot be synthesized. In particular, considering that it has become clear that certain artificial ultra-high frequency components have a negative safety effect on the physiological state of humans and animals, Vibrations that can lead to vibrations generated from specific natural and natural vibration sources, such as rainforest environmental sounds and certain folk instrument sounds, which have proven their effectiveness and safety Will be recorded and used. However, the types and amounts of natural and natural vibration sources that can lead to these fundamental brain activation effects are limited, and their collection and recording is often accompanied by great difficulty and sometimes even danger. Therefore, in order to artificially synthesize various types of vibrations that can induce the fundamental brain activation effect without relying on limited natural natural vibration sources, the fundamental brain activation effect is derived. The structural features of vibration that can be identified need to be identified.

  Thirdly, despite the fact that various band expansion methods have been proposed as a way to compensate for the high-frequency component for the vibration signal lacking the super-high-frequency component, the fundamental brain activation effect is derived. Since the structural features of the super-high frequency component that could be used have not been specified in the past, whether the super-high-frequency component artificially stretched by the conventional band stretching method leads to the fundamental brain activation effect In order to confirm, there is a problem in that it is necessary to carry out a physiological experiment each time and confirm each vibration. In particular, as mentioned above, in consideration of the fact that some artificially synthesized ultra-high frequency components do not exhibit the hypersonic effect or conversely have negative effects reported, The importance of determining whether the structure of the ultra-high frequency component artificially stretched by the band stretching method can lead to the fundamental brain activation effect, that is, whether it is effective and safe for humans Is extremely expensive.

  Fourth, due to the existence of such a wide variety of problems, the vibration generated by the vibration sources and vibration generators of the vast number of existing recording libraries cannot lead to the fundamental brain activation effect, and the sensuous artistic value. There is a problem that it is not only severely impaired, but rather induces various modern diseases by lowering the basic brain activity and has a high risk of seriously threatening the comfort and safety of modern people. There is a demand for technology that overcomes these limitations and prevents danger.

  Fifth, distribution and distribution using audiovisual content recorded on high-capacity package media such as DVDs and Blu-ray discs, which are rapidly spreading in recent years, and high-speed and large-capacity communication lines such as high-definition television and high-speed optical communication In the content that works on multiple sensory systems such as visual and auditory, such as video and audio, the information capacity that can be recorded on the recording medium is limited, and at the same time, the recorded information can be read from the recording medium, Since there is a restriction on the transfer rate of information (information amount per hour that can be transmitted) when transmitting via a communication line, there is a trade-off relationship between the amount of information that can be used for video and the amount of information that can be used for audio. As a result, there is a problem that the image quality and sound quality of the content are in a state of trade-off. In other words, when a large amount of information is allocated to video with priority on image quality, processing such as limiting the frequency band of sound or applying compression is required to reduce the amount of data allocated to audio data, resulting in a decrease in sound quality. Decrease the sensuous artistic value, such as impairing the expression effect. On the other hand, if you give priority to sound quality and allocate a large amount of sound information, processing such as reducing or compressing the image to reduce the amount of data allocated to the image data will require processing, reducing the image quality, and rendering effects. Detract from the sensual artistic value.

  Sixth, if the sound for information transmission such as loud sound broadcasting coexists with other sounds that have a characteristic of obstructing transmission such as remarkable background noise, “If you do not turn up the volume, you can not hear the necessary information” There is a problem that a contradictory phenomenon occurs that “the volume becomes loud and uncomfortable”. Similar problems exist in various situations. For example, sound effects of audio / video content and theatrical sound effects cannot be achieved unless the volume is turned up. There is a contradictory problem that raising the value makes it uncomfortable.

  In order to solve the above problems, the present inventors can guide the hypersonic effect by clarifying the detailed structural features of vibration that can lead to the fundamental brain activation effect. As an apparatus and method for generating vibration, a vibration signal having an autocorrelation order is defined and disclosed in cited document 8 and the like.

  Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In addition, in each following embodiment, the same code | symbol is attached | subjected about the same component.

First embodiment.
In the first embodiment of the present invention, a vibration generating apparatus and method will be described below.

  The vibration generating apparatus and method according to the first embodiment includes an audible range component that is a vibration component in a range from 20 Hz, which is an audible frequency range that humans can perceive as sound, to one frequency of 15 kHz to 20 kHz. And a predetermined maximum frequency (for example, 88.2 kHz, 96 kHz, 100 kHz, 176.4 kHz, 192 kHz, 200 kHz, 300 kHz, 352.8 kHz, 384 kHz, 500 kHz, 705.6 kHz, 768 kHz, Vibration having an ultra-high frequency component within a range up to 1 MHz, 1.4 MHz, or 2.8 MHz (in the case of a PCM signal, all are maximum frequencies and the sampling frequency is twice these frequencies). And the vibrations are detailed. Because it has an “autocorrelation order” expressed by at least one of the first property and the second property described immediately below, the fundamental function of the human brain presented with this is shown. The basic brain including the brain stem, thalamus, hypothalamus, and the neural network (basic brain network) that projects extensively into the brain can be guided (basic brain activation effect). It is characterized by generating natural vibrations, artificial vibrations, and synthesized vibrations.

The first property is that the shape of the three-dimensional power spectrum array having a component exceeding 20 kHz of the vibration signal has the following fractal characteristics that are complex with self-similarity. In other words, the “fractal dimension local index” expressing the self-similarity of the above shape is the “phase dimension” of the plane when the “time frequency structure index” as a scale for measuring it is in the range of 2 ⁻¹ to 2 ^−5. A value that is different from the dimension number 2 and that is different from the dimension number 3 that is the “phase dimension” of the cube, always takes a value of 2.2 or more and 2.8 or less, and the time-frequency structure index is 2 ⁻¹ to 2 Even if it changes in the range of ⁻⁵ , the fractal dimension local index does not change greatly, and the fluctuation range falls within 0.4.

  Here, the three-dimensional power spectrum array of vibration signals refers to a signal of 51.2 seconds of vibration that is a vibration candidate that can lead to the fundamental brain activation effect, a sampling frequency of 192 kHz, and a quantization bit number of 24 bits. Or, digitize with 12 bits, standardize the variance of the whole signal, divide the whole into unit analysis interval length 200ms, unit analysis interval overlap 50%, and use the Yule-Walker method for each interval Power spectrum estimation is performed with a model order of 10, and band components from 20 kHz to 96 kHz exceeding the upper limit of the human audible range are extracted from the obtained power spectrum. The time change is plotted on the horizontal axis (left to right) on the linear frequency. Display, front and back axes (front to back) are linear display of time, vertical axis (bottom to top) is logarithmic display of power at each time point for each frequency component, cubic Manner and those obtained by rendering.

  The “fractal dimension local index” is the logarithm of the length of one side of the reference box (ie, the cube or cuboid that becomes the “measure”) used when calculating the fractal dimension of the curved surface using the box counting method. When the logarithm of the minimum number of reference boxes necessary to cover the 3D power spectrum array curved surface with the reference box of the axis and its size is the vertical axis, and the required number of reference boxes is plotted against the reference boxes of different sizes , A value obtained by reversing the slope of a straight line connecting two adjacent points (that is, the local slope of the graph).

  Furthermore, the “temporal frequency structure index” refers to the length of one side of the reference box used when calculating the fractal dimension local index of the 3D power spectrum array curved surface using the box counting method. Is normalized and expressed as a ratio to the entire frequency bandwidth (horizontal axis) and the entire time (front-rear axis).

  The second property is that the time series of the vibration signal is not completely predictable and regular, is not completely unpredictable and random, and is predictable or irregular. The degree changes with time. That is, the “information entropy density” representing the irregularity of the time series data does not take a value smaller than −5, which is a completely deterministic regular signal such as a sine wave, and white noise. Thus, a completely random signal does not take 0, but always takes a value in the range of -5 or more and less than 0, and in addition, the value takes a constant value in time like a sine wave or white noise. The “entropy variation index” (hereinafter abbreviated as EV-index) representing the degree of temporal change in information entropy density takes a value of 0.001 or more in 51.2 seconds.

  Here, the “information entropy density” of the time-series data of the vibration signal is a 51.2-second signal of vibration that is a vibration candidate that can lead to the fundamental brain activation effect, a sampling frequency of 192 kHz, and a quantization bit number Digitized in 24-bit or 12-bit, the whole is divided into unit analysis section length of 200 milliseconds and unit analysis section overlap 50%, and power spectrum estimation with autocorrelation model order 10 using Yule-Walker method for each section And calculate from the obtained power spectrum. The “entropy variation index EV-index” is the variance of all analysis target sections of the information entropy density of each unit analysis section.

  In the first embodiment, vibrations generated by one or more vibration generators existing in the space are also emitted into the space, or the vibrations are added in the space or interfere with each other. Or the entire space resonates with those vibrations to generate vibrations having the above autocorrelation order characteristics. In the first embodiment, there is provided a vibrating body that is a gas, liquid, solid, or a composite thereof in a vibrating state having the characteristics of the autocorrelation order. Furthermore, the vibration signal that can induce the generated fundamental brain activation effect is preferably recorded on a recording medium such as an optical disk, a memory, or a hard disk that can be read by a computer, a network server, or the like, or preferably wired. Alternatively, the data is transmitted by a communication device such as wireless or infrared communication, a communication system, or a broadcasting system.

  Next, an example of fundamental brain activation by vibration generated to have a predetermined property will be described below. First, the super-high frequency component which is an essential condition will be described below.

  FIG. 1 is a spectrum diagram showing a frequency spectrum of vibration having an audible range component which is a vibration component in the audible frequency range and having an ultrahigh frequency component exceeding the audible frequency range. That is, in FIG. 1, it is a vibration having a component in the range from 20 Hz to 15 kHz to 20 kHz, which is an audible frequency range that humans can perceive as sound, and exceeds the above audible frequency range and has a predetermined maximum frequency (in FIG. Indicates a power spectrum obtained by using the FFT method for an example of a vibration having a super-high frequency component in a range up to a maximum frequency of 100 kHz.

  Next, “autocorrelation order” will be described. The additive set of elements, including atoms and molecules that make up the inorganic material world, is characterized by the fact that thermal entropy or "randomness" increases unidirectionally over time according to the second law of thermodynamics. On the other hand, in complex structures that exist in nature, including life, elements including atoms and molecules with these characteristics are different from deterministic regularity represented by Euclidean geometry and Cartesian mathematics. It is created by self-organizing according to some “order”. These characteristics include, for example, the biological phenomena of cells and living bodies that are based on mechanisms such as the hierarchy of biomolecules, the control of life activity by genes, and the use of energy using adenosine triphosphate, and the structures they produce. Typically seen in For natural structures other than life phenomena, for example, trends similar to rock composition, topography and crystal structure can be found. In addition, artificial objects that are highly compatible with the senses and sensibilities of “human beings” created as one of the natural structures self-organized in this way, such as highly natural Japanese gardens and folk instrument sounds, etc. A similar structure can be seen.

  The concept representing “ordered but not messy but structured” that is widely seen in highly natural structures related to life phenomena is called “autocorrelation order”. This is a concept that comprehensively expresses the universal phenomenon that a structure is created by organizing according to the correlation that it has internally or by organizing. Structures created by autocorrelation order include, for example, self-similarity expressed in the fractal dimension, time-series structures that show a moderate range of information entropy density that is neither completely random nor completely regular, and temporal May show characteristics such as structural change and chaos. Autocorrelation order can be said to be a concept encompassing the characteristics of these complex systems.

  Next, the first property relating to autocorrelation order will be described. Intricate and intricate structures of natural structures in nature often show exactly the same shape as before expansion (eg, tree branching, tree leaf veins, coastline, human body Blood vessel distribution, alveolar distribution within the lung, etc.). In this way, when a similar structure is recursively repeated from a coarse level to a fine level within a certain range, the fractal dimension that expresses the complexity of the shape and self-similarity within that range. It takes a constant value different from the phase dimension.

  The present inventors have found that the vibration that can lead to the fundamental brain activation effect is obtained when the time-frequency structure of the vibration signal in the ultrahigh frequency region exceeding the upper limit of the human audible range of 20 kHz is displayed as a curved surface of the three-dimensional power spectrum array. Because the structure has a recursive complexity like a natural structure, when a fractal dimension is obtained using a “measurement” with a size within a certain range, It was found that the local index of the fractal dimension falls within a certain range even if the size of the ruler changes.

  On the other hand, the fractal dimension of the three-dimensional power spectrum array of vibrations that do not have a fundamental brain activation effect, such as white noise or sine wave vibration signals, is 2 or close to the phase dimension of the plane. The local index varies greatly depending on the size of the “measurement”.

  Here, the “fractal dimension local index” is a logarithm of the length of one side of a reference box (ie, a cube or cuboid that becomes a “measure”) used when calculating the fractal dimension of a curved surface using the box counting method. The horizontal axis is the logarithm of the minimum number of reference boxes required to cover the 3D power spectrum array curved surface with the reference box of that size, and the required number of reference boxes is plotted against the reference box of different sizes. In this case, the slope of a straight line connecting two adjacent points is an opposite sign.

  In general, when the fractal dimension is obtained using the box counting method, a value obtained by reversing the slope of the regression line obtained from the above graph is the fractal dimension. Therefore, the fractal dimension local index is a local gradient (that is, a differential value) of the graph. In the discretized data, the differential value is obtained from the difference.

  FIG. 2 is a diagram showing a three-dimensional power spectrum array of gamelan instrument sounds, and FIG. 3 is a diagram showing a three-dimensional power spectrum array of rainforest environmental sounds. Here, in FIG. 2 and FIG. 3, the three-dimensional range from 20 kHz to 96 kHz, which is the upper limit of the human audible range, was created to examine the first property relating to autocorrelation order among vibrations having super-high frequency components. An example of a power spectrum array is shown. This is because the signal of vibration of 51.2 seconds is digitized with a sampling frequency of 192 kHz and the number of quantization bits of 24 bits or 12 bits, the variance of the entire signal is standardized, and the whole unit analysis interval is 200 milliseconds. The analysis section is divided into 50% overlaps, and the power spectrum is estimated with the order of autocorrelation model 10 using the Yule-Walker method for each section. From the obtained power spectrum, the upper limit of the human audible range is exceeded. Extraction of band components, the time change, the horizontal axis (left to right) linear frequency display, the front and rear axis (front to back) linear time display, the vertical axis (bottom to top) of each frequency component The logarithmic display of power at each time point was obtained by drawing three-dimensionally.

FIG. 4 is a graph showing an example of a fractal dimension local index of a time-frequency structure of vibration that satisfies the first property regarding the autocorrelation order according to the present invention. Here, the fractal dimension local index of the curved surface of the obtained three-dimensional power spectrum array is calculated using a box counting method. The calculation method will be described in detail in “Supplementary explanation of calculation formula” described later. In FIG. 4, these vibrations are “time-frequency structure indices” in which a fractal dimension local index representing the complexity and self-similarity of the shape of a three-dimensional power spectrum array having a component exceeding 20 kHz is a reference scale for measuring it. Even if the ST-index changes in the range of 2 ^{−1 to} 2 ⁻⁵ , the ST-index always takes a value of 2.2 to 2.8, which is larger than the number of phase dimensions 2 of the planar figure, and The fluctuation range is within 0.4. FIG. 5 shows the fractal dimension local index of the vibration satisfying the first property relating to the autocorrelation order in the range of “time frequency structure index” ST-index of 2 ⁻¹ to 2 ⁻⁵ . The maximum value of the data exemplified here is 2.709, but this value varies depending on how the sample to be analyzed is taken, and can take values up to 2.8.

  Here, the “temporal frequency structure index” ST-index is the analysis target of the length of one side of the reference box used when calculating the fractal dimension local index of the three-dimensional power spectrum array surface using the box counting method. It is normalized and expressed as a ratio to the entire frequency bandwidth (horizontal axis) and the entire time (front-rear axis) of the three-dimensional power spectrum array.

FIG. 6 is a graph showing an example of the local exponent of the fractal dimension of the time-frequency structure of vibration that does not satisfy the first property relating to the autocorrelation order according to the present invention. As is apparent from FIG. 6, an example of a vibration that does not satisfy the first property regarding the autocorrelation order among vibrations having a super-high frequency component is shown. In these examples, the time frequency structure index is in the range of 2 ⁻¹ to 2 ⁻⁵ , and the fractal dimension local index is less than 2.2. That is, white noise time when the frequency structure index of 2 ^-1, pink noise and when the time-frequency structure index is 1 bit noise of 2 ^-1 and ^2-2, the time-frequency structure index in sine wave 2 ^-1, When 2 ⁻³ , 2 ⁻⁴ , and 2 ⁻⁵ , the fractal dimension local exponent takes a value less than 2.2. Further, in white noise, the fluctuation range of the fractal dimension local exponent shows a value larger than 0.4. In addition, FIG. 7 shows a fractal dimension local index in the range where the time-frequency structure index ST-index is 2 ⁻¹ to 2 ⁻⁵ of vibration that does not satisfy the first property related to the autocorrelation order.

  Next, the second property regarding the autocorrelation order will be described. Many of the time series with autocorrelation order observed in nature exhibit structures that are not completely random and not completely regular. In other words, it is not a time series that is completely random and has no predictability like white noise, but is also a time series that is completely predictable and has definite regularity such as sine waves. Rather, it has both inherent predictability and irregularity in the autocorrelation order.

  The inventors of the present invention have found that the vibration that can lead to the fundamental brain activation effect has a signal with moderate predictability and irregularity, and the autocorrelation structure changes with time. On the other hand, vibrations whose time series are completely irregular and have no predictability, such as white noise, do not lead to the fundamental brain activation effect. Similarly, a vibration whose time series is completely regular and whose predictability is definite, such as a sine wave, does not lead to the fundamental brain activation effect.

  Therefore, when the “information entropy density”, which is an index of signal irregularity, is found, vibrations that can lead to the fundamental brain activation effect are completely irregular and unpredictable vibrations such as white noise, for example. Shows a value within a certain range between perfectly regular and definite vibrations such as sine waves, while vibrations that do not lead to fundamental brain activation effects, such as white noise In a vibration consisting of a completely irregular signal, the information entropy density always takes the maximum value theoretically, and a vibration consisting of a completely deterministic signal among those that do not lead to the fundamental brain activation effect, For example, a sine wave theoretically always has a minimum value. Furthermore, in the vibration that can lead to the fundamental brain activation effect, the autocorrelation structure changes with time, so the information entropy density varies over a certain range in time, whereas the fundamental brain activation effect For unguided vibrations such as white noise and sine waves, it always shows a constant value.

  FIG. 8 is a graph showing an example of the information entropy density of vibration satisfying the second property relating to the autocorrelation order according to the present invention and its temporal change. Here, the information entropy density of vibration is obtained by digitizing a signal for 51.2 seconds of vibration to be analyzed with a sampling frequency of 192 kHz and a quantization bit number of 24 bits or 12 bits, and a unit analysis interval of 200 milliseconds. Dividing into 50% overlapping sections, and using the Yule-Walker method for each section, the power spectrum is estimated with the autocorrelation model order 10 of the time series signal, and based on a predetermined calculation formula from the obtained power spectrum (See “Supplementary explanation of calculation formula” described later). The signal that can lead to the fundamental brain activation effect has an information entropy density that is always in the range of −5 or more and less than 0. As described later in detail with reference to FIG. large.

  FIG. 9 is a graph showing an example of the information entropy density of vibration that does not satisfy the second property relating to the autocorrelation order according to the present invention and its temporal change. As is clear from FIG. 9, among the vibrations that do not lead to the fundamental brain activation effect, the white noise always has an information entropy density of 0, the sine wave always takes a value of -5 or less, and is flat with no time change. It is. Pink noise and 1-bit quantization noise have values of −5 or more and less than 0, but hardly change with time.

  For the vibration shown in FIG. 8 and FIG. 9, “Entropy Variation Index” indicating the degree of time change of the information entropy density is shown in the graph of FIG. That is, FIG. 10 is a graph showing an example of an entropy fluctuation index EV-index of vibrations that satisfy and do not satisfy the second property relating to the autocorrelation order according to the present invention. The entropy variation index EV-index is the variance of all analysis target sections of the information entropy density of each unit analysis section. In the vibration satisfying the second property shown in FIG. 8, the entropy fluctuation index EV-index takes a value of 0.001 or more, whereas in the vibration not satisfying the second property shown in FIG. 9, the entropy. The variation index EV-index takes a value less than 0.001. Incidentally, the theoretical upper limit value of the entropy fluctuation index EV-index is a signal in which the information entropy density alternately takes values of −5 and 0, and is 6.2622 under the above-described conditions.

  As described above, the vibration has an audible range component that is a vibration component in an audible frequency range that humans can perceive as a sound, and an ultra high frequency component within a range up to a predetermined maximum frequency beyond the audible frequency range. A vibration having the characteristic represented by at least one of the first property and the second property of the autocorrelation order, Activating the basic brain, including the brainstem, thalamus, hypothalamus, and the neural network (fundamental brain network) that projects into the brain based on the brainstem, thalamus, hypothalamus, etc. The vibration that can lead to the brain activation effect is synonymous with hypersonic sound.

  Next, the human brain is activated by presenting the gamelan musical instrument sound, which is a percussion instrument made of bronze in Bali, Indonesia, which is a typical air vibration that satisfies the first and second properties related to the essential conditions and autocorrelation order. Examples that lead to the effects are shown below.

  FIG. 11 shows an average power spectrum of air vibration of gamelan musical instrument sound obtained by the FFT method. It has a very high frequency component with an upper limit of up to 100 kHz and satisfies the essential conditions of the present invention for the frequency component.

  FIG. 12 shows the fractal dimension local index obtained by a predetermined method for the first property regarding the autocorrelation order of the gamelan instrument sound. Since the fractal dimension local index always takes a value of 2.2 or more and the fluctuation range is 0.4 or less, the first property is satisfied.

  FIG. 13 shows information entropy density obtained by a predetermined method for the second property relating to the autocorrelation order of gamelan instrument sounds. As is apparent from FIG. 13, the information entropy density always takes a value of −5 or more and less than 0. FIG. 14 shows the entropy variation index EV-index obtained by a predetermined method. As is clear from FIG. 14, the entropy variation index EV-index has a value larger than 0.001. From these, the gamelan instrument sound satisfies the condition of the second property regarding the autocorrelation order.

  FIG. 15 is a block diagram of a vibration generator including the configurations of a positron emission tomography apparatus (PET) and an electroencephalogram measurement apparatus used in this embodiment, and a perspective view showing a room 20 for generating vibration by the vibration generator. FIG.

As shown in FIG. 15, the instrument sound obtained by playing the gamelan 1 is collected by the microphone 2. The microphone 2 converts the input instrument sound into an analog electric signal, and outputs the converted analog electric signal to the AD converter 4 via the preamplifier 3. The AD converter 4 AD-converts the input analog electric signal into a digital signal at a sampling frequency of 1.92 MHz by, for example, a high-speed sampling 1-bit quantization method devised by Dr. Yoshio Yamazaki. Output.

  The magnetic recording / reproducing apparatus 10 includes a magnetic recording unit 11, a magnetic recording head 12, a magnetic reproducing head 14, and a magnetic reproducing unit 15, and records a digital signal on the magnetic tape 13 or on the magnetic tape 13. This is a so-called digital signal recorder that reproduces and outputs a recorded digital signal. Here, the magnetic recording / reproducing apparatus 10 records a digital signal AD-converted by a high-speed sampling 1-bit quantization method devised by Dr. Yoshio Yamazaki on a conventional DAT, and is uniform in a frequency range up to 150 kHz. Has frequency characteristics. The magnetic recording unit 11 modulates a carrier wave signal by a predetermined digital modulation method according to the digital signal input from the AD converter 4, and uses the magnetic recording head 12 to modulate the modulated signal in a predetermined direction 16 indicated by an arrow. On the other hand, the magnetic reproducing unit 15 reproduces the modulation signal recorded on the magnetic tape 13 by using the magnetic reproducing head 14, and the reproduced modulation signal is converted into the digital modulation method. The digital signal is extracted by demodulating with the reverse digital demodulation method.

  The demodulated digital signal is DA-converted to the original analog signal by the DA converter 5 and then output through the regenerative amplifier 6. The output analog signal from the regenerative amplifier 6 is cut off by the switches SW1 and 22kHz. The signal is input to the right speaker 9aa and the left speaker 9ab that can generate a signal in the frequency range from 20 kHz to 150 kHz via a high-pass filter (high-pass filter) 7a and a power amplifier 8a, and the switches SW2 and 22kHz are cut. The signal is input to the right speaker 9ba and the left speaker 9bb that can generate a signal of 20 kHz or less via a low-pass filter (low-pass filter) 7b having an off frequency and a power amplifier 8b. Therefore, the crossover frequency of the two filters 7a and 7b is 22 kHz.

  The speakers 9aa, 9ab, 9ba, 9bb are placed in a room 20 that is an acoustically sealed sound insulation room, and the speakers 9aa, 9ab, 9ba, 9bb convert the input signals into vibrations, respectively. Presented to the listener 30 to be measured.

  On the scalp of the listener 30, for example, on 12 scalp points (Fp1, Fp2, F7, Fz, F8, C3, C4, T5, Pz, T6, O1, O2) according to the International 10-20 method Each of the detection electrodes is installed, and the electroencephalogram detection and transmission device 32 connected to each detection electrode converts the electroencephalogram detected by each detection electrode into a radio signal and transmits the radio signal from the antenna 33 to the antenna 34. The electroencephalogram radio signal is received by the antenna 34 and then output to the electroencephalogram data reception / recording apparatus 31. In the electroencephalogram data receiving / recording apparatus 31, the received electroencephalogram radio signal is converted into an electroencephalogram signal and then recorded in a magnetic recording apparatus. Further, the electroencephalogram signal is analyzed by an analysis computer, while a CRT display or pen Record and output changes in brain waves using an output device such as a recorder. On the other hand, the head of the listener 30 is placed between two detectors of the tomography apparatus detection device 42, and the detection signal from the tomography apparatus detection device 42 is transmitted to the tomography apparatus 41. After that, the tomography apparatus 41 executes a predetermined tomography analysis process based on the input detection signal, and displays the tomography map of the analysis result on the built-in CRT display.

  In the vibration generating apparatus and the room 20 configured as described above, when both the switches SW1 and SW2 are turned on, the musical instrument sound played using the gamelan 1 is recorded on the magnetic tape 13 in the magnetic recording / reproducing apparatus 10. Then, when it is played back, the playback vibration, which is substantially the same as the musical instrument sound of Gamelan 1, that is, both the audible range component (LFC) and the super-high frequency component (HFC) having a predetermined autocorrelation order are 9aa, 9ab, 9ba, 9bb can be used to present to the listener's human 30. This condition is called a full range state condition (hereinafter referred to as FRS condition). Here, by turning on and off the switches SW1 and SW2, vibrations of gamelan instrument sounds having various frequency components can be generated by the speakers 9aa, 9ab, 9ba, and 9bb. That is, when only the switch SW1 is turned on, the vibration of only the super-high frequency component (HFC) of 22 kHz or more is presented to the human person 30 of the listener. This condition is called the HFC single condition. On the other hand, when only the switch SW2 is turned on, the vibration of only the audible range component (LFC) of 22 kHz or less is presented to the listener 30. This condition is called LFC single condition. When both the switches SW1 and SW2 are turned off, the baseline background noise component (hereinafter referred to as the air vibration generated by the equipment in the room 20 and the negligibly small thermal noise component of the power amplifiers 8a and 8b). , Referred to as a background noise component) is presented to the listener 30. This condition is called a background noise condition.

  The activity of the fundamental brain was measured by recording the regional cerebral blood flow and electroencephalogram of the listener who presented the vibration of gamelan instrument sound simultaneously or independently.

  FIG. 16 shows the experimental results measured by the apparatus shown in FIG. 15. The cerebral blood flow under the FRS condition in which the audible range component and the ultrahigh frequency component are simultaneously presented with respect to the LFC single condition in which only the audible range component is presented. FIG. 16 (a) is a projected view along the sagittal suture of the listener's skull (sagittal projection), and FIG. 16 (b) is its coronal shape. FIG. 16C is a projection view along the stitching (coronal projection view), and FIG. 16C is a horizontal plane projection view thereof. That is, FIG. 16 is a graph in which the Tairach coordinates (x, y, z) = (4 mm, −26 mm, −8 mm), that is, the brain stem where the cerebral blood flow significantly increases in the FRS condition with respect to the LFC single condition in this embodiment. FIG. 6 is a projection view showing a portion 101 corresponding to, and a Tairaich coordinate (x, y, z) = (− 16 mm, −18 mm, 0 mm), that is, a portion 102 corresponding to the left thalamus. As apparent from FIG. 16, the FRS condition in which the audible range component and the super-high frequency component were simultaneously presented is the brainstem and left side compared to the LFC single condition in which only the audible range component was presented to the listener 30. It can be seen that cerebral blood flow is significantly increased in the thalamus.

  FIG. 90 is a graph showing the normalized cerebral blood flow with respect to each frequency component, which is an experimental result measured by the apparatus of FIG. 15, and FIG. 90 (a) is a graph showing the cerebral blood flow at the position of the brain stem. FIG. 90 (b) is a graph showing the cerebral blood flow at the position of the left thalamus. As is clear from FIG. 90, in the brainstem and the left thalamus, the LFC alone condition presenting only the audible area component significantly decreased the cerebral blood flow volume not only in the FRS condition but also in the background noise condition. I understand that.

  FIG. 17 is a graph showing experimental results measured by the apparatus of FIG. 15 and normalizing the potential (square root of power) of the α band component (8-13 Hz) of the spontaneous brain wave with respect to each frequency component. is there. As is clear from FIG. 17, the listener 30 is compared with the LFC single condition that presents only the audible range component, the HFC single condition that presents only the super-high frequency component, or the background noise condition that presents only the background noise component. Thus, it can be seen that the α band component potential of the spontaneous electroencephalogram is increased under the FRS condition in which the audible range component and the superhigh frequency component are presented simultaneously.

  The brainstem and thalamus, whose regional cerebral blood flow is increased in FIG. 16, are portions corresponding to “mountains”, that is, the statistical significance is maximized. Therefore, in order to depict the whole image of the neural network to which these brain parts belong, the representative spatial pattern included in the fluctuation of the whole data is extracted as the principal component using principal component analysis, The main components including the brain stem and the thalamus were searched.

  FIG. 18 is an experimental result measured by the apparatus of FIG. 15 and shows a sagittal section (sagittal section) of an image rendered as a principal component including the brain stem and thalamus by principal component analysis of regional cerebral blood flow data. It is. As a result of the principal component analysis, the “basic brain” including the brain stem and the thalamus shown in FIG. 16 and the “basic brain” including the hypothalamus as a base and further including the entire neural network projected from the basic brain to the prefrontal cortex and the zonal gyrus The “brain network” was depicted as the second principal component showing the second largest variation in the whole. Note that the first principal component is considered to be a response of the auditory cortex to audible range sounds.

  The core brain, as its internal structure, comprehensively manages the generation of pleasant, beauty, and emotional responses in humans, and is a rewarding nerve system such as the monoamine nervous system and opioid nervous system that are closely related to behavioral control. Includes circuitry. When the activity of the basic brain and the neural network (basic brain network system) that is widely projected to the whole brain is improved, the aesthetic sensitivity to various sensory inputs in general including sound is enhanced, and the pleasure, beauty, and impression are enhanced. In addition to enhancing the response, it has the effect of strengthening the behavior (sensory receptive behavior or approaching behavior) that positively accepts such sensory input.

  Conversely, abnormalities in the basic brain and basic brain network (basic brain network system) are directly related to monoamine nervous system abnormalities such as depression, schizophrenia, dementia, chronic fatigue syndrome, and attention deficit hyperactivity syndrome. It is known that it causes various mental illnesses and causes psychiatric and behavioral abnormalities that are a major problem in modern society, such as suicide, self-harm, and abnormal aggression.

  In addition, the basic brain is the highest center of the autonomic nervous system and endocrine system, and by controlling the immune system through these, it plays a role in maintaining the homeostasis of the whole body (homeostasis) and the function of biological defense Abnormal activity of the fundamental brain leads to the breakdown of the above-mentioned homeostatic function, leading to metabolic syndrome such as hypertension, hyperlipidemia, diabetes, cancer, cerebrovascular disorder, heart disease, hay fever and atopic skin It is closely related to the onset of lifestyle-related diseases that are rapidly increasing in modern society, such as immune diseases including allergies such as flames.

  Furthermore, in FIG. 19, the band component of the spontaneous brain wave which fluctuates in parallel with the change in the activity intensity of the basic brain and the entire basic brain network depicted in FIG. Spontaneous electroencephalograms measured from 12 electrodes (Fp1, Fp2, F7, Fz, F8, C3, C4, T5, Pz, T6, O1, O2) arranged on the scalp according to the international 10-20 method, 2-4 Hz), θ band (4-8 Hz), α1 band (8-10 Hz), α2 band (10-13 Hz), β band (13-30 Hz), and the potential (power) of each band component for each electrode. Of which band component recorded from which electrode correlates with the change in activity intensity of the above-mentioned basic brain and basic brain network derived from the simultaneously measured regional cerebral blood flow. . As a result, the potential of the α2 band component of the electroencephalogram recorded from the seven electrodes (C3, C4, T5, Pz, T6, O1, O2 by the international 10-20 method) placed at the center, top, and back of the scalp. However, there was a statistically significant positive correlation with the change in the activity intensity of the basic brain network shown in FIG.

  FIG. 19 shows experimental results measured by the apparatus shown in FIG. 15 and shows the distribution on the scalp of the correlation coefficient between the potential of the electroencephalogram α2 band component and the change in the activity intensity of the basic brain and the basic brain network. Based on these results, the central, parietal, and occipital 7 electrodes (C3, C4, T5, Pz, T6 according to the international 10-20 method) that are statistically significantly positively correlated with changes in the activity intensity of the basic brain network. , O1, O2), a value obtained by normalizing and averaging the potential value of the electroencephalogram α2 band component recorded as a deep brain activity index (DBA-index). The deep brain activity index DBA-index is an index that reflects the activity of the fundamental brain and the fundamental brain network based on brain wave data that can be easily recorded without performing regional cerebral blood flow measurement that requires a large-scale device. Can be used as

  Next, a gamelan musical instrument that is a typical air vibration having a super-high frequency component which is an essential condition as a vibration capable of leading to the fundamental brain activation effect and satisfying the first property and the second property regarding the autocorrelation order The following is an example in which ultra high frequency vibration exceeding the upper limit of the human audible range is received by the “body surface” and the fundamental brain activation effect is induced by using sound and the brain wave measurement of the human being presented with the sound.

  In humans, due to the ossicles in the middle ear and the mechanical properties of the basement membrane in the cochlea in the inner ear, air vibrations at frequencies above 20 kHz are hardly transmitted to hair cells that convert mechanical vibrations into neural activity. This is because, when humans receive an ultra-high frequency component with the autocorrelation order characteristic that is essential for activating the fundamental brain activation effect, some receptive response system other than the human air conduction auditory system is involved. Suggests that

  Therefore, in the experiment according to this example, in order to examine whether the fundamental brain activation effect is a normal response of the air conduction auditory system alone or other receptor response systems are involved, The frequency component of the gamelan instrument sound, which is a typical air vibration that has the first property and the second property related to the autocorrelation order, having the super-high frequency component that is an essential condition as the vibration that can lead the effect, The filter is divided into an audible region component of 22 kHz or less and an ultra-high frequency component of 22 kHz or more, and the super-high frequency component is selectively applied only to the air conduction auditory system under the condition that the audible region component is presented to the air conduction auditory system. Present, or vice versa, the high-frequency component is presented on the body surface that will contain various other vibration-receptive systems excluding the air conduction auditory system, and the fundamental brain activation effect occurs between the two The difference between Or, if there is a difference, it was decided to compare what about differences in either.

  Here, FIG. 20 is a block diagram showing a configuration of a vibration generating apparatus which is an earphone experimental apparatus used in the present embodiment. In the experimental apparatus of FIG. 20, using a high-pass filter (high-pass filter) and a low-pass filter (low-pass filter) 311 and 312 having an attenuation factor of 80 db / oct and a pass frequency band ripple of ± 1 dB, Each stereo sound source signal having a crossover frequency of 22 kHz is separated and filtered into an audible range component and a super-high frequency component, and both are amplified independently, and then passed through the earphones 334 and 334 and / or the speaker systems 330 and 330. Each was presented separately or simultaneously.

  In FIG. 20, a predetermined signal source disk 300 is set on the player 301 to reproduce signal data of gamelan instrument sound vibration. The signal data is DA-converted and amplified by the preamplifier 302, and then the high-pass filters (high-pass filters HPF) 311 and the low-pass filters (low-pass filters LPF) of the left channel circuit 310 and the right channel circuit 320. 312 is input. The left channel circuit 310 and the right channel circuit 320 are a high-pass filter (high-pass filter HPF) 311, each low-pass filter (low-pass filter LPF) 312, four switches SW 1, SW 2, SW 3, SW 4, and an ultra-high frequency Power comprising an earphone amplifier 313 comprising an HFC channel earphone amplifier 313a for components and an LFC channel earphone amplifier 313b for audible range components, an HFC channel power amplifier 314a for ultra-high frequency components, and an LFC channel power amplifier 314b for audible range components The amplifier 314 is configured in the same manner. In both channel circuits 313 and 314, the electrical signal of the super-high frequency component (HFC) output from the high-pass filter (high-pass filter) 311 is passed through the switch SW1 and the HFC channel earphone amplifier 313a, and the tweeter phone element of the earphone 334 is used. And output to the tweeter 331 of the speaker system 330 via the switch SW3 and the HFC channel power amplifier 314a. The audible range component (LFC) electrical signal output from the low-pass filter (low-pass filter) 312 is output to the audible range full-range earphone element 334b of the earphone 334 via the switch SW2 and the LFC channel earphone amplifier 313b. At the same time, it is output to the audible range reproduction full range speaker 332 and the woofer 333 via the switch SW4, the LFC channel power amplifier 314b, and the power distribution network 335 of the speaker system 330.

  Here, the pair of speaker systems 330 and 330 are placed on both the left and right sides of the listener 340, and the pair of earphones 334 and 334 are inserted into the ear canal of both ears of the listener 340. Depending on the following experimental conditions, the head 341 of the listener 340 is substantially entirely covered by the full-face helmet 350, and substantially the entire body other than the head 341 of the listener 340 is sound-insulating sound insulation. The entire body coat 360 is substantially entirely covered. Depending on the following experimental conditions, the switches SW1, SW2, SW3, SW4 are turned on or off. Here, the pair of speaker systems 330 and 330 was installed at a position of a distance of 2.0 m from the listener's 340 ear. In addition, the pair of earphones 334 and 334 used was an insertion type that does not have an ear pad developed independently. The ear canal insertion part of the earphone 334 forms a case structure of about 2 to 3 millimeters thick by injection molding of hard plastic, and both the left and right channels are for high frequency components (HFC) and audible range components (LFC). Each has two vibration generating earphone elements 334a and 334b.

Each EEG experiment consisted of 4 sub-experiments. That is, the experimental conditions of the four sub-experiments are as follows.
(1) Present both the audible range component (LFC) and the super-high frequency component (HFC) via the speaker systems 330 and 330.
(2) Present both the audible range component (LFC) and the super-high frequency component (HFC) via the earphones 334 and 334.
(3) The audible range component (LFC) is presented through the earphones 334 and 334, and the super-high frequency component is presented through the speaker systems 330 and 330.
(4) The audible range component (LFC) is presented through the earphones 334 and 334, and the super-high frequency component is presented through the speaker systems 330 and 330, but the head 341 and the body surface of the listener 340 are super-high-frequency components. Those parts are covered with a full-face helmet 350 and a sound insulation whole body coat 360 which are sound insulation materials so as not to be exposed to (HFC).

  Two conditions were compared in each of all the above sub-experiments. That is, a full range state condition (hereinafter referred to as FRS condition) simultaneously presenting an audible range component (LFC) and a super high frequency component (HFC) and an LFC single condition presenting only an audible range component (LFC). All experiments were conducted in an acoustic sound insulation room.

In each experiment, two trials for each of the FRS condition and the LFC single condition were performed with an interval between trials of several minutes. In each trial, gamelan instrument sounds were presented for 400 seconds. The method for measuring the electroencephalogram and the method for obtaining the deep brain activity index DBA-index are the same as those described in detail with reference to FIGS.

  Since the electroencephalogram data show a clear delay with respect to the sound presentation, the statistical evaluation of the difference between the FRS condition and the LFC single condition corresponds to the whole interval 400 seconds, the latter 200 seconds, and the last 100 seconds. Performed using t-test.

  Next, experimental results will be described below. FIG. 21 is a graph showing the DBA-index of each case, which is an experimental result measured by the system of FIG. 20, and shows an average value and a standard error through all listeners. First, as shown in FIG. 21A, when the audible range component (LFC) and the super-high frequency component (HFC) are presented to the listener 340 via the speaker systems 330 and 330, the DBA-index is FRS condition. The lower value was significantly increased as compared with the value under the LFC alone condition, and it was confirmed that the fundamental brain activation effect was generated. The increase in DBA-index became more prominent as the latter half of the sound presentation period was reached. This is in good agreement with our previous reports that there is a time delay in the onset and withdrawal of the fundamental brain activation effect.

  Next, as shown in FIG. 21B, both the super-high frequency component (HFC) and the audible range component (LFC) were selectively presented only to the air conduction auditory system via the earphones 334 and 334. Occasionally, there was no difference in DBA-index between the FRS condition and the LFC single condition, and no expression of the fundamental brain activation effect was found.

  On the other hand, as shown in FIG. 21 (c), the audible range component (LFC) is selectively presented only to the air conduction hearing system via the earphones 334 and 334, and the super high frequency component (HFC). Is shown to the whole body via the speaker systems 330, 330, DBA-index is significantly increased in the FRS condition compared to the LFC single condition, confirming that the fundamental brain activation effect has occurred It was done. Also in this case, as shown in FIG. 21A, the increase in DBA-index became more remarkable as the second half of the sound presentation period was reached.

  Furthermore, as shown in FIG. 21 (d), in the experiment of the same setting, the soundproof material is placed at a position immediately before the super high frequency component (HFC) sent through the speaker systems 330 and 330 reaches the body of the listener. When it is highly attenuated and prevents its arrival at the body surface, the difference in DBA-index between the FRS condition and the LFC single condition does not show statistical significance, and the expression of the fundamental brain activation effect is remarkable. Was suppressed.

  When the above knowledge is integrated, the fundamental brain activation effect that a vibration having an ultra-high frequency component as an indispensable condition and satisfying the first property or the second property relating to the autocorrelation order leads to humans is the air conduction auditory system. Is not involved in its development alone, suggesting that some receptive response system located on the body surface or having a window is involved.

  Next, an example of a device that generates vibrations that can induce a fundamental brain activation effect using an actual object will be described below. An example of a vibration generating device that includes an audible range component and a super-high frequency component as described above and has the above-described predetermined autocorrelation order and generates a vibration (hypersonic sound) that can lead to a fundamental brain activation effect. Indicates. First, an example of a vibration generating apparatus that generates the predetermined vibration (hypersonic sound) using an actual object (gas, liquid, solid) will be described, and then the predetermined vibration is generated from a vibration signal such as electricity or light. An example of a vibration generator that generates vibration (hypersonic sound) will be described.

  As shown in FIGS. 1, 3, 4, 8, and 9, the natural environmental sound of the tropical rainforest, which is the most promising environment in which human genes have evolved, is the upper limit of the human audible frequency. The high frequency components with a predetermined autocorrelation order are abundantly contained in the environmental sound of cities where modern people live. In addition, it does not lead to the effect of activating the fundamental brain, and may reduce the activity of the fundamental brain compared to that under dark noise (see FIGS. 90 and 17). Abnormal activity of the basic brain and the neural network (basic brain network system) projected from the brain to the entire brain leads to various mental and behavioral abnormalities, as well as failure of the homeostatic function and defense function of the whole body. Therefore, it is closely related to the onset of modern diseases such as lifestyle-related diseases that are rapidly increasing. Therefore, focusing on the specific and rapid increase in mental and behavioral abnormalities and lifestyle-related diseases in modern cities, one of the causes is the evolution of the sound environment of modern cities and the evolution of human genes. There is a great possibility that it is very different from the characteristics of the environmental sound of the rainforest, which is the most promising candidate of the formed environment, and contains almost no super-high frequency components having a predetermined autocorrelation order.

  In order to solve this problem, a vibration generator capable of generating a vibration (hypersonic sound) that can lead to a fundamental brain activation effect because it includes a super-high frequency component having a predetermined autocorrelation order It is extremely effective to install it in various spaces including urban spaces and generate hypersonic sounds to present to humans. Further, when a hypersonic sound is generated using an actual object, vibration generated on the spot may be converted into an electrical signal and recorded using a transducer. As a result, it is possible to record and play back hypersonic sound on package media and distribute it via communication and broadcasting, even if it is not in the same space as a vibration generator using real objects. , The opportunity for more people to accept hypersonic sound increases. The abundant acceptance of hypersonic sound leads to a fundamental brain activation effect and can be expected to solve the mental and physical health problems facing modern people.

First, an example of a vibration generator and a vibration signal generator that generate hypersonic sound using an actual object (gas, liquid, solid) will be described.
FIGS. 22 to 28 show vibrations that include an audible region component and a super-high frequency component, have a predetermined autocorrelation order, and can lead to a fundamental brain activation effect by flowing a liquid while colliding with an obstacle. It is an example of the vibration generator which produces | generates (hypersonic sound). As shown in FIGS. 1, 4, 8, and 10, the water sound has the first property and the second property related to the audible range component, the super-high frequency component, and the autocorrelation order, and the fundamental brain activity. This is a vibration that can lead to a crystallization effect. In the following apparatus example, a liquid flow including a water flow is caused to collide with a set obstacle to generate a vibration including a super-high frequency component having a predetermined autocorrelation order. In this way, by generating vibrations (hypersonic sound) that contain audible and ultra-high frequency components and have the characteristics of a predetermined autocorrelation order, the brain controls the generation of pleasure, beauty and emotion in humans. Leads to the activation of the basic brain and the basic brain network (basic brain network system), including the reward system neural circuit and the autonomic nervous system, the endocrine system, and the immune system responsible for maintaining homeostasis and protecting the body. As a result, the effect of enhancing aesthetic sensitivity and improving and improving the state of the body can be obtained.

  FIG. 22 shows a vibration (hypersonic) that includes a audible region component and a super-high frequency component and has a predetermined autocorrelation order and can lead to a fundamental brain activation effect using a liquid flow such as a water flow. FIG. 4 is a perspective view and a cross-sectional view illustrating an example of a vibration generator and a vibration signal generator that generate sound. In FIG. 22, the structure of the flat plate 170 having one or more obstacles such as protrusions whose positions and protrusion dimensions are variable and which can be set at an angle of more than 0 degrees and less than 90 degrees with respect to the horizontal plane. And a liquid flow generator 171 that causes a liquid such as water to flow down on the surface of the flat plate 170, and a vibration that includes transducers 173, 174, and 175 that convert vibration generated when the liquid flows down into the system into an electrical signal. Generator.

  The liquid flowing out from the liquid flow generating device 171 located above the structure of the flat plate 170 collides with the protrusions 172 set on the flat plate 170 in the process of flowing down the surface of the structure of the flat plate 170. Or over the protrusions 172, flow around the protrusions 172, or flow down as splashes. At that time, the liquid contains an ultra-high frequency component having a predetermined autocorrelation order, and therefore generates a vibration (hypersonic sound) that can lead to a fundamental brain activation effect. By converting the air vibration or liquid vibration generated in this way into an electric signal, a vibration (hypersonic sound) signal that can lead to the fundamental brain activation effect can be obtained. The liquid flow generator 171 generates a vibration (hypersonic sound) that can effectively induce the fundamental brain activation effect by controlling the unit time flow rate of the liquid and its fluctuation. For example, the height of the protrusion 172 can be controlled by the actuator 176. Further, the protrusion 172 that is an obstacle to the liquid flow may have a shape other than the plate shape, including the examples shown in the protrusions 172a to 172i of various shapes as shown in the modification (cross-sectional view) of FIG. Well, you may mix them. In addition, by rotating the protrusion 172 with respect to the plate surface, the direction in which the bumped liquid effectively vibrates can be set. In addition, the axis | shaft which rotates the protrusion 172 may be perpendicular | vertical, horizontal, and diagonal with respect to a plate surface. In addition, as shown in the liquid flow generation mechanism 171a according to the modified example of FIG. 22, the nozzle position where the liquid flows out and its unit time flow rate may be controlled by installing a plurality of nozzles and individually controlling them. it can.

In FIG. 24, the protrusion 172 is a vibration (hypersonic sound) that can lead to the fundamental brain activation effect by changing the protrusion of the protrusions adjacent to the top and bottom or right and left to have a specific positional relationship. ) Can be effectively generated. FIG. 24 is an example in which the position of a group of a plurality of protrusions is collectively controlled while maintaining such an effective combination. Further, the height of the protrusion 172 is configured to be controllable by an actuator 176.

In FIG. 22, the protrusions 172 are regularly and regularly arranged. As a result, the flow paths of the liquid flow become orderly, and the amounts of liquid flowing in the respective flow paths become equal while corresponding to each other. The vibration (hypersonic sound) that can lead to the brain activation effect occurs relatively uniformly from the entire surface of the board. On the other hand, in FIG. 25, by arranging the protrusions 172 irregularly, the flow paths become unevenly distributed, and the flow rate of each flow path also changes. As a result, the spatial distribution of the vibration (hypersonic sound) that can lead to the fundamental brain activation effect and the distribution in the liquid are biased, so it is effective when converting the vibration signal into an electrical signal using this Multi-channel recording becomes possible. Also, at this time, by moving the transducer to the electrical signal from the immediate vicinity of one flow path to the close proximity of another flow path, the dynamic process of the kind that cannot be caused by the flow rate change in the same flow path in the moving process. Variations can be added to the vibration signal.

  FIG. 26 shows an example in which the structure of the protrusion as an obstacle of the liquid flow is a mountain shape (for example, a variable depth circular protrusion 178) or a hollow shape (for example, a variable height circular recess 177) according to this embodiment. It is the perspective view and sectional drawing which show this. That is, FIG. 26 is a modification of the shape of the structure that is an obstacle to the liquid flow in the vibration generator shown in FIG. In FIG. 26, the height of the convex part 178 or the height of the concave part 177 is variable. In addition, in the convex part 178 and the recessed part 177, the structure with a some shape may be mixed.

  FIG. 27 is a perspective view showing an example in which the protrusion structure as an obstacle to the liquid flow according to the present embodiment is irregularly arranged in an irregular shape. In FIG. 22, the protrusions 172 having a simple plate shape are arranged regularly and regularly. On the other hand, in FIG. 27, the protrusions 179 having a complicated shape such as natural stone are irregularly arranged. As a result, vibration (hypersonic sound) that can generate a water flow that imitates the water flow with complex flow paths and obstacles that exist in Yamano etc. in a controlled manner, thereby leading to the fundamental brain activation effect. ) Can be generated.

  FIG. 28 shows a vibration (hypersonic) that includes a audible range component and a super-high frequency component and has a predetermined autocorrelation order and can lead to a fundamental brain activation effect using a liquid flow such as a water flow according to the present embodiment. FIG. 5 is a perspective view and a floor sectional view showing an example (horizontal path) of a vibration generator and a vibration signal generator that generate (sound). That is, FIG. 28 is a modification in which the angle of the plate-like structure with respect to the horizontal plane is set to 0 degrees or close to 0 degrees in the vibration generator shown in FIG. In FIG. 28, the liquid channel 230 has a structure in which the liquid channel 230 is bent a plurality of times, and the floor surface 231 has a complicated uneven structure as shown in the sectional view of FIG.

Or it may be placed on the wall.

It is a block diagram which shows the example of the vibration generator and vibration signal generator which generate | occur | produce a hypersonic sound. 29 includes a water drop generator 241 that continuously drops water droplets into, for example, a spherical device housing 240, a device housing 240 that stores the liquid 242 of the dropped water droplets, and the stored liquid and outer wall. It has transducers (or microphones) 243, 244, 245 for converting vibrations into electrical signals, and an audio mixer 246 that adds the vibration signals and outputs a vibration signal as a result of the addition. Here, the falling object may be a liquid other than water or a solid such as a pebble. The liquid to be stored may be water or a liquid other than water. Further, the water droplet generator 241 can adjust the size and frequency of the water droplets so as to effectively generate vibration (hypersonic sound) that can lead to the fundamental brain activation effect.

Leads to the activation of the basic brain and the basic brain network (basic brain network system), including the reward system neural circuit and the autonomic nervous system, the endocrine system, and the immune system responsible for maintaining homeostasis and protecting the body. As a result, the effect of enhancing aesthetic sensitivity and improving and improving the state of the body can be obtained.

  FIG. 30 shows vibrations that include an audible region component and a super-high frequency component and have a predetermined autocorrelation order and can lead to a fundamental brain activation effect by the airflow passing through the gap according to the present embodiment. It is a perspective view which shows the example of the vibration generator which produces | generates a sound, and a vibration signal generator. That is, FIG. 30 generates vibrations (hypersonic sound) that can lead to the fundamental brain activation effect by complex turbulence generated when airflows of various velocities pass through gaps of various shapes. It is an example of a vibration generator. The apparatus of FIG. 30 includes a compressed air generator 256 that generates an air flow by releasing propeller-shaped rotor blades and compressed air, a rectangular parallelepiped apparatus casing 250 connected thereto, and a partition plate 251 that divides the interior thereof. ˜255.

  FIG. 31 shows a vibration that includes an audible range component and an ultra-high frequency component and has a predetermined autocorrelation order and can lead to a fundamental brain activation effect (hypersonic It is a side view which shows the example of the vibration generator which produces | generates a sound. In FIG. 31, one end of a strip-shaped metal piece 260 made of, for example, iron or copper is fixed, and the other end is flipped using a protrusion 262 such as metal fixed to the outer surface of a cylindrical member 261 that rotates. This generates vibrations that can lead to the fundamental brain activation effect. You may have apparatuses, such as a resonance box and a resonance tube, which have a function which amplifies and generates the air vibration which fulfills the above-mentioned property by resonating with the air vibration generated from this vibration generator.

  Next, an example of a device that generates vibration that can lead to the fundamental brain activation effect from the vibration signal will be described below. Here, among examples of vibration generators that include an audible range component and a super-high frequency component, have a predetermined autocorrelation order, and generate a vibration (hypersonic sound) that can lead to a fundamental brain activation effect, An example of a vibration generator that generates the predetermined vibration from a vibration signal such as electricity or light will be described below.

  First, an example of a device that generates a vibration (hypersonic sound) capable of guiding the fundamental brain activation effect from a single vibration signal through a single vibration generation mechanism will be described below.

  FIG. 32 is a block diagram of an apparatus for amplifying an input signal by a vibration signal amplifier and generating vibration from a vibration generating mechanism according to the present embodiment. In FIG. 32, an input signal of vibration (hypersonic sound) that includes an audible range component and an ultra-high frequency component and has a predetermined autocorrelation order and can lead to a fundamental brain activation effect is supplied to the vibration signal amplifier 70. After being input and amplified, the amplified vibration signal is converted into air vibration from the speaker 71 and radiated. In this way, by generating a vibration that includes an audible range component and a super-high frequency component and has a characteristic of a predetermined autocorrelation order, the brain reward system neural circuit that controls the generation of the response of pleasure, beauty and emotion in humans , Leading to activation of the basic brain including the autonomic nervous system, the endocrine system, and the central part of the immune system, which maintain the homeostasis of the whole body and the defense of the body, and the core brain network (basic brain network system), resulting in enhanced aesthetic sensitivity Thus, the effect of improving and improving the physical condition can be obtained.

  The signal input to the apparatus shown in FIG. 32 is a signal input from a broadcast receiver, a receiver of a signal distributed / distributed from an Internet line or a telephone line, a vibration signal synthesizer such as a synthesizer, or the like. It may be a signal inputted by converting vibrations of solid, liquid, gas, etc. into electrical fluctuations by a transducer. Furthermore, the speaker 71 may be a transducer that emits solid vibration or liquid vibration.

  FIG. 33 is a block diagram of an apparatus for generating vibration from a speaker by amplifying a vibration signal reproduced using a vibration signal recording / reproducing apparatus according to the present embodiment with a vibration signal amplifier. In FIG. 33, an electric signal of vibration (hypersonic sound) that includes an audible range component and a super-high frequency component and has a predetermined autocorrelation order and can lead to a fundamental brain activation effect includes Blu-ray discs and the like. After being recorded in advance in various memories including a recording medium such as an optical disk, the recorded electrical signal is reproduced by the vibration signal recording / reproducing device 72. Next, the regenerated electrical signal of the vibration that can lead to the fundamental brain activation effect is input to the vibration signal amplifier 70 and amplified, and then the amplified vibration signal is converted from the speaker 71 into air vibration and radiated. Is done.

The above is a method of generating an actual vibration by converting a signal input to the speaker. In this case, if the super high frequency component is deficient at the stage of the vibration signal input to the speaker, There is a problem that one cannot accept hypersonic sound.
As a solution to this problem, an independent vibration generating function is given to the speaker system itself, and a function of generating vibration of hypersonic sound or its super-high frequency component is provided only by connecting to some device or independently.

  As for a specific method, FIG. 91 shows an example of a vibration generator 370 of the speaker system. As the vibration source, there are a memory 375 for storing the signal of the hypersonic sound or its super-high frequency component, and an auxiliary device such as an amplifier unit 376 and a power supply unit 377 for driving the speaker or the super-high frequency vibration generating element with the signal. Equipped with the speaker system itself. In addition, a device that generates an ultrahigh-frequency component having a predetermined autocorrelation order inside the speaker system may be incorporated.

  As a vibration generating mechanism, in addition to generating a vibration including a super-high frequency component having a predetermined autocorrelation order using the vibration generating mechanism of the speaker itself, there are the following means. A vibration generation function is built in the speaker system to vibrate the housing itself. Alternatively, the high-frequency vibration generating elements 372 and 373 are equipped (embedded, pasted, wound, etc.) on the housing or the like. Further, the outside of the housing or the like is covered with a material such as piezo plastic. Further, the super high frequency vibration generating elements 372 and 373 are connected to generate vibration. Also, the cable 374 connecting the device and the speaker system can be equipped with a super-high frequency vibration generating element.

  As a power supply method, power may be supplied from an external power supply, or a power supply unit 377 and a battery (a primary battery (dry battery), a secondary battery (storage battery), a built-in fuel cell, etc.) may be incorporated. In addition, as a method of supplying power from a connected device, there is a phantom method, that is, a method of supplying power by superimposing a DC power supply on an audio cable, a method of coexisting audio signal transmission and power supply using a USB cable or the like. In addition, a wireless power feeding mechanism may be provided.

  As a result, listeners can receive hypersonic sound even when connected to a device that does not have a function to generate vibration signals in the ultra-high frequency band. In addition to being able to prevent deterioration and ensure safety, by activating the basic brain and the basic brain network (basic brain network system), an active effect of improving and improving the state of mind and body can be obtained.

FIG. 34 is a perspective view showing the appearance of the portable player 501 according to the second embodiment of the present invention. In the present embodiment, the hypersonic sound signal having the autocorrelation order property defined in the first embodiment and capable of deriving a hypersonic effect is referred to as an HS signal, and a frequency component exceeding the frequency in the audible range. A high-resolution (high-resolution or high-definition) signal including a high-definition signal is referred to as an HD signal.

  FIG. 35 is a block diagram showing the configuration of the portable player of FIG.

  In FIG. 35, an HS signal memory 512 stores in advance data of an HS signal having the property of autocorrelation order defined in the first embodiment, and reproduces a predetermined HS signal based on an instruction signal from the controller 510. To the D / A converter 513. The D / A converter 513 D / A converts the input HS signal and outputs it to the VCA circuit 520.

  The mobile phone wireless communication circuit 514 receives the audible range sound signal, HS signal, or HD signal received from the antenna 514A after being distributed from the predetermined server device via the mobile phone network, demodulates, and receives the predetermined signal. After executing the processing, the processed signal is output as a streaming signal via the signal register 516 to the VCA circuit 520 via the D / A converter 517, and an audible range sound signal via the low-pass filter 531. Only to the mixer circuit 540. In addition, when the received signal is not a streaming signal but a download signal that can be stored in the memory, the mobile phone wireless communication circuit 514 outputs the processed signal to the signal memory 518 and stores it, and if necessary, the controller 510 In response to the instruction signal from the signal, the signal is read out from the signal memory 518 and output as a download signal to the VCA circuit 520 via the D / A converter 519 and to the audible range sound signal via the low-pass filter 531. Only to the mixer circuit 540.

  The WiFi wireless communication circuit 515 receives and demodulates an audible range sound signal, HS signal, or HD signal received using an antenna 515A after being distributed from a predetermined server device via a predetermined network such as the Internet. Then, the processed signal is output as a streaming signal via the signal register 516 to the VCA circuit 520 via the D / A converter 517 and audible via the low-pass filter 532. Only the sound signal is output to the mixer circuit 540. If the received signal is not a streaming signal but a download signal that can be stored in memory, the WiFi wireless communication circuit 515 outputs the processed signal to the signal memory 518 and stores it, and if necessary, from the controller 510. In response to the instruction signal, the signal is read from the signal memory 518 and output as a download signal to the VCA circuit 520 via the D / A converter 519, and only the audible range sound signal via the low-pass filter 532 Is output to the mixer circuit 540. Note that the low-pass filters 531 and 532 output only the audible range sound signal among the input signals by low-pass filtering.

The D / A converters 513, 517, and 519 are, for example, (1) a D / A converter that D / A converts a PCM signal having a sampling frequency of 192 kHz,
(2) a D / A converter that D / A converts a DSD signal having a sampling frequency of 2.8 MHz, or (3) a D / A converter that D / A converts a DSD having a sampling frequency of 5.6 MHz, It is possible to D / A convert not only the audible range but also the super high frequency signal.

  The maximum frequencies of the HD signal and the HS signal are, for example, 88.2 kHz, 96 kHz, 100 kHz, 176.4 kHz, 192 kHz, 200 kHz, 300 kHz, 352.8 kHz, 384 kHz, 500 kHz, 705.6 kHz, 768 kHz, 1 MHz, 1. It is one frequency within a range up to 4 MHz or 2.8 MHz (in the case of a PCM signal, both are maximum frequencies and the sampling frequency is twice these frequencies). That is, the maximum frequency of the HD signal and the HS signal is, for example, one frequency from 88.2 kHz to 2.8 MHz.

Furthermore, the HS signal memory 512 and the signal memory 518 have a large memory capacity of, for example, 64 gigabytes or more, and can store HS signal data that does not include, for example, audio source data. Furthermore, the following data can be stored in the signal memory 518.
(1) Audio source data,
(2) HD signal data not including the HS signal;
(3) HD signal data including HS signals.

  The microphone 509 monitors and detects the ambient sound around the portable player 501 and outputs it to the HS signal level detection circuit 561 via the signal amplifier 511 as a monitor signal. The HS signal level detection circuit 561 extracts a component including the HS signal based on the nature of the autocorrelation order defined in the first embodiment from the input monitor signal, detects the level of the signal, and controls the controller 510. Output to. Specifically, for example, the signal level of the frequency peculiar to the HS signal is detected.

  The VCA circuit 520 mixes each input signal, adjusts and amplifies the level according to an instruction signal from the controller 510, outputs it to the HS signal determination circuit 560, and outputs the built-in actuator 502 and the signal via the signal amplifier 524. Output to the external actuators 503, 504, and 505. The HS signal discriminating circuit 560 discriminates whether or not the HS signal in the input signal is higher than a predetermined threshold level based on the property of the autocorrelation order defined in the first embodiment, and the discrimination result Is output to the controller 510. The VCA circuit 520 detects the signal level of each input signal and outputs it to the controller 510.

  The mixer circuit 540 mixes the input audible sound signals and outputs them to the earphone 506, the built-in speaker 508A, and the external speaker 508B via the signal amplifier 541. Thereby, the audible range sound signal can be radiated to the ears of the auditory system of the user 507 who is a human and can be heard by the user 507.

  The controller 510 includes a keyboard 551 for the user 507 to input operation instructions and operation instructions, a liquid crystal display 552 for displaying display data such as the above instruction results, HS signal discrimination results, HS signal level detection results, and the like. The interface 553 is connected. Here, a USB external device 554 can be connected to the USB interface 553. For example, a USB external device 554 including a nonvolatile memory storing data such as an HS signal, an HD signal, and an audible range sound signal is connected to the USB interface 553. Further, data such as an HS signal, an HD signal, and an audible range sound signal can be stored in the HS signal memory 512 or the signal memory 518 from the USB external device 554 via the USB interface 553 and the controller 510.

The controller 510 controls the operation of each circuit 514, 515, 512, 518, 520, 540 in the portable player 501. Here, when the determination signal from the HS signal determination circuit 560 indicates that the HS signal is not present, the controller 510
(1) The HS signal data stored in the HS signal memory 512 is read to generate the HS signal and output to the VCA circuit 520 via the D / A converter 513, or (2) the HS as a downloaded signal. When the signal data is stored in the signal memory 518, the HS signal data stored in the signal memory 518 is read to generate the HS signal, which is output to the VCA circuit 520 via the D / A converter 519. .
Thus, for example, the output signal from the VCA circuit 520 is always included in the signal output from the VCA circuit 520 while the audible signal is emitted to the ear of the auditory system of the user 507 using the earphone 506 or the like, and the actuators 502 to 505 are included. The vibration of the HS signal can be generated. Therefore, by presenting the vibration to the user 507 and activating the brain, an effect of comprehensively enhancing mental activity and physical activity, that is, a hypersonic effect can be induced.

  In addition, the controller 510 radiates an audible signal to the ear of the auditory system of the user 507 using, for example, the earphone 506 and the detection level is set to a predetermined level based on the detection level from the HS signal level detection circuit 561. When the value is smaller than the threshold value (when the hypersonic effect cannot be introduced), the level of the HS signal input to the VCA circuit 520 is increased so that the detection level exceeds the threshold value. The VCA circuit 520 is controlled. As a result, the signal output from the VCA circuit 520 always includes an HS signal equal to or greater than a predetermined threshold value, and the vibration of the HS signal can be generated by each of the actuators 502 to 505. Therefore, by presenting the vibration to the user 507 and activating the brain, an effect of comprehensively enhancing mental activity and physical activity, that is, a hypersonic effect can be induced.

  Furthermore, the controller 510 controls the VCA circuit 520 so that the levels of the signals that are input to the VCA circuit 520 and mixed are in a predetermined level relationship, for example, substantially the same.

As described above, according to the present embodiment, the following operational effects are obtained.

(2) The HS signal discriminating circuit 560 discriminates whether or not the HS signal is present in the vibration generated by the actuators 502 to 505, and when it does not exist, the HS signal previously stored in the HS signal memory 512 or distributed in advance. Since the HS signal vibration is always generated using the data of the HS signal downloaded and stored in this way, the vibration that can lead to the hypersonic effect can be effectively and reliably presented to the user 507. it can.
(3) The HS signal level detection circuit 561 determines whether or not the signal level of the HS signal is equal to or higher than the threshold value due to vibration in the environmental sound actually generated by the actuators 502 to 505. Since the VCA circuit 520 is controlled to increase the signal level of the HS signal, it is possible to effectively and reliably present to the user the vibration that can lead to the hypersonic effect.
