Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium for .alpha.-wave induction, and more specifically, by reproducing it.
An audible sound that promotes the appearance of α waves in human brain waves α
The present invention relates to a wave guiding recording body.

[0002]

2. Description of the Related Art In human brain waves, β waves (frequency of 18 to 30 hertz) often appear when the mind is tense, and conversely,
When the mind and body relax, alpha waves (frequency 8 to 13 hertz)
Appears continuously. It is said that when the α wave is strong and appears in a wide range, the mind and body of human beings may be at rest, and their ability beyond learning in learning and creative activities may be exhibited.

By the way, in a complicated modern society,
In addition to mental stress such as anxiety, dissatisfaction, anger, and irritation, stress caused by electromagnetic waves radiated from them (so-called techno stress) accompanying the spread of television receivers, video displays, OA equipment, automobiles, trains, etc. Is increasing, without accumulating these stresses,
There is a need for a way to resolve and diverge early. Bathing is the most common method of relieving stress.
A method for relieving static stress such as sleep and rest. This method suppresses the sympathetic nerve and promotes the parasympathetic nerve. However, in such a static stress relieving method, it is generally more effective to apply a stimulus such as sound or vibration to the human body to a comfortable level rather than completely shutting off the stimulus. It turns out that there is.

Under these circumstances, various proposals have hitherto been made for acoustically stimulating the human head for the purpose of reducing the frequency of brain waves.

For example, in Japanese Unexamined Patent Publication No. 50-143377, a brain wave extracted from a subject is amplified once by an electric circuit means, and then the subject hears it through a speaker system or the like to promote the appearance of an α wave. Is proposed.
Further, for example, in Japanese Patent Application Laid-Open No. Sho 56-8037, α waves and θ waves are generated by stimulating sound while switching one or more audible sounds of a subject at a period of 0.05 to 2 seconds.
It has been proposed to induce brain waves such as waves and delta waves.
Further, Japanese Patent Publication No. 22722/1990 discloses about 4 to 1
An electroencephalogram frequency lowering inducing device comprising an oscillator for generating two low-frequency electric signals having a frequency difference of 6 hertz and a sound generating means for converting the low-frequency electric signals into an audible sound including a beat sound having the frequency difference is proposed. Has been done.

[0006] However, the first proposal is that the human α wave has an extremely low frequency of about 8 to 13 Hertz, and it is extremely difficult to convert it into sound with a normal speaker.
Even if it could be converted, such an infrasound is below the lower limit of human hearing, and it is extremely difficult to perceive it as a sound. There is nothing. In the second proposal, although conversion to sound is relatively easy, a relatively short intermittent period, that is, an intermittent period for inducing brain waves such as α waves, θ waves, and δ waves is too short. Since humans cannot easily perceive the presence or absence of discontinuity, it was extremely difficult to induce the desired EEG. The third proposal can promote α waves much more easily than the former two proposals, but has a problem that a special circuit device is indispensable for generating a specific low-frequency electric signal. ..

[0007]

DISCLOSURE OF THE INVENTION The inventors of the present invention have made extensive studies to solve these problems of the prior art.

[0008]

As a result, the inventor
A track for recording a first signal having a frequency of about 130 to 170 Hertz on a magnetic or optical recording medium and a frequency of about 130 having a frequency difference of about 20 Hertz or less with respect to the first signal.
To 170 Hz, a track for recording a second signal is provided, and when an audible sound including a beat sound having a frequency of about 20 Hz or less obtained by reproducing the recording medium is administered to a subject through hearing, it is simple and effective. In the electroencephalogram
It was found that the appearance of waves can be promoted and at the same time the appearance of β waves can be suppressed.

That is, according to the present invention, a track on which a first signal having a frequency of about 130 to 170 hertz is magnetically or optically recorded and a frequency of about 130 to 170 having a frequency difference of about 20 hertz or less with respect to the first signal. The gist of the present invention is a recording medium for .alpha.-wave induction, which has a track on which a second Hertz signal is magnetically or optically recorded and which gives an audible sound including a beat sound having a frequency of about 20 Hertz or less when both tracks are reproduced.

[0010]

The α-wave guiding recording medium according to the present invention gives an audible sound including a beat sound having a frequency of about 20 hertz or less only by reproducing it by a stereo type simple reproducing apparatus. When the audible sound is administered to the subject through hearing, it stimulates the appearance of α-waves in the brain waves and at the same time suppresses the appearance of β-waves.

Hereinafter, the present invention will be described more specifically based on a few examples.

[0012]

[Embodiment 1] In this embodiment, first and second signals giving a beat sound whose appearance frequency and duration change according to the 1 / f fluctuation rule when reproduced are recorded on a compact cassette type magnetic tape. It is a thing.

The electric circuit means for generating such a signal will be described with reference to FIG. 1. In the figure, reference numeral 1 is a microprocessor, inside of which a frequency series storage unit 2 and a duration storage unit 3 are provided. Is provided. That is,
Frequency is 0 to 20 times / min based on a time series of 25 cases with 1 / f fluctuations sampled from α waves of 5 healthy people (3 men in the 20s and 2 women) 5
In terms of stages, the duration is 0 to 60 seconds, which is proportionally divided into 6 stages and stored in the frequency sequence storage unit 2 and the duration storage unit 3. The microprocessor 1 controls the clock pulse from the clock oscillator 4 while referring to the stored contents of both, and generates a pulse train corresponding to the frequency series and the duration series. Since the memory capacity of the microprocessor 1 is limited, the original data can be restored again by referring to a certain number of both the frequency series and the duration series. In this way, a fixed number of pseudo-random signals are obtained. This signal passes through the interface 5 and a low frequency oscillator 6 that oscillates a sine wave with a frequency of 151 hertz as a first signal and a sine wave having a frequency difference of about 20 hertz or less with respect to the first signal as a second signal. They are applied to low-frequency oscillators 6 ′ that oscillate the waves, and the outputs of the low-frequency oscillators 6 and 6 ′ are ON / OFF controlled. The first and second signals thus obtained were recorded on the magnetic tape 8 by the stereo type magnetic recording device 7. At this time, the magnetic tape 8 used was a compact cassette type tape having a tape width of 3.81 mm, and the tape running speed during recording was 4.8 cm / sec. The compact cassette type magnetic tape thus obtained has a track for recording the first signal and a track for recording the second signal, and when reproduced, the frequency is about 2
At 0 Hz or less, an audible sound including a beat sound whose appearance frequency and duration varied according to the 1 / f fluctuation rule was given.

The inventor of the present invention promotes the appearance of α-waves in the electroencephalogram when administered to humans, even when the frequency of appearance, duration, frequency and / or intensity of certain audible sounds is changed by the 1 / f fluctuation rule itself. It was found that there is an action of suppressing the appearance of β waves. In particular, the frequency of occurrence, duration, frequency and / or intensity is observed in biological phenomena in the subject 1
When administering an audible sound including a beat sound that changes according to the / f fluctuation rule, the beat sound and the change in frequency and / or intensity according to the 1 / f fluctuation rule act synergistically, and the 1 / f fluctuation rule It was found that a more remarkable effect was achieved as compared with the case of administering a beat sound without fluctuation due to. This is because a series having 1 / f fluctuations sampled from long-term fluctuations in human biological phenomena contains a lot of important information regarding biological control mechanisms represented by the nervous system, and the information is auditory information. It is understood that when it is administered to human through the above, it effectively acts in addition to promoting the appearance of α-wave and suppressing the appearance of β-wave, and synergistically enhances the physiological action of the beat sound according to the present invention.

In this example, only the appearance frequency and duration of the beat sound are changed according to the 1 / f fluctuation rule, but only one of them is changed according to the 1 / f fluctuation rule, and the other is changed. To change it irregularly,
In addition to the frequency and duration of appearance, the intensity and / or frequency of the beat sound may be changed according to the 1 / f fluctuation rule within a range of more than 0 hertz and not more than about 20 hertz. Further, in the present example, only the example in which the time series sampled from the long-term fluctuation in human α wave is used is specifically mentioned.
Similar experiments were performed on a series sampled from long-term fluctuations in biological phenomena such as blood pressure, respiration, and body temperature, but the results were almost the same, although somewhat inferior to the case of α waves.

[0016]

Example 2 A sine wave having a frequency of 151 Hz is oscillated as a first signal by a low frequency oscillator, and at the same time, another low frequency oscillator provided with a timing circuit and a frequency switching circuit is used as a second signal. 2 for the first signal
Frequencies with a frequency difference of 0 Hertz 141 Hertz, 14
3 hertz, 145 hertz, 147 hertz, 149 hertz, 153 hertz, 155 hertz, 157 hertz, 15
9 Hz and 161 Hz sine waves were oscillated cyclically while switching in this order every minute, and these signals were recorded on a compact cassette type magnetic tape by a stereo type magnetic recording device. A magnetic tape having a tape width of 3.81 mm was used, and the tape running speed during recording was 4.8 cm / sec. The compact cassette type magnetic tape thus obtained has a track for recording a first signal and a track for recording a second signal, and when both tracks are reproduced,
An audible sound including a beat sound having a frequency of about 20 hertz or less was given.

In the above embodiment, the embodiment in which the first and second signals are magnetically recorded on the magnetic tape of the compact cassette type has been described, but it goes without saying that the present invention is not limited to this. As a magnetic recording medium, in addition to a compact cassette type magnetic tape, for example, a video tape, a digital audio tape,
Magnetic disks, magnetic floppies, etc., and optical recording bodies such as compact disks and video
It is needless to say that an optical disk such as a disk can be used, and even if the first and second signals optically recorded on these are reproduced, an audible sound including a beat sound having a frequency of about 20 hertz or less is given when reproduced. Yes.

As a result of various experiments conducted by the present inventors on the waveforms of the first and second signals, the best results were obtained when the first and second signals were sinusoidal waveforms. However, the present invention is not limited to this, and the frequency is in the range of about 130 to 170 hertz, and the audible sound including the beat sound having a frequency of about 20 hertz or less is reproduced, and the audible sound is A waveform other than a sine wave may be used, if necessary, as long as it is administered to humans to promote the appearance of α waves. For example, the waveforms of the first and second signals having a sine wave waveform may be changed by a waveform synthesizing circuit, a modulation circuit, or the like within a range in which the intended effect is not lost.

The frequency of the first and second signals used in the present invention is about 130 to 170 hertz, preferably about 140 to 160 hertz, and more preferably, about 140 to 160 hertz.
The reason for limiting to about 150 to 155 Hz is that the audible sound in the frequency range is administered to many subjects to consistently strongly promote the appearance of α-waves and suppresses the appearance of β-waves. .. Although its providence in the human body has not yet been elucidated, when an audible sound with a frequency below or above this range is administered to a subject, even if the frequency of the beat sound generated at that time is about 20 hertz or less, it is frustrating. There were cases of complaining of discomfort, arousal or insomnia. When the electroencephalogram at that time was examined, not only was there no significant improvement in the appearance of β-waves or the intensity, distribution, and continuity of α-waves, which is peculiar to the present invention, but on the contrary, the distribution of β-waves was wide,
The distribution of alpha waves was narrow, weak, and discontinuous at the same time as being strong and continuous. Based on these experimental results, the above range was made the best.

Next, the method of using the present invention will be described by taking the recording medium of the embodiment as an example. Since the recording body of the embodiment using the compact cassette type magnetic tape is small and easy to carry, it can be used for various purposes.
For example, the recording medium according to the embodiment is loaded into a portable stereo cassette tape reproducing device, and stereo headphones are attached to both ears of the subject. When the recording medium is reproduced in this state, the first signal and the second signal recorded on the recording medium are reproduced on the stereo headphones, and the frequency generated by the interaction of these signals through the auditory sense of the subject. Audible sounds are administered, including beat sounds of about 20 hertz or less. As a result, the appearance of α-waves in the electroencephalogram of the subject is promoted and at the same time the appearance of β-waves is suppressed, so that the mind and body of the subject relax and shift to a resting state.

From the above, the recording material of the present invention is not limited to the resting of the mind and body, improvement of learning ability and creative ability. For example, neurosis, mental dementia, psychosomatic disorder, manic depression, chronic Mental illness such as alcoholism, and thinking power due to general stress including techno-stress caused by electromagnetic waves emitted from, for example, television sets, video displays, OA devices, automobile spark plugs, trains, etc.,
It exerts a special effect in reducing or relieving concentration, decreased work motivation, insomnia, malaise, intimidation, phobia, and deficiency. Therefore, the recording material of the present invention can be
At schools, cram schools, driving schools, training centers, research laboratories, ateliers, etc., as a means to enhance learning ability, academic research ability, and creative ability, and at work, clinics, hospitals, sanatoriums, etc. It is useful as a means for preventing and treating various mental disorders. At this time, although depending on the purpose of use, the method of administering the audible sound according to the present invention is to be slightly strong at the beginning and gradually weaken. When the purpose of use is to improve learning ability and creativity, it may be administered each time as needed. On the other hand, for the purpose of prevention and treatment, while carefully observing the condition of the subject, for example, 1 It may be administered 1 to 3 times daily, up to about 2 hours per administration for 1 to 7 days every week, 1 month to 1 year.

Next, the function and effect of the present invention will be described based on a few experimental examples.

[0023]

[Experimental Example 1] Eight healthy persons aged 25 to 51 (4 males)
Subjects, 4 females), and their heads were equipped with stereo headphones and a biomedical electrode for EEG measurement according to the "International Electroencephalographic Society Standard Electrode Arrangement Method". A brain waveform connected to a data processing device was connected to the biomedical electrode for measuring brain waves, and a stereo cassette tape reproducing device in which the recording medium according to Example 1 was loaded was connected to the stereo headphones.
In this state, the subject was first subjected to the Kleppelin test (continuous first place addition work) for 30 minutes. Immediately after completion of the Kleppelin test, sit in an easy chair for renal dialysis in a state where it is as relaxed as possible, close your eyes, and use the left and right speaker units of the stereo headphones to output two types of audible sound with a frequency difference of about 2 to 26 hertz or less. Was administered. At this time, the beat sound generated was strong at the beginning, and was gradually weakened for 5 minutes. A clinical laboratory technician was involved in the experiment, and the clinical laboratory technician performed P3 on the subject's head immediately after the end of the Kreppellin test and immediately after the administration of the beat sound.
And β wave from the electrodes attached at the positions of P4 and 01
Α-waves were derived from the electrodes mounted at positions 0 and 02 by the unipolar derivation method. With respect to the derived electroencephalogram, the waveform of each electroencephalogram component was examined by an electroencephalograph, and frequency analysis was performed for each component by an attached data processing device, and then the amplitude (microvolt) was measured.

As a control, after completion of the Kreppelin test,
Treat the subject in the same manner as above except that the subject was allowed to rest for 5 minutes with their eyes closed, and only the stereo headphones were worn and no beat sound was administered, or the sound of the same frequency was administered from the left and right speaker units of the stereo headphones. A treatment system similar to that described above was provided.

After the above experimental work was completed, the percentage (%) of the amplitude of the α-wave or β-wave immediately after the administration of the beat sound with respect to the amplitude of the α-wave or β-wave immediately after the end of the Kreppellin test was obtained for each subject. , It was used as a standard for promoting the appearance of α-waves and suppressing the appearance of β-waves by administration of beat sounds. Table 1 shows the average value of 8 healthy persons. 2 and 3 are topographs of electroencephalograms measured immediately after the end of the Kreppellin test and immediately after the administration of the beat sound of one of the healthy persons who participated in this experiment, and the beat sound was administered. This is for determining how the intensity and distribution of the α-wave have changed.

[0026]

[Table 1]

As is clear from the results shown in Table 1, when an audible sound including a beat sound with a frequency of about 20 hertz or less was administered to a healthy person, when no audible sound was administered, an audible sound without a beat sound was administered. , Or the intensity of α-waves in brain waves is increased to about 160 to 230%, while the intensity of β-waves is about 10 to 10%, as compared with the case where audible sounds including beat sounds exceeding about 20 hertz are administered. It was suppressed to 50%.
Further, according to the electroencephalogram observation, when the beat sound according to the present invention is administered, a clear improvement is observed in the continuity of the α-wave in the electroencephalogram, and it is clear that the subject's mind and body are well relaxed. Became. The state of the electroencephalogram at this time will be described based on the electroencephalogram of one of the subjects. As shown in FIG. 2 (a), the α wave immediately after the end of the Kleppellin test is generally weak and its distribution is relatively limited. Although it appeared in the region where it was given, immediately after the administration of the beat sound, it was strongly and widely distributed around the parietal region. Regarding β waves, immediately after the end of the Creppelin test, what was more dominant than α waves was significantly suppressed by the administration of the beat sound.

In addition to the sine wave having the frequency of 151 hertz as the first signal, the same experiment was conducted for the frequency of 100 to 200 hertz, and the frequency of the first signal was in the range of about 150 to 155 hertz. Similar results were obtained when the frequency of the second signal was in the range of about 130 to 170 Hertz. If the beat sound does not change according to the 1 / f fluctuation rule, or
The frequency of the first or second signal is about 130 Hz or more and about 1
If the frequency is less than 50 hertz or more than about 155 hertz and less than about 170 hertz, the above result is slightly inferior, but α
A remarkable effect was obtained in promoting the appearance of waves and suppressing the appearance of β waves. On the other hand, the frequency of the first and / or second signal is about 13
Below 0 hertz or above, even if the waveforms of the first and second signals are sinusoidal, even if the frequency difference of the second signal with respect to the first signal is about 20 hertz or less, In addition to the above results, there were frequent cases of complaining of irritation, discomfort, arousal or insomnia.

The above results show that the frequency according to the present invention is about 2
Approximately 130 to 17 frequencies including beats below 0 Hz
This fact supports the fact that the administration of 0 Hz audible sound through human hearing is very effective in suppressing the appearance of β-waves in brain waves, promoting the appearance of α-waves, and improving continuity.

[0030]

Was selected, and an audible sound including a beat sound having a frequency of about 20 Hz by the recording medium shown in Example 1 was administered through hearing. The disease names of the individual subjects were neurosis, neurasthenia, insomnia, stress, etc. All the diseases were chronic, and in addition to medication, injection, low-frequency treatment, etc., he had been continuously undergoing special psychiatric treatment such as psychotherapy and sleep therapy.

The treatment was carried out by the subject himself or herself under the guidance of a doctor, and the subject was placed on a bed or an easy chair in a state of being relaxed as much as possible, and an audible sound including a beat sound of the above frequency was administered. At that time, it was strong at first and gradually weakened. The administration was carried out once to three times a day, daily or two to four times a week for about one month while observing the condition of the subject. The administration time was about 15 minutes to 1 hour per treatment and a maximum of 2 hours. Also, during treatment, observe the subject's EEG changes by the method of the experimental example, if necessary,
After the treatment, the doctor asked about the treatment effect and side effects. The therapeutic effect is judged by a four-level evaluation of "well worked", "somewhat worked", "unchanged", and "worse", and is judged as "well worked" or "somewhat worked" The cure rate (%) was defined as the percentage of the persons. The results are shown in Table 2.
