{Anti-Snoring Device Capable Of Stopping Selectively User`s Snoring Out Of A Plurality Of Snoring Sounds}

The present invention relates to a snoring prevention device, and more particularly, even if more than one person sleeps in the same space, by determining whether a specific user snoring during sleep or apnea during snoring, It relates to a snoring prevention device capable of stopping snoring by selecting a user from among a plurality of snoring sounds that enable the user to stop snoring or apnea during sleep by allowing the user to awaken the user's sleep.

Until now, the snoring prevention device that can stop snoring by selecting a user from among the majority of snoring is, for example, registered utility model No. 20-0475814 (automated snoring prevention bed system). It is designed to include at least one or more sensing parts mounted to contact a part of the body, so that various signals generated from the human body are detected through the above parts, or the snoring sound is directly received to determine whether the user is snoring. .

However, the above snoring prevention device determines whether snoring is being measured, that is, by using a sensing part for each individual user, or by receiving a snoring sound while sleeping alone in an independent space. .

Therefore, in order to determine snoring, the conventional snoring prevention device necessarily requires an individual device for measuring snoring, so the unit cost of the entire device is increased, and in order to use it, it is necessary to wear it on a specific part of the human body. There was a problem to follow.

In addition, in the case of determining whether the user is snoring by receiving the snoring sound directly through the receiving device, the user's snoring sound cannot be discriminated when another person sleeps at the same time in the defined space where the user sleeps. In addition to causing discomfort, there is a problem in that the accuracy of snoring judgment is greatly degraded due to noise generated inside and outside the defined space even when sleeping alone.

KR 20-0475814

The present invention has been proposed to solve the problem of the conventional snoring prevention device as described above, and without using any type of parts or devices that are directly worn on the user's body to determine whether snoring or not, snoring In the defined space in which this measurement is made, it is possible to determine whether the user's snoring or sleep apnea following snoring, even if a number of people other than the user sleep as a control group at the same time, thereby enhancing the usability of the snoring prevention device and improving the snoring. Its purpose is to improve the accuracy of judgment as to whether this or sleep apnea.

In order to achieve this object, the present invention compares one or more snoring sounds sampled from a sound source composed of a user alone or composed of a user and one or more control groups, that is, a sound received in real time during operation, and compared with the measured sound, the measured sound A portable terminal that determines whether or not the target sound generated by the user is included; And an awakening operation means for awakening the user's sleep when the measured sound is the target sound as a result of the determination by the portable terminal, wherein the portable terminal comprises the snoring sound from the sound source.

It is preferably made.

In addition, when the number of sound sources is n, the synthesizer synthesizes the snoring sound from different sound sources so that it becomes the second to nth order over _n C ₂ to _n C _n times to generate the synthesized sound. It is desirable.

In addition, if the number of the sound sources is n, the order of the snoring sound and the synthesized sound is determined whether the net audible sound excluding the existing sound from the measured sound is the snoring sound and the synthesized sound when the measured sound increases by more than the reference pressure. According to a maximum of _n C _{1 to n} times to be compared, and when the measured sound is not the snoring sound and the synthesized sound, it is preferable to determine it as noise.

In addition, it is preferable that the determination unit determines that the user is snoring when the pure jeungeum i includes the target sound as a result of comparing the pure jeungeum with the snoring and the synthesized sound.

In addition, it is preferable to include a user detection means for checking whether the user is present in the sleeping position.

In addition, the discrimination unit assumes that the number of sound sources is n, and when the measured sound decreases by more than the reference pressure, the target sound in the snoring sound and the synthesized sound assuming that the target sound is excluded from the pre-voiced sound. but the match net negative minus comparison whether the snoring joint, and up to _n-1 C _{1 to n-1} times in accordance with the order of the synthesized voice that the net negative because subtracting the target sound at the snoring joints and the polyphonic When the order is reduced to n-1, when n is 1, that is, when the order is 0, the voiced sound and the target sound are not compared, and when the additive or subtractive sound does not coincide with the subtractive sound, the ready-made sound It is preferable to determine that the net attenuated sound minus the measured sound from the sound is noise.

In addition, the determination unit is the target sound, which is assumed to be excluded when obtaining the additive or subtractive sound when the result of comparing the subtractive sound and the subtractive sound is the true target sound, so that the target sound is the target sound. Therefore, if the user detection means checks whether the user is in the current sleeping position, and as a result, it is determined that the user is in the current sleeping position, the user determines that it is a sleep apnea state following snoring. desirable.

In addition, it is preferable that the snoring determination module samples the corresponding snoring sound from false snoring made while one of the user and the control group is awake.

In addition, the awakening operation means is made of a speaker mounted on one side of the mattress of the bed, and the speaker transmits vibration to the user through the mattress and stimulates the user's sleep when a user sleeping on the mattress snores. It is desirable to awaken.

In addition, the awakening operation means is made of an actuator mounted on one side of the foldable bed, and the actuator stimulates the user by rotating one side of the bed relative to the other side when a user sleeping on the foldable bed snores. It is desirable to awaken the sleep of.

In addition, the present invention is another embodiment, compared to the one or more teeth sampled from a sound source consisting of a user and one or more control groups, that is, the actual sound received in real time during operation, the measured sound from the user A portable terminal that determines whether or not the generated target sound is included; And an awakening operation means for awakening the user's sleep when the measured sound is the target sound as a result of the determination by the portable terminal, wherein the portable terminal It provides a snoring prevention device capable of stopping snoring by selecting a user from among a plurality of snoring sounds including a lice determination module configured to independently sample lice.

Hereinafter, a snoring prevention device capable of stopping snoring by selecting a user from among a plurality of snoring sounds according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown by reference numeral 1 in FIGS. 1 and 2, the snoring prevention apparatus of the present invention comprises a portable terminal 3 and an awakening operation means 5 largely.

Here, the portable terminal 3 is a small device that the user can carry, such as a typical mobile phone. In addition to the call function, the mobile terminal 3 is a basic configuration related to data storage and communication such as a control unit, a memory, and a wireless communication unit, as well as signal transmission/reception and input/output. It means a device that includes additional components such as a microphone, a recorder, and a speaker.

Therefore, in this embodiment, the portable terminal 3 collects and stores the snoring sound, and compares the collected snoring sound with the measured sound measured during sleep to find the user's snoring sound, that is, the target sound (T). Plays a role. At this time, the comparison of the snoring sound sampled for collection and the measured sound can be made through various factors such as loudness, pitch, or tone, but is not affected by the phase difference of the sound wave, and is compared through the tone determined according to the waveform. It is desirable. However, since the tone is affected by the overtone, it is desirable to match the condition of the overtone generation when comparing the snoring sound sampled through the tone and the measured sound. Accordingly, it is important to ensure that the portable terminal 3 and the user are in the same position as will be described later when sampling the snoring sound and when performing the actual measurement.

To this end, the portable terminal 3 is a communication unit 11, a microphone 13, a display 15, a memory 17, an awakening operation unit 19, a user detection unit 20, as shown in FIG. , And a control unit 21 and the like.

Here, first, the communication unit 11 is awakened by connecting the awakening operation unit 19 and the awakening operation means 5, or the user detection unit 20 and the user detection means 7 respectively by wired or wireless communication in the present invention. It is a part that transmits and receives various signals with the operation means 5 or the user detection means 7, and in most cases, in recent years, with the development of communication technology, a large amount of digital data is transmitted through a wide spectrum frequency at low power in a short distance section. Ultra-wideband wireless technology for transmitting and receiving is adopted. Therefore, the communication unit 11 operates the awakening operation means 5 through the awakening operation unit 19 according to the command of the control unit 21, and the result is returned to the control unit 21 through the awakening operation unit 19. Give feedback. In addition, the communication unit 11 transmits the detection result of the user detection means 7 to the control unit 21 through the user detection unit 20.

The microphone 13 is built into or connected to the portable terminal 3, like a general microphone used in a mobile phone, and is used for making a phone call or voice recording. In particular, in the present invention, the microphone 13 records and samples snoring sound from various sound sources such as the control as well as the user through the audio unit 23 according to the command of the control unit 21, or the snoring prevention device 1 is operated. After that, it plays a role of acquiring in real time various sounds generated in the surroundings, including the snoring sound of the control group consisting of more than one person, that is, the measured sound. At this time, the control group refers to another person who sleeps together in the designated space when the designated space in which the user sleeps is referred to as the designated space. For example, if the sleeping space is the couple's bedroom, the control group will be a spouse.

The display 15 is a display device such as a general liquid crystal display device of a mobile phone, and provides a screen for performing basic mobile phone functions such as a keypad screen or a screen for video calls, as well as other video screens for learning or entertainment. In the present invention, it also serves as an interface connecting the user and the control unit 21 through the display unit 25. That is, the display 15 implements various screens for executing and ending the snoring prevention device 1 through a separate app provided in the form of an icon.

The memory 17 is a storage device such as a general memory used in a mobile phone, and stores various data. In particular, in the present invention, as well as storing the snoring sound sampled from the user and the control group, the snoring prevention device 1 It serves to store various sounds input through the microphone 13 while is being used.

The awakening operation unit 19 is a part that controls the operation of the awakening operation means 5 according to the command of the control unit 21, and serves to start, end, or stop the operation of the awakening operation means 5.

The user detection unit 20 is a component added in another embodiment of the present invention, and serves to transmit a user presence/absence signal sensed by the user detection means 7 to the control unit 21.

The control unit 21 is a part that controls all elements of the mobile terminal 3 ranging from the communication unit 11 to the awakening operation unit 19 or the user detection unit 20 mentioned above, and points to the integrated CPU and the GPU. , In some cases, a communication unit 11 may be included. Accordingly, the control unit 21 of the present invention compares the snoring sound sampled through the microphone 13 and stored in the memory 17 with the measured sound I input in real time through the microphone 13 during use. , It is determined whether the measured sound (I) contains the target sound (T) generated from the user, and when the measured sound (I) includes the target sound (T), awakening through the awakening operation unit 19 The operation means 5 is operated to awaken the sleeping user to stop snoring. Or, when the actual sound (D) is smaller than the pre-existing sound (F) in the demarcation space before waiting for the reception of the measured sound, the addition or subtraction sound (assuming that the target sound (T) is excluded from the pre-voiced sound (F)) U) is compared with the snoring sound and the subtractive sound (-S) by subtracting the target sound (T) from the synthesized sound (S), and checks whether the user's sleep apnea is confirmed, and if apnea is confirmed accordingly Awakening the sleeping user to stop sleep apnea. However, on the contrary, when determining whether sleep apnea or not, the control unit 21 first finds the user, that is, the target sound (T), and then tracks and monitors the respiration cycle of the found target sound (T), and the target sound (T) is At the same time, when it is confirmed that the user is in the sleeping position, it may be determined that the user is in a sleep apnea state following snoring.

In particular, as shown in Figure 2, the control unit 21 includes a snoring determination module 27, the snoring determination module 27 to determine the sleep apnea following the snoring or snoring generated by the user To do this, each snoring sound is independently sampled from a sound source consisting of a user as well as a control group. To this end, the snoring determination module 27 again includes a synthesis stage 31 and a determination stage 33. First, the synthesis stage 31 is a snoring sound sampled from a user and a control group, that is, from a sound source. This part is synthesized so that it can be compared with the actual sound. Before the monitoring by the snoring prevention device 1 starts, all snoring sounds sampled from the sound source are selectively synthesized to create a synthesized sound. At this time, it is preferable to sample all snoring while maintaining the same distance or conditions as when actually measured. That is, for example, when the user alone sleeps in the above defined space, there is no room for synthesis because there is only one sound source, and the user's snoring sound is recorded by placing the mobile terminal 3 in a location adjacent to the user. Sample. At this time, since the user is not sleeping, in order to sample the user's snoring sound, place the portable terminal 3 at a position where it is placed while sleeping, and record, but when the user is awake, for example, lying down and snoring with false voice. If you create and record, you can sample more conveniently. However, if the actual snoring sound is recorded and sampled while sleeping, the sampling result can be obtained more precisely, but it is relatively cumbersome. At this time, since the snoring sound occurs not only in inhalation but also in exhalation, the snoring sound of inhalation and exhalation is made during sampling, and both are sampled as snoring sounds of one user.

In addition, when the user couple sleeps together in the above demarcation space, since there are two sound sources, the sound that can be made in the demarcation space is the user snoring sound T, the spouse, that is, the control snoring sound A, T and The two snoring sounds of A and 1 synthesized sound of TA are combined to make a total of 3. At this time, the sampling of the spouse, that is, the control group, as in the case of the user alone, may be achieved by recording the false snoring sound of the control group through a portable terminal 3 placed in a position to be put during sleep, or each control group sleeps alone. It can also be achieved by recording the actual snoring sound in the state. Moreover, when there is a sound received, except for the snoring sound and its synthesized sound sampled from the user and the control group, the entire sound is viewed as another control group and the target sound is determined.

In addition, the determination unit 33 compares the snoring sound and the synthesized sound generated from the sound source with the measured sound (I,D) measured by the portable terminal 3 as described above, and determines whether or not they match. When the resultant measured sound matches the target sound T or the synthesized sound including the target sound T, it is determined that the current user is snoring, and the awakening operation means 5 is operated. However, since it is difficult to accurately match the snoring sound and the synthesized sound (S) and the measured sound (I,D), which is a combination of these sounds, the accuracy of the snoring sound and the synthesized sound is determined with an error range of 10 to 20% for the measured sound. It is desirable to judge.

On the other hand, the awakening operation means 5 is a means for directly awakening a sleeping user to stop snoring, and various devices can be employed. For example, as shown in FIG. 1, a speaker 51 or an actuator 53 Can be used as the awakening operation means (5). In the case of employing the speaker 51 as the awakening operation means 5, the speaker 51 is mounted on the side or bottom of the air mattress AM, as in the vibration system disclosed in Patent No. 10-0684071 of the present applicant. Thus, by generating vibration in the air mattress AM according to the instruction of the awakening operation unit 19, it is possible to stop snoring by stimulating and awakening the user who is snoring during sleep. However, it is preferable that the speaker 51 can be set to a predetermined intensity by varying the intensity of the vibration. In order not to interfere with the detection of snoring, the speaker 51 only vibrates but does not generate sound.

In addition, the actuator 53 is mounted on the joint portion (J) of the folding frame (F) supporting the folding mattress (BM) of the folding bed (B), as shown in FIG. According to one end of the folding mattress (BM), in particular, by lifting by rotating the head side, it is also possible to stop snoring by stimulating the user's sleep.

In addition, the user detection means 7 is a pressure sensing device installed on a bed or the like to check whether the user is in the current sleeping position, and the user can check whether the user is in sleep apnea following snoring during sleep. It is used in other embodiments of the invention. Therefore, the user detection means 7 is, for example, in the case of the vibration system disclosed in the above Patent Registration No. 10-0684071 shown in Fig. 1, although not disclosed in the publication, the air compressor (C) and the air mattress (AM) By utilizing the pressure sensor installed on the pipe line of the hose (H) connecting to the user detection means (7), it is possible to detect the change in the load applied to the mattress (AM), and thus whether the user is located on the mattress (AM). Whether or not it can be checked through the change in load. That is, when the user lies on the mattress AM and the load increases, the internal pressure of the mattress AM increases, so the control unit 21 detects this through the pressure sensor to confirm that the user is on the mattress AM. In other cases, when the user detection means 7 is applied to the foldable mattress BM of the foldable bed B shown in FIG. 1, it may be mounted and used on the bottom of the mattress BM. In this case, a thin plate-type load cell, etc. may be employed as the user detection means 7, and therefore, of course, the presence or absence of a user on the foldable mattress BM can be confirmed through a pressure change sensed by the user detection means 7. .

In addition, the system 1 of the present invention can cause the user to stop the lice by awakening the user's sleep in the same manner as above by replacing the snoring sound with the lice sound. To this end, the system (1) uses a mobile terminal to sample each tooth gap from a sound source consisting of a user and a control group of at least one person. At this time, sampling for each sound source consisting of a user and a control group is performed by false voice while awake. Because it is difficult to make, it is recommended to independently record individual teething noises during sleep while sleeping for sampling. As described above, the rest of the matters related to teething prevention are the same as when snoring is prevented, so a detailed description will be omitted.

Now, the operation of the snoring prevention device 1 capable of stopping snoring by selecting a user from among a plurality of snoring sounds according to a preferred embodiment of the present invention will be described as follows.

In order to prevent snoring using the snoring prevention device 1 of the present invention, first, as shown in FIG. 3, the power switch of the snoring prevention device 1 is turned on (S10).

Accordingly, the snoring determination module 27 samples and synthesizes the snoring sound from all sound sources including the user (S20). To this end, as described above, the mobile terminal 3 is placed in the location where the user sleeps, that is, the storage location, and the snoring sound produced by the false voices of inhalation and exhalation by the user and the control group is used by the microphone 13. Through individual recordings, that is, alone or by recording the actual snoring sound individually, each snoring sound is sampled. However, when recording a false snoring sound, it is desirable for the user and the control group to record at the location where they normally go to bed in the designated space where sampling is performed. In this way, when the sampling of the snoring sound is completed, the snoring determination module 27 selectively erases and synthesizes the snoring sound sampled in the synthesis stage 31 to create a synthesized sound. At this time, the number of sound sources is 1 to If it is n, the number of sampled snoring sounds (S) is S ₁ to S _n . That is, including the target sound (T), which is the user's snoring, if the control group is 3, there are a total of 4 snoring sounds (T, A, B, C), and these snoring sounds are 2nd to nth order. If possible, samples sampled from different sound sources are _{synthesized over n} C ₂ to _n C _n times to generate a synthesized sound. _{That is, for example, by synthesizing 4} snoring sounds T, A, B, and C so that the order becomes 2nd order 4 C ₂ =6 times, a total of 6 synthesized sounds are generated. do. _{Synthesized tones 4} C ₃ = 4 times to be of the 3rd order generate a total of 4 synthesized tones: TAB, TAC, TBC, and ABC. Lastly, only one TABC is produced for the synthesized sound ₄ C4 = 1 times to be of 4th order. However, when sampling a snoring sound from a sound source, if the sampling position is matched with the position at which each sound source sleeps during sleep, each snoring sound also matches the snoring sound and overtones generated during sleep.

Then, the snoring determination module 27 may convert the frequency of the snoring sound and the synthesized sound by FFT as necessary (S30).

Then, before entering the reception standby mode, the snoring determination module 27 checks whether or not a valid sound having a predetermined pressure or higher already exists in the defined space, and if so, converts it to a frequency as necessary (S40).

When the preparation for operation is completed in this way, the user puts the portable terminal 3 in the storage position and enters the surface, and goes to bed at his sleeping position designated as a control group. The portable terminal 3 waits for any sound to be received (S50).

Eventually, when a meaningful sound having a sound pressure higher than the reference pressure is captured through the microphone 13, the increased sound signal, that is, the measured sound (I) can be frequency converted through FFT, and the measured sound (I) Subtract the above voiced sound (F) from and obtain the net augmented sound (Ri) (S60).

Then, the snoring determination module 27 compares the pure sound Ri with the snoring sound and the synthesized sound through the determination unit 33 (S70). For this, first, it is determined whether each snoring sound having the first order, for example, T, A, B, C sampled from four sound sources including the user above, matches the four snoring sound (Ri) at maximum _n C. It compares _once (S71). At this time, since n is 4, it is checked whether the net sound (Ri) and the snoring sound are matched over a _{maximum of 4} C _{1 =4 times.} That is, it checks whether Ri=T?, Ri=A?, Ri=B?, Ri=C?.

As a result of checking, if the net augmentation (Ri) matches the target sound (T) of the snoring with Ri = T, since the net augmentation (Ri) is derived from the user, the awakening operation means ( By operating 5) (S80), by stimulating the sleeping user, the user's snoring is stopped.

Thereafter, if the snoring prevention device 1 is in operation, the snoring determination module 27 waits for the reception of the sound again, and if not in operation, a series of snoring prevention routines are terminated.

On the other hand, as a result of the comparison in the above step (S71), if it is confirmed that the net augmentation Ri does not have the first order, as the next step, the net augmentation Ri is compared with the synthesized sound having the second order (S72). ). That is, each synthesized sound having a second order of pure augmentation (Ri), for example, T, A, B, C, sampled from four sound sources including the user as above, and selectively synthesized with other snoring sounds. The formed synthesized sound is _{compared up to n} C ₂ times (S72). That is, for example, whether or not the six synthesized sounds of TA, TB, TC, AB, AC, and BC match with each other is compared over a _{maximum of 4} C _{2 =6 times.}

As a result of the comparison, if it is confirmed that the net augmented sound (Ri) is any one of the synthesized sound including the target sound (T), that is, TA, TB, and TC, the user is snoring as well, so the awakening operation unit 19 is immediately activated. By operating the awakening means 5 through (S80), by stimulating the sleeping user, the user's snoring is stopped.

When this process is generalized, the snoring determination module 27 compares the net augmented sound Ri with the synthesized sound having the nth order at most _n C _n =1 times (S7n). That is, when there are 4 sound sources as above _{, the net augmentation (Ri) is compared with the synthesized sound TABC over n} C _n = 1 time. Since the nth synthesized sound unconditionally contains the target sound (T), the net augmentation (Ri If) coincides with the n-th synthesized sound, the awakening operation means (5) can be immediately operated without checking whether the target sound (T) is included in the net augmented sound (Ri) (S80), and even in this case, the user To stop snoring.

However, if the net augmented sound (Ri) and the n-th synthesized sound do not match, the net augmented sound (Ri) is not a sound generated from the sound source, so it is defined as noise (N) (S90), and the snoring prevention device (1) is again Enters the standby mode for sound reception (S50). However, before that, it is checked in advance whether or not there is a voiced sound F, and if there is, frequency conversion is performed (S40).

Thereafter, if a significant sound having a sound pressure higher than the standard pressure is added to the noise (N) that has been continuously received as the pre-voiced sound (F) and a change occurs, the net augmented sound (Ri) is similarly obtained (S60), and the above process (S70) is performed. If repeated again, it is possible to continuously prevent snoring of the user while the snoring prevention device 1 is operated, and if not in operation, the series of snoring prevention routines as described above are terminated.

In addition, although a detailed description is omitted, the user's sleep can be awakened in the same manner as above through the user's lice sound, and the lice can be stopped.

On the other hand, according to another embodiment of the present invention that can prevent not only snoring, but also sleep apnea following snoring, as shown in FIG. 4, the power switch is turned on (S10), and the sampling of the snoring sound and formation of a synthesized sound (S20), frequency conversion of the sampled sound as needed (S30), check whether there is a voiced sound (F) (S40), wait for the reception of the sound (S50), and when the measured sound (I) is received After subtracting the pre-voiced sound (F) from the measured sound (I) to obtain the net augmented sound (Ri) (S60), by comparing the pure augmented sound (Ri) with the snoring and synthesized sound (S70), targeting the pure augmented sound (Ri) When the sound (T) is included, a series of snoring prevention routines for stopping the user's snoring by performing a sleep awakening operation (S80) are performed in the same manner as in the embodiment of FIG. 3.

However, while waiting for the reception of sound (S50), if the received sound, that is, the measured sound, is the same as the pre-voiced sound (F), as shown in FIG. 5, the signal reception is waited after checking the pre-voiced sound (F) again, If the sound received in the air (S50), that is, the measured sound (D) is significantly reduced to more than the standard pressure than the pre-voiced sound (F), frequency conversion of the reduced measured sound (D) if necessary, and then the snoring determination module In step (27), it is determined whether the target sound T is erased using the reduced sound signal, that is, the measured sound D (S100).

That is, in the above step (S100), the determination unit 33 first obtains the subtracted additive (U) by assuming that the target sound (T) has been erased from the pre-voiced sound (F) checked in step (S40) (S100). Next, before comparing the subtractive sound (U) with the synthesized sound (S), the subtractive sound (-S) obtained by subtracting the target sound (T) from the synthesized sound (S) is obtained (S110). At this time, for example, if the sound source is T, A, B, C, D, n is 5, and for the composite sound of the second order, 10 of TA, TB, TC, TD, AB, AC, AD, BC, BD, and CD are generated. do. There are four synthesized sounds including the target sound (T), TA, TB, TC, and TD. Since the additive sound (U) is the primary target sound (T) minus the target sound (T) in the subtractive sound (-S). ) Is subtracted, and thus the order of the subtractive sound (-S) decreases by 1 compared to the synthesized sound (S). For example, the synthesized sounds TA, TB, TC, and TD are A, B, C, and D. On the other hand, if the target sound (T) is subtracted from AB, AC, AD, BC, BD, and CD, the sound is different from A, B, C, and D, so A, B, C It can be seen that it does not match with D. Therefore, when comparing the subtractive sound (U) and the subtractive sound (-S) for the first time, the order of the subtractive sound (-S) becomes the first order, and is expressed as _{U = -S 1 ?.} And, the maximum number of comparisons is _n-1 C ₁ = ₄ C ₁ = 4 times.

In this way, in order to determine whether the erased sound is the target sound (T) when the unknown sound, that is, the net attenuation sound (Rd) is erased from the pre-voiced sound (F) and the measured sound (D) is reduced (S120 ), the target sound (U), assuming that the target sound (T) is subtracted from the pre-voiced sound (F), and the subtractive sound (-S) whose order is reduced by 1 by subtracting the target sound (T) from the synthesized sound (S). (T) comparing the maximum _n-1 C ₁ once only that contains, can determine whether the synthesized (S) among whether the target sound (T) from the second car erase the notes. That is, if, for example, the subtractive sound (-S) A from which the target sound (T) is removed from TA, which is a subtractive sound (U) and a synthesized sound (S), is compared and matched, the pre-voiced sound (F) is TA, and thus the pre-voiced sound ( It is confirmed that the assumption of the addition and subtraction sound U, which is the target sound T, that is erased in the process of F) becoming the measured sound D is true (S121). In this case, next, if the user is in the sleep position and is detected (S130), the user is in the sleep position and the snoring has stopped, so it is determined as sleep apnea, and the user performs a sleep awakening operation through the awakening operation means (5). It is possible to stop the apnea (S140). However, if the user is not detected, as shown in FIG. 4, the presence or absence of a pre-voiced sound is checked (S40), and reception standby is entered (S50).

Acceleration in the same way sound (U) = net negative (-S) and whether the maximum _n-1 C ₁ That is to compare time, U = A, B, C, D results confirm whether over a maximum of four times, matching If is not obtained, since none of the subtractive sounds (-S ₁ ) with the order of 1 lowered by the first order match with the addition and subtract sounds (U), the next step is to add _{or subtract from the subtractive sound (-S 2) with the order of 2} It is checked whether there is any coincidence with the negative (U) (S122).

In the same manner, it is checked whether there is a match between the final subtractive sound (-S _n-1 ) and the subtractive sound (U) (S12n). At this time, the final subtraction sound (-S _n-1 ) is n-1 since the order is lowered by one from n. _{As a result, if there is a subtractive sound (-S n-1} ) that matches the additive sound (U) as above, you can stop sleep apnea following the snoring in the same way as above (S140), and if a matched result does not come out, The net attenuation (Rd) is determined as noise (N). Then, the snoring determination module 27 checks the presence or absence of a pre-voiced sound as shown in FIG. 4 (S40), and enters a reception standby (S50).

In this way, if the snoring determination module 27 is continuously operating, it is possible to distinguish between the noise (N) and the sound derived from the sound source, and check whether the target sound (T) is included in the snoring sound as well as the synthesized sound (S). If it is confirmed that the target sound (T) is included, the user's snoring and subsequent sleep apnea can be prevented.If not in operation, a series of snoring and sleep apnea prevention routines following the above can be used. It will end.
