Description

Anti-Snoring Device Capable Of Stopping Selectively User`s Snoring Out Of A Plurality Of Snoring Sounds by selecting a user from among 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 is snoring during sleep or is in an apnea state 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 allow the user to stop snoring or apnea during sleep by applying a stimulus to awaken the user's sleep.

An anti-snoring device that can stop snoring by selecting a user from most of the plurality of snoring sounds so far is, for example, as shown in Registered Utility Model No. 20-0475814 (automated anti-snoring bed system), the human body It is intended to include at least one or more sensing parts mounted in contact with a part of the .

However, the snoring prevention device as described above determines whether a person is snoring by using a sensing component for each snoring measurement target, that is, each user, or receives a snoring sound while sleeping alone in an independent space to determine whether the person is snoring. .

Therefore, in order to determine snoring, the conventional anti-snoring device necessarily requires an individual device for snoring measurement, so the unit price of the entire device rises, and in order to use it, it has to be worn on a specific part of the body, causing inconvenience in use. There was a problem that followed.

In addition, when snoring is determined by directly receiving the snoring sound through the receiving device, if another person sleeps in the defined space where the user sleeps at the same time, the user's snoring sound cannot be distinguished. In addition to causing discomfort, there was a problem in that the accuracy of snoring judgment was greatly reduced 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 problems of the conventional anti-snoring device as described above, and without using any type of part or device directly worn on the user's body for determining whether snoring is present, snoring In the defined space where this measurement is made, it is possible to determine whether the user is snoring or sleep apnea following snoring, even if a number of people other than the user go to bed at the same time as a control. The purpose of this study is to improve the accuracy of judgment regarding sleep apnea or not.

In order to achieve this object, the present invention compares one or more snoring sounds sampled from a sound source consisting of a user alone or a user and one or more control groups, that is, a sound received in real time during operation, that is, a measured sound, and the measured sound. a mobile terminal for determining whether a target sound generated by the user is included; and an arousal operation means for waking up the user's sleep when the measured sound is the target sound as a result of determination by the portable terminal; Provided is a snoring prevention device capable of stopping snoring by selecting a user from among a plurality of snoring sounds, each including a snoring determination module configured to be sampled independently.

In addition, the snoring determination module comprises: a synthesizer for selectively synthesizing the snoring sound sampled from the sound source from among all the snoring sounds so as to compare them with the measured sound; and a determination unit that compares the snoring and the synthesized sound with the measured sound, and determines whether the target sound is included in the measured sound through the snoring and the synthesized sound coincident with the measured sound. It is desirable to do

In addition, when the number of the sound sources is n, the synthesis stage synthesizes samples from different sound sources so that the second to nth order of the snoring sound is _n C ₂ to _n C _n times to generate the synthesized sound. it is preferable

In addition, when the number of sound sources is n, when the measured sound increases by more than the reference pressure, the determining unit determines whether the snoring and the synthesized sound are the snoring and the synthesized sound, excluding the established sound from the measured sound, when the number of sound sources is n. _n C _{1 to n} times at most, and when the measured sound is neither the snoring sound nor the synthesized sound, it is preferable to determine it as noise.

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

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

In addition, when the number of the sound sources is n, and the number of the sound sources is n, and when the measured sound decreases by more than the reference pressure, the addition or subtraction sound assuming that the target sound is excluded from the ready-made sound is the target sound from the snoring sound and the synthesized sound Whether or not it coincides with the subtracted sound by subtracting from the snoring and the synthesized sound is compared up to n-1 C 1 to n-1 times at most _n-1 C _{1 to n-1} times, but the subtracted sound is the target sound from the snoring and the synthesized sound When the order is reduced to n-1, and when n is 1, that is, when the order is 0, the ready-made sound and the target sound are the same, so no comparison is made. It is preferable to determine that the pure attenuation sound obtained by subtracting the measured sound from the sound is noise.

In addition, when the determination stage matches the addition and subtraction sound as a result of comparison with the subtraction sound, since the target sound assumed to be excluded when obtaining the addition or subtraction sound is the true target sound, the pure tone is determined that the target sound is Therefore, it is checked whether the user is present in the current sleeping position by the user sensing means, and as a result, when it is confirmed that the user is in the current sleeping position, it is determined that the user is in a sleep apnea state following snoring. desirable.

In addition, it is preferable that the snoring determination module samples the corresponding snoring sound from the false snoring produced by one of the user and the control group in an awake state.

In addition, the arousal operation means is made of a speaker mounted on one side of the mattress of the bed, the speaker when the user sleeping on the mattress snoring, by transmitting a vibration to the user through the mattress to stimulate the user's sleep It is desirable to awaken

In addition, the arousal operation means is made of an actuator mounted on one side of the foldable bed, and when the user sleeping on the foldable bed snores, the actuator rotates one side of the bed relative to the other side to stimulate the user by stimulating the user. It is desirable to awaken the sleep of

In addition, as another embodiment of the present invention, one or more bruising sounds sampled from a sound source consisting of a user and one or more control groups are compared with a sound received in real time during operation, that is, a measured sound, and the measured sound is received from the user. a mobile terminal that determines whether the generated target sound is included; and an arousal operation means for waking up the user's sleep when the actual measurement sound is the target sound as a result of determination by the portable terminal; Provided is a snoring prevention device capable of stopping snoring by selecting a user from among a plurality of snoring sounds, each of which includes a bruxism determining module configured to independently sample bruising sounds.

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 device of the present invention largely includes a mobile terminal 3 and a wake-up operation means 5.

Here, the portable terminal 3 is a small device that can be carried by a user, such as a normal mobile phone, and includes not only a basic configuration related to data storage and communication, such as a control unit, a memory, a wireless communication unit, etc., but also a signal transmission/reception and input/output function, in addition to a call function. It means a device that includes ancillary components such as a microphone, recorder, and speaker for

Therefore, in the present embodiment, the portable terminal 3 collects and stores snoring, and compares the collected snoring with the actually measured sound during sleep to find the user's snoring, 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 the size, pitch, or tone of the sound, but it is not affected by the phase difference of the sound wave and is compared through the tone determined according to the waveform. it is preferable However, since tones are affected by overtones, it is desirable to match the conditions for occurrence of overtones when comparing snoring samples sampled through tones and actual sound. Accordingly, it is important to place the portable terminal 3 and the user in the same position as will be described later when sampling and measuring snoring.

To this end, as shown in FIG. 2 , the portable terminal 3 includes a communication unit 11 , a microphone 13 , a display 15 , a memory 17 , an awakening operation unit 19 , and a user sensing unit 20 . , 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 wire or wireless in the present invention, respectively. 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 recently, according to the development of communication technology, a large amount of digital data is transmitted through a wide spectrum frequency with low power in a short distance section. Ultra-wideband wireless technology for transmitting and receiving is employed. 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 again sent to the control unit 21 through the awakening operation unit 19 . 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-in or connected to the portable terminal 3, like a general microphone used in a mobile phone, etc., and is used for making a phone call or voice recording. In particular, in the present invention, the microphone 13 records and samples snoring sounds from various sound sources such as the control group as well as the user through the audio unit 23 according to the command of the control unit 21, or when the snoring prevention device 1 is operated. Afterwards, it serves to acquire in real time various sounds, that is, measured sounds, including the snoring sound of a control group consisting of one or more people. In this case, the control group refers to other people sleeping together in the defined space when the user sleeps in the defined space. For example, if the sleeping space is the couple's bedroom, the control group will be the 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. Thus, in the present invention, it serves as an interface for connecting the user and the control unit 21 through the display unit (25). That is, the display 15 implements various screens for executing and terminating 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 snoring samples sampled from a user and a control group, as well as a snoring prevention device (1) It serves to store various sounds input through the microphone 13 while being used.

The awakening operation unit 19 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 configuration added in another embodiment of the present invention, and serves to transmit a user presence signal detected by the user detection means 7 to the control unit 21 .

The control unit 21 is a part that controls all elements of the portable terminal 3 from the above-mentioned communication unit 11 to the awakening operation unit 19 or the user sensing unit 20, and refers to the integrated CPU and GPU. , may include a communication unit 11 in some cases. Therefore, 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 actually measured sound I inputted in real time through the microphone 13 during use, and , it is determined whether the measured sound (I) includes the target sound (T) generated by the user, and as a result of the determination, when the measured sound (I) includes the target sound (T), it is awakened through the arousal operation unit 19 By operating the operation means (5) to awaken the sleeping user to stop snoring. Or, when the measured sound (D) becomes smaller than the established sound (F) existing in the defined space before waiting for the reception of the measured sound, it is assumed that the target sound (T) is excluded from the established sound (F) ( By comparing U) with the snoring and the subtraction sound (-S) obtained by subtracting the target sound (T) from the synthesized sound (S), the user's sleep apnea is checked according to whether or not the user's sleep apnea is confirmed accordingly. Awakens the sleeping user to stop sleep apnea. 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 follows the breathing cycle of the found target sound T and monitors the target sound T. 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 determines the user-generated snoring or sleep apnea following snoring. In order to do this, each snoring sound is independently sampled from the sound source comprised of the user as well as the control group. To this end, the snoring determination module 27 again includes a synthesis stage 31 and a determination stage 33, and first, the synthesis stage 31 provides snoring samples sampled from the user and the control group, that is, from the sound source. As a part of synthesizing so that it can be compared with the actual sound, a synthesized sound is made by selectively synthesizing all snoring sounds sampled from the sound source before the monitoring by the snoring prevention device 1 starts. In this case, it is desirable to sample all snoring while maintaining the same distance or condition 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. sample At this time, since the user is not sleeping, in this way, in order to sample the user's snoring sound, the portable terminal 3 is placed as much as possible while sleeping and the recording is performed. You can sample more conveniently by making and recording. 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 is generated not only in the inhalation but also in the exhalation, the snoring sound of the inhalation and the exhalation is made during sampling and both are sampled as the snoring sound of one user.

In addition, when a couple of users sleep together in the above defined space, since there are two sound sources, the sounds that can be made in the defined space are T for the user's snoring and A for the spouse, that is, the control group's snoring, T and Two snoring sounds of A and one synthesized sound of TA make a total of three. At this time, the sampling of the spouse, that is, the control group may also be performed by recording the false snoring sound of the control group through the portable terminal 3 placed in the position to be put during sleep, as in the case of the user alone, and each control group sleeping alone In this state, the actual snoring may be recorded by recording the sound. Furthermore, if there is a received sound, except for the snoring sound sampled from the user and the control group, and a synthesized sound thereof, the entire sound is regarded as another control group and the target sound is determined.

In addition, the determination stage 33 compares the snoring sound and the synthesized sound generated from the sound source as above with the measured sounds I and D measured by the portable terminal 3 to determine whether they match. As a result, when the 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 arousal operation means 5 is operated. However, since it is difficult to accurately match the snoring sound and its synthesis, the synthesized sound (S) and the measured sound (I, D), it is difficult to accurately match the snoring sound and the synthesized sound with an error range of 10 to 20% for the measured sound. It is preferable to judge

On the other hand, the arousal operation means 5 is a means for directly waking a sleeping user to stop snoring, and a variety of 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). When the speaker 51 is employed 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 the applicant's Patent Registration No. 10-0684071. By causing vibration in the air mattress (AM) according to the instruction of the arousal operation unit 19, it is possible to stimulate and awaken the user who is snoring during sleep to stop snoring. However, it is preferable that the speaker 51 can be set to a predetermined intensity by varying the intensity of vibration, and a speaker that only vibrates and does not generate a sound is used so as not to interfere with the detection of snoring.

In addition, the actuator 53 is mounted on the joint portion J of the folding frame F that supports the folding mattress BM of the folding bed B, as shown in FIG. Accordingly, one end of the foldable mattress (BM), in particular, by rotating and lifting the head, may stimulate the user's sleep to stop snoring.

In addition, the user sensing 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 a sleep apnea state following snoring during sleep. used in other embodiments of the invention. Therefore, the user sensing means 7 is, for example, in the case of the vibration system disclosed in this patent No. 10-0684071 shown in FIG. 1, although not disclosed in the publication, the air compressor (C) and the air mattress (AM) By using the pressure sensor installed on the pipe line of the hose (H) connecting the It can be confirmed by changing the load. That is, when the user lies on the mattress AM and the load increases, the internal pressure of the mattress AM rises, so the controller 21 detects this through the pressure sensor to confirm that the user is on the mattress AM. In another case, when the user sensing means 7 is applied to the folding mattress BM of the folding bed B shown in FIG. In this case, a thin plate-type load cell may be employed as the user sensing means 7 , and therefore, of course, the presence or absence of a user on the foldable mattress BM can be confirmed through the pressure change sensed by the user sensing means 7 . .

In addition, the system 1 of the present invention replaces the sound of snoring with the sound of bruising, and awakens the user's sleep in the same manner as above, thereby allowing the user to stop bruising. To this end, the system 1 samples each bruising sound from a sound source composed of a user and one or more control groups using a portable terminal. Since it is difficult to make, while sleeping for sampling, each individual's grinding sound is recorded independently during sleep. Above, since the rest of the matters related to the prevention of bruises are the same as those of the prevention of snoring, a detailed description thereof 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 snoring sounds from all sound sources including the user (S20). For this purpose, as described above, the mobile terminal 3 is placed at the position where the user sleeps, that is, the storage position, and the user and the control group use the microphone 13 to generate the snoring sound created by false inhalation and exhalation respectively. Each snoring sound is recorded individually, that is, singly, or an actual snoring sound is recorded individually and sampled as each snoring sound. However, when recording false snoring, it is desirable for the user and the control group to record at a sleeping position within the defined space where sampling is performed. In this way, when sampling of the snoring sound is completed, the snoring determination module 27 makes a synthesized sound by synthesizing and synthesizing the snoring sound sampled by the synthesis stage 31 selectively without omission. At this time, the number of sound sources is 1 to If it is n, the sampled snoring sounds S are S ₁ to S _n . That is, if there are three control groups, including the target sound (T), which is the user's snoring sound, there are 4 snoring sounds (T, A, B, and C) in total, A synthesized sound is generated by synthesizing samples from different sound sources as much as possible over _n C ₂ to _n C _n times. That is, for example, by synthesizing 4 snoring sounds T, A, B, and C over ₄ C ₂ =6 times so that the order is 2nd, a total of 6 synthesized sounds are generated: TA, TB, TC, AB, AC, BC. do. The synthesized sound synthesized ₄ C ₃ =4 times to make the 3rd order is TAB, TAC, TBC, and ABC, and a total of 4 synthesized sounds are generated. Finally, only one TABC is generated for the synthesized sound that is synthesized ₄ C4 = 1 time to become the 4th order. However, when sampling a snoring sound from a sound source, if the sampling position is matched with the sleeping position of each sound source during sleep, each snoring sound coincides with the snoring sound generated during sleep and even the overtone.

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

Then, the snoring determination module 27 checks whether an effective sound of a certain pressure or more already exists in the defined space before entering the reception standby mode, and if necessary, frequency-converts it (S40).

In this way, when preparation for operation is completed, the user puts the portable terminal 3 in the storage position and goes to sleep, and goes to sleep at his or her sleeping position set to be the control group as well. The portable terminal 3 waits for any sound to be received (S50).

Eventually, when a meaningful sound having a sound pressure greater than or equal to the reference pressure is captured through the microphone 13, preferably, the increased sound signal, that is, the measured sound (I) can be frequency-converted through FFT, and the measured sound (I) Subtract the sound (F) above to obtain the pure 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 stage 33 (S70). For this, each snoring sound having the first order, e.g., whether the four snoring sounds T, A, B, C sampled from the four sound sources including the user above, match the pure tone (Ri) up to _n C Compare _once (S71). At this time, since n is 4, it is checked whether the pure sound (Ri) and the snoring sound match up to ₄ C ₁ =4 times. That is, it is checked whether Ri=T?, Ri=A?, Ri=B?, Ri=C?.

As a result of checking, if Ri = T and the pure sound (Ri) matches the target sound (T) among snoring sounds, since the pure sound (Ri) is derived from the user, the arousal operation means ( 5) is operated (S80) to stimulate the sleeping user, thereby stopping the user's snoring.

After that, 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, the series of snoring prevention routines are ended.

On the other hand, as a result of the comparison in the above step S71, if it is confirmed that the pure enhanced sound Ri does not have the first order, as a next step, the pure enhanced sound Ri is compared with the synthesized sound having the second order (S72). ). In other words, by selectively synthesizing the pure tone (Ri) and each synthesized sound having the second order, for example, the four snoring sounds T, A, B, C sampled from the four sound sources including the user as above, with other snoring sounds. The synthesized sound is compared up to _n C ₂ times (S72). That is, for example, it is compared whether the six synthesized sounds of TA, TB, TC, AB, AC, and BC are consistent with each other, up to ₄ C ₂ =6 times.

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

When this process is generalized, the snoring discrimination module 27 compares the pure tone 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 pure sound (Ri) is compared with the synthesized sound TABC over _n C _n = 1 times. ) coincides with the nth synthesized sound, the arousal operation means 5 can be operated immediately without checking whether the target sound T is included in the pure augmentation Ri (S80), and even in this case, the user to stop snoring.

However, if the pure sound (Ri) and the nth synthesized sound do not match, the pure sound (Ri) is not a sound generated from a sound source, so it is defined as noise (N) (S90), and the snoring prevention device 1 is again It enters the standby mode for sound reception (S50). However, before that, it is checked in advance whether there is a ready-made sound (F), and if there is, the frequency is converted (S40).

After that, if a significant sound having a sound pressure greater than or equal to the reference pressure is added to the noise (N) that has been continuously received as the ready-made sound (F) and a change occurs, similarly, the pure sound (Ri) is obtained (S60), and the above process (S70) is followed. If repeated again, it is possible to prevent the user from snoring continuously while the snoring prevention device 1 is in operation, and if it is not in operation, the above series of anti-snoring routines ends.

In addition, although a detailed description is omitted, the user's teeth grinding can be stopped by waking the user's sleep in the same manner as above through the teeth grinding sound.

Meanwhile, 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), snoring is sampled and synthesized sound is formed. (S20), frequency-converts the sampled sound as needed (S30), checks whether there is a ready-made sound (F) (S40), waits for the reception of the sound (S50), and when the measured sound (I) is received After subtracting the established sound (F) from the measured sound (I) to obtain the pure sound (Ri) (S60), by comparing the pure sound (Ri) with the snoring and synthesized sounds (S70), target the pure sound (Ri) When the sound (T) is included, a series of anti-snoring 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 the sound (S50), if the received sound, that is, the measured sound is the same as the prepared sound (F), as shown in FIG. If the sound received while waiting (S50), that is, the measured sound (D) is significantly reduced by more than the reference pressure than the ready-made sound (F), if necessary, the reduced measured sound (D) is frequency-converted, 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 determining unit 33 first obtains an addition (U) subtracted from the voiced sound (F) confirmed in the step (S40) by assuming that the target sound (T) has been erased (S100). Next, a subtraction (-S) obtained by subtracting the target sound (T) from the synthesized sound (S) is obtained before the addition and subtraction (U) are compared with the synthesized sound (S) (S110). At this time, for example, if the sound source is T, A, B, C, D, n is 5, and for the second-order synthesized sound, 10 of TA, TB, TC, TD, AB, AC, AD, BC, BD, and CD are generated. do. There are four synthetic sounds including the double target sound (T), TA, TB, TC, and TD. ) is subtracted, so the order of the subtracted sound (-S) is reduced by 1 compared to the synthesized sound (S). For example, the synthesized sounds TA, TB, TC, and TD become A, B, C, and D. On the other hand, if the target tone (T) is subtracted from AB, AC, AD, BC, BD, and CD, it becomes a different note from A, B, C, and D. , it can be seen that D does not match. Therefore, when the addition (U) and subtraction (-S) are first compared, the order of the subtraction (-S) becomes the 1st order, and is expressed as U = -S ₁ ?. And, the maximum number of comparisons becomes _n-1 C ₁ = ₄ C ₁ =4 times.

As such, when the unknown sound, that is, the pure attenuation Rd, is canceled from the established sound F and the measured sound D is reduced, in order to determine whether the erased sound is the target sound T (S120) ), addition and subtraction (U), assuming that the target sound (T) is subtracted from the original sound (F), and the target sound among subtraction sounds (-S) whose order is decreased by 1 by subtracting the target sound (T) from the synthesized sound (S) By comparing only those containing (T) up to _n-1 C _once , it can be confirmed whether the target sound (T) has been deleted from secondary sounds among the synthesized sounds (S). That is, if, for example, the subtraction (-S) A obtained by removing the target sound (T) from TA, which is an additive (U) and a synthesized sound (S), is matched, the ready-made sound (F) is a TA, and thus the ready-made sound ( The assumption that the addition or subtraction (U) is the target sound (T) is confirmed to be true (S121). In this case, if it is detected by checking whether the user is in the sleeping position next (S130), the user has stopped snoring while in the sleeping position, so it is determined as sleep apnea, and the user performs a sleep awakening operation through the awakening operation means (5) It becomes possible to stop the apnea of (S140). However, if the user is not detected, as shown in FIG. 4 , it is checked whether there is a ready-made sound (S40), and the reception standby is entered (S50).

In the same way, the result is the same as the result of checking whether U = A, B, C, D up to 4 times by comparing _{n-1 C} at most once, that is, whether U = A, B, C, D. is not obtained, since none of the subtractive sounds (-S ₁ ) with the 1st order lowered to the 1st order match the addition/subtraction sound (U), the next step is addition or subtraction among the 1st order subtraction tones (-S ₂ ). It is checked whether there is anything that matches the note (U) (S122).

In the same way, it is checked whether the final subtraction (-S _n-1 ) matches the addition or subtraction (U) (S12n). At this time, the final subtraction sound (-S _n-1 ) is n-1 because the order is 1st order down from n. As a result, if there is a subtraction (-S _n-1 ) that matches the addition and subtraction (U) as above, you can stop the sleep apnea following snoring in the same way as above (S140), and if there is no matching result, The pure attenuation (Rd) is judged as the noise (N). Then, the snoring determination module 27 checks whether there is a ready-made sound as shown in FIG. 4 (S40), and enters the reception standby (S50).

In this way, if the snoring determination module 27 is continuously operating, it is possible to distinguish the noise (N) from the sound source-derived, and it is possible to 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, it is possible to prevent the user's snoring and sleep apnea following it. will end
