Description

Apparatus for testing hearing ability using monosyllable and method of the same

The present invention relates to a hearing test apparatus using monosyllabic words and a method for performing the same.

Statistically, approximately 0.1 to 0.2% of the population have profound hearing loss, in which no sound is heard, 1 to 2% have moderate and severe hearing loss, and 10 to 15% have mild hearing loss ( mild hearing loss). Here, mild hearing loss refers to a person who has a disability in hearing about 20 to 40 dB, and does not have much difficulty in conversing with people nearby. However, in the case of such mild hearing loss, most are unaware of the severity, so there are not many cases of visiting a hospital for mild hearing loss. In more severe cases, it can progress to severe or profound hearing loss.

In modern society, many people live in contact with a number of sound reproduction devices, and representative examples include radios, CD players, MP3 players, audio players, PCs, and language players.

In particular, as personal sound devices such as MP3 players and smartphones become common, the age of hearing loss is gradually decreasing, and interest in improving the working environment of workers exposed to continuous noise in industrial settings is growing. Hearing loss can progress slowly and you can lose your hearing without your knowledge.

In order to respond to hearing loss, it is important to be aware of the individual's hearing condition on a daily basis to prevent and treat hearing loss at an early stage. However, for early detection, periodic hearing tests are required, so there is no time to visit the hospital, or the distance from the hospital is far from the hospital to prevent timely examinations. In addition, since the hearing test examines the testee's response to sound for each frequency, reliable threshold values can be determined only when performed in a quiet environment such as a soundproof booth. However, there is a problem that the soundproof booth requires an examination space of a certain size and an expensive installation cost, and it can be used only by visiting a hospital or a designated place where a hearing test is possible. Conventional efforts to perform a hearing test in a noisy environment are as follows. Headphones such as circumaural earphones can completely cover the ears to enhance the soundproofing effect, but deliver a sense of pressure to the subject's ears, and the subject may complain of stuffiness. In the case of an insert earphone capable of inserting the device close to the ear, the effect of sound transmission is great, but there is a limitation in blocking in a low frequency band. Both of these earphones have a passive offset effect, but there is a limit as a means of blocking ambient noise because the test results vary depending on the wearing state.

In addition, by outputting a consistent test sound without considering the hearing condition of the examinee, and examining the hearing by receiving an input whether the examinee can hear the test sound, a meaningless test sound is output to increase the test time and accuracy of the test There is a problem of falling.

Among the components of the hearing test apparatus 100 using monosyllabic words according to the present invention, only the components related to the function of 　test hearing, displaying the test result or applying the test result to reproduce the sound source will be described. Accordingly, it can be understood by those of ordinary skill in the art related to the hearing test apparatus 100 using monosyllabic words that other general-purpose components may be further included in addition to the components shown in FIG. 2 .

The hearing test apparatus 100 using monosyllabic words according to an embodiment of the present invention is a device that can be carried by a person who tests hearing 　, and reproduces a sound source or outputs a signal for reproducing a sound source. In this case, being portable means that there is no inconvenience in holding the hearing test apparatus 100 using monosyllabic words in hand or carrying it on the body. Also, the device for reproducing a sound source refers to a device that generates a sound audible to the examinee from data stored in the form of a digital or analog signal, or outputs a signal that generates a sound that the examinee can hear. For example, the hearing test apparatus 100 using monosyllabic words, a mobile phone, a personal digital assistant, an MP3 player (MPEG Audio layer-3 Player), a CD player (Compact Disc player), a portable There is a media player (Portable Media Player), etc., and the hearing test apparatus 100 using monosyllabic words is not limited thereto, and a signal that generates a sound that the examinee can hear or generates a sound that the examinee can hear Includes all devices that output .

The hearing test apparatus 100 using monosyllabic words is a device in which a function of testing hearing is added to a device that reproduces a sound that the examinee can hear or outputs a signal representing a sound that the examinee can hear. Hearing ability refers to the ability to hear sounds with the ear, and the hearing test is a test that measures the degree of hearing. That is, the hearing test apparatus 100 using monosyllabic words means a device that reproduces a sound source to which a function capable of measuring the degree of the ability to hear sound with the ear is added, or outputs a signal for reproducing the sound source do.

In this case, a signal for reproducing a sound source is a signal for generating a sound. A signal generating sound is composed of a waveform having amplitude and frequency phase. Such a signal is amplified through an amplifier to generate a sound, or a sound is generated by the output unit 120 of the hearing test apparatus 100 using monosyllabic words. In this case, the output unit 120 may be implemented as a headset 120a as shown in FIG. 1 , or may be implemented as a plurality of speakers 120a ′ as shown in FIG. 3 . The hearing test apparatus 100 using monosyllabic words may test the auditory ability of the examinee with reference to the degree of hearing the sound generated in this way.

The output unit 120 according to an embodiment may output a pure tone hearing test sound composed of pure tones as a sound for testing hearing.

The test sound generated by reproducing the signal output from the hearing test apparatus 100 using monosyllabic words stimulates the auditory organ of the examinee to allow the examinee to listen to the test sound. The output unit 120 may directly output a test sound from the hearing test apparatus 100 using a monosyllable word by using an audio signal generating a sound.

To this end, the processor 110 may set pure tone frequency information and pure tone size information of the pure tone hearing test sound. Here, the pure tone frequency information may be information indicating a pure tone frequency of a pure tone audiometry sound, and the pure tone size information may be information indicating a pure tone level of a pure tone audiometry sound.

The output unit 120 may output a pure tone hearing test sound based on pure tone frequency information and pure tone size information set by the processor 110 .

Specifically, the processor 110 sequentially sets the pure tone frequency information to any one reference pure tone frequency among a plurality of preset reference pure tone frequencies, and when the pure tone frequency information is set, the pure tone level until the point in time when audible information indicating audibility is input. The information may be set by increasing the size of a unit of pure tone from the minimum standard pure tone level.

For example, the plurality of reference pure tone frequencies may be 500 Hz, 1000 Hz, 2000 Hz, 3000 Hz, and 4000 Hz, the minimum reference pure tone level may be 0 dB, and the unit pure tone level may be 1 dB.

Accordingly, the output unit 120 may output a pure tone hearing test sound in which the pure tone frequency information is 500 Hz, 1000 Hz, 2000 Hz, 3000 Hz, and 4000 Hz, respectively, and the pure tone size information increases by 1 dB from 0 dB.

In this case, the input unit 140 may receive information on whether or not a pure tone hearing test sound is audible from the examinee. Here, the audible information may be information indicating whether the examinee can hear the output pure tone hearing test sound.

To this end, the input unit 140 may be implemented as a microphone 140a capable of inputting audible information as a voice signal, as shown in FIG. 1 , and as shown in FIG. 3 , a button for audible information It may be implemented as a keyboard 140b capable of inputting a signal, or may be implemented as a touch panel S1 capable of inputting audible information as a touch signal.

The processor 110 determines the audible pure tone level for each of a plurality of reference pure tone frequencies based on the pure tone level information of the pure tone hearing test sound output at the time when audible information indicating audibility is input, and calculates the pure tone level deviation between the audible pure tone levels. and, based on whether the pure tone size deviation is included in a preset deviation range, an average of some audible pure tone levels among a plurality of audible pure tone levels for each reference pure tone frequency may be calculated as the hearing threshold average information.

Specifically, the processor 110 determines the audible pure tone size for each reference pure tone frequency based on the reference pure tone frequency indicated by the pure tone frequency information of the pure tone hearing test sound output at the point in time when audible information indicating audibility is input, and the pure tone size indicated by the pure tone size information. can be checked with

That is, the processor 110 may check the audible pure tone for each of the plurality of reference pure tone frequencies of 500 Hz, 1000 Hz, 2000 Hz, 3000 Hz, and 4000 Hz.

Thereafter, the processor 110 calculates a pure tone size deviation between audible pure tone levels corresponding to adjacent reference pure tone frequencies, and when all pure tone level deviations are included in a preset deviation range, it is determined that the subject's hearing type is flat, and the reference pure tone An average of audible pure tones corresponding to frequencies of 500 Hz, 1000 Hz, and 2000 Hz may be calculated as hearing threshold average information.

Conversely, the processor 110 calculates a pure tone size deviation between audible pure tone levels corresponding to adjacent reference pure tone frequencies, and if one or more pure tone level deviations are out of a preset deviation range, it is determined that the hearing type of the subject is sloped, and the reference An average of audible pure tones corresponding to each of the pure tone frequencies of 1000 Hz, 2000 Hz, 3000 Hz, and 4000 Hz may be calculated as hearing threshold average information.

Thereafter, the processor 110 may select any one preliminary speech hearing test sound set from among the plurality of preliminary speech hearing test sound sets as the speech hearing test sound set to be applied to the examinee based on the hearing threshold average information.

Here, the plurality of preliminary speech hearing test sound sets may refer to a bundle of a plurality of speech hearing test sounds differently selected according to the average hearing threshold. As for the plurality of preliminary speech audiometry sound sets, an average range of the hearing threshold of the examinee may be set.

Here, the preliminary speech hearing test sound set may be composed of test sounds selected by applying a two-parameter logistic model based on Item Response Theory (IRT).

For example, the plurality of preliminary speech audiogram sets may be first to fourth preliminary speech audiogram sets, and each of the first to fourth preliminary speech audiogram sets is in the first to fourth hearing threshold range. can be matched. For example, the first hearing threshold range may be a normal hearing threshold range of 20 dB or less, the second hearing threshold range may be a mild hearing threshold range of 21 dB to 40 dB, and the third hearing threshold range may be a moderate hearing threshold range of 41 dB to 70 dB. The hearing threshold range may be a hearing threshold range, and the fourth hearing threshold range may be a high hearing threshold range greater than 71 dB.

Accordingly, the processor 110 may select a preliminary speech hearing test sound set in the hearing threshold range including the hearing threshold average information from among the hearing threshold ranges corresponding to each of the plurality of preliminary speech audio test sound sets as the speech audio test sound set. have.

Here, the selected speech hearing test sound set may mean a test sound bundle to be used for a hearing test of the examinee.

Meanwhile, as described above, the plurality of preliminary speech hearing test sounds may be a bundle of a plurality of speech hearing test sounds, and the speech hearing test sounds may be monosyllables. A monosyllable word may consist of only one syllable including at least one phoneme. A syllable is a term in phonetics and may be a minimum unit of pronunciation. A syllable may consist of a leading-neutral-final (e.g., a force composed of "h-l-ㅁ"), or a leading-neutral (e.g., a key composed of "h-l"), etc. .

In this case, the processor 110 of the hearing test apparatus 100 using monosyllabic words may include some of all monosyllabic words of Hangul in a plurality of preliminary speech hearing test sound sets through an item response theory algorithm.

To this end, the processor 110 may process the item response theory algorithm using a two-parameter logistic model. Here, the 2-parameter logistic model may be an equation defined as follows.

는 학습자의 능력 수준, a는 문항 변별도 모수, b : 문항 난이도 모수이다.here,

is the learner's ability level, a is the item discrimination parameter, and b is the item difficulty parameter.

The test sound output from the output unit 120 may be generated by the processor 110 based on data read from the storage unit 160 . At least one phoneme group classified based on the frequency represented by the phoneme is stored in the storage unit 160 . Also, in the storage unit 160 according to the present embodiment, groups of syllables classified based on the frequency indicated by the phoneme constituting the syllable may be stored.

In this case, the group of phonemes or the group of syllables includes a phoneme or syllables included in each frequency band with respect to a plurality of frequency bands within the audible frequency range. The audible frequency range is a frequency range of sound waves that the human ear can feel as sound, and refers to a frequency band of about 15 Hz or more and 20 KHz or less. That is, the audible frequency range may be classified into a plurality of frequency bands, and syllables composed of phonemes included in the classified frequency band may be grouped.

In addition, the list of vowels 202 indicates the frequency range constituting the vowels. Referring to the list 202 of vowels, one vowel is composed of three formant frequencies. In this case, the formant frequency refers to peak frequencies indicating relatively high energy in a frequency spectrum that is obtained by integrally transforming the volume (dB) of the sound relative to the time (time) representing the vowel on the frequency axis. Referring to the list 202 of vowels, three formant frequencies constituting one vowel may be represented as a first formant, a second formant, and a third formant, respectively, in order from a low frequency band. As shown in the list 202 of vowels, since most vowels are similar in frequency bands of the first and third formants, vowels can be classified into three groups based on the second formant band. have. Group 2-1 (2021) according to these classification criteria means vowels in which the second formant belongs to a frequency range of about 600 Hz or more and less than 800 Hz, and in group 2-2 (2022), the second formant has a frequency range of about 1000 Hz or more and 1300 Hz or more. It means vowels belonging to a frequency range less than or equal to, and group 2-3 2023 means vowels in which the second formant belongs to a frequency range of about 2000 Hz to less than 3000 Hz.

The vowels belonging to group 2-1 (2021) include /u/ and /o/, and the vowels belonging to group 2-2 (2022) include /ah/ and /uh/, and group 2-3 (2023). ), there are /i/, /yes/, and so on.

The input unit 140 receives the response of the examinee to the audibility of the sound reproduced by the signal output by the output unit 120 . The input unit 140 provided in the hearing test apparatus 100 using monosyllable words receives an input signal from the examinee, and displays output information to the examinee.

For example, the sound indicated by the syllable "power" is reproduced through the hearing test apparatus 100 using a monosyllable word, and the examinee receives a response to whether or not the sound indicated by the syllable is heard as "power" through the input unit ( 140) to input. In this case, the degree of audibility means the degree to which the examinee can hear the sound well. Accordingly, the degree of audibility according to the present embodiment may mean whether or not the examinee listens to the sound as a syllable as a result of listening to the sound representing the 　 syllable generated by the hearing test apparatus 100 using one syllable.

As another example, a sound represented by a phoneme “b” is reproduced through the hearing test apparatus 100 using a monosyllable word, and the examinee receives a response to whether or not the sound represented by the phoneme is heard as “b” through the input unit Input through (140). Accordingly, the degree of audibility according to the present embodiment may mean whether or not the examinee listens to the sound as the phoneme as a result of listening to the sound representing the phoneme generated by the hearing test apparatus 100 using the monosyllable word.

The input unit 140 may obtain a response to the degree of audibility from the examinee using various user interfaces. For example, in order to measure the degree of understanding of a phoneme or 　 syllable, the phoneme or 　 syllable is directly input by the examinee, and the input phoneme or 　 syllable is reproduced through the hearing test device 100 using a monosyllable word or 　 syllable. It is possible to measure the degree of hearing of the subject by judging whether it is the same as Alternatively, the subject's hearing degree is measured by selecting one phoneme or syllable corresponding to the phonemes or syllables reproduced through the hearing test apparatus 100 using one syllable among examples of a plurality of phonemes or syllables. can do. Alternatively, the examinee may select whether to listen to a phoneme or a syllable by answering “yes” or “no”.

Since the methods presented above are not an example of obtaining a response from a subject, a method of obtaining a response to the degree of hearing of the subject through the hearing test apparatus 100 using a monosyllable is not limited thereto, and various It can be seen that a method is possible.

The processor 110 controls the overall function of the hearing test apparatus 100 using monosyllable words.
