Abstract

PROBLEM TO BE SOLVED: To prevent a gain over a required gain from being provided in the case that a hearing aid is mounted to both ears and to adjust the hearing aid to have a characteristic in which a sound source is localized at a correct position with respect to both the ears by adjusting the characteristic of the hearing aid based on a loudness increase curve in the case of hearing by both the ears. SOLUTION: A measurement section 140 measures a presented sound pressure at which left and right audible loudness are equal to each other at a plurality of points on a loudness function based on a loudness increasing function in the case of hearing by a single ear. A check sound level decision means 260A sets a check sound so that left right audible loudness sets are equal to each other to measure a loudness increasing function in the case of hearing by both the ears. A hearing aid adjustment means 150A adjusts the characteristic of the hearing aids mounted to the left and right ears based on the loudness increasing function in the case of hearing by both the ears. Thus, the hearing aids are adjusted in which a proper gain or a proper amplitude compression characteristic is obtained in the case of mounting each hearing aid to both the ears and a sound source is localized at a correct position.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hearing aid adjusting device.

[0002]

2. Description of the Related Art A conventional hearing aid adjusting device is shown, for example, in U.S. Pat. No. 4,731,850.

FIG. 23 shows a block diagram of this conventional hearing aid adjustment device. 10 is a hearing aid adjustment device, 20 is a hearing aid adjusted by the hearing aid adjustment device, and 30 is a hearing aid user who uses the hearing aid 20. . Reference numeral 40 is a hearing aid measuring means in the hearing aid adjusting device, and 50 is a hearing aid adjusting means. Reference numeral 60 is a test signal source for generating test signals such as pure tone and band noise. 70 is a user reaction detecting means, 8
Reference numeral 0 is a hearing data determining means, and 90 is a gain characteristic adjusting means.

The operation of the conventional hearing aid adjusting device configured as described above will be described. First, the hearing acuity measuring means 40 is used to measure the residual hearing ability of the hearing aid user. Specifically, the frequency characteristic of the gain of the hearing aid 20 is made flat and the gain is made constant, and then the level and frequency of the output signal of the test signal source 60 are changed and input to the hearing aid 20. The output signal of the hearing aid 20 is heard by the hearing aid user 30 in the hearing aid wearing state, and the user reaction detecting means 70 detects the subjective level of the test signal sound felt by the hearing aid user. The user reaction detecting means 70 determines the volume of the sound as (1) inaudible, (2) audible, (3) just loud, (4) slightly loud, (5) uncomfortably loud.
It is divided into stages and the hearing aid user is made to respond to the reaction with a push button or the like. The hearing data determination means 80 determines, based on the frequency of the test signal source, the signal level, and the reaction of the user,
Each week of the user determines the minimum audible value (HTL), comfort value (MCL), discomfort threshold (UCL), etc. in number. The gain adjusting means 90 determines the frequency characteristic of the gain of the hearing aid based on the determined minimum audible value (HTL), comfort value (MCL), discomfort threshold (UCL), etc., and makes the hearing aid the characteristic closest to the frequency characteristic. Adjust so that

[0005]

However, in the above-described configuration, when the hearing aid 20 has one input and one output, the hearing of the left and right ears is adjusted independently. However, the minimum audible value (HTL), comfort value (MCL), discomfort threshold (UCL) when listening with both ears
Is known to be lower than the minimum audible value (HTL), comfort value (MCL), and discomfort threshold value (UCL) when listening with a single ear. The conventional hearing aid adjustment device adjusts the left and right hearing aids independently and cannot consider the effect of binaural hearing. Therefore, when wearing a hearing aid in both ears, there is a problem in that it is annoying because an unnecessary gain is given. Most hearing-impaired people have different left and right minimum hearing values (HTL), comfort values (MCL), and discomfort thresholds (UCL). ), The balance of the discomfort threshold (UCL) cannot be taken into consideration. Therefore, when the hearing aid is worn on both ears, there is a problem that the sound source cannot be localized at the correct position.

The present invention is intended to solve the above-mentioned conventional problems, and adjusts the hearing aid to a characteristic that does not give an unnecessary gain when the hearing aid is worn on both ears, and wears the hearing aid on both ears. It is an object of the present invention to provide a hearing aid adjustment device that adjusts a hearing aid to a characteristic such that a sound source can be localized at a correct position in such a case.

[0007]

In order to achieve the above object, in the first aspect of the hearing aid adjustment device of the present invention, the left and right points are set at a plurality of points on the loudness function based on the loudness increasing function at the time of mono-ear listening. The loudness of hearing is measured to be equal, the test sound is set so that the loudness of the left and right hearing are equal, and the loudness increasing function during binaural listening is measured. Based on the second and third aspects of the hearing aid adjustment device of the present invention, the characteristics of the hearing aids worn on the left and right can be adjusted based on the loudness increasing function at the time of monophonic hearing. The loudness increasing function is estimated, and the characteristics of the hearing aids worn on the left and right can be adjusted based on the estimated loudness increasing function when listening to both ears.

According to the above-mentioned first means of the present invention, the loudness of the left and right hearing of the hearing aid user is balanced, and the loudness increasing function at the time of hearing with both ears is obtained with the left and right loudness balanced. Since the characteristics of the hearing aid are adjusted based on the measured loudness increasing function during binaural listening, the gain or amplitude compression characteristics are appropriate when the hearing aid is worn in both ears, and the sound source is localized at the correct position. It can be adjusted to a state where it is possible.

According to the above-mentioned second means of the present invention, the loudness increasing function at the time of hearing by both ears is estimated from the loudness increasing function at the time of hearing by the hearing aid user's left and right hearing, and the estimated binaural is estimated. Since the characteristics of the hearing aid are adjusted based on the loudness increasing function at the time of listening, it is possible to adjust the gain or amplitude compression characteristics suitable when the hearing aid is worn by both ears.

According to the above-mentioned second means of the present invention, when the left and right hearing loudness increasing functions of the hearing aid user are different, the difference between the left and right loudness functions is taken into consideration, and the loudness increasing function at the time of monophonic listening is taken into consideration. By estimating the loudness increasing function during binaural listening and adjusting the characteristics of the hearing aid based on the estimated loudness increasing function during binaural listening, appropriate gain or amplitude compression characteristics when wearing the hearing aid in both ears It is possible to adjust the sound source so that it can be localized at the correct position.
