Abstract: Our society has already entered aging society. By 2026, the elderly population is expected to enter the super-aged society of more than 20%. Hearing impairment is a very dangerous disease that lowers the quality of life in aging society. Auditory acuity should be well managed in normal circumstances, as it is rarely recovered once it is damaged. However, it is very difficult to confirm the degree of auditory acuity in daily life. Therefore, the self measurement method of auditory acuity is very necessary. In this study, we propose an auditory acuity measurement method using the hearing threshold of the extended high frequency which is very different from auditory acuity. It is a way to tell three levels of sound in the band above 12,000 Hz and count the number of sounds heard. The experiment was conducted on 10 people who normally communicate with the proposed method. As a result of the experiment, nine people heard sounds close to the predicted expectations for each age group. However, in one case the number was <10. In addition, nine people who listened to the predicted expectation showed the difference in the number of sounds heard according to auditory acuity. As a result of this experiment, we confirmed that the proposed method using the extended high frequency is effective as a self measurement method to measure auditory acuity by itself.
