Abstract

In this paper, we improved the high frequency noise characteristics of the previously proposed hearing aid circuits for presbycusis, and we designed and fabricated a stereo hearing aid module. The cause of high frequency noise, which occurs in some cases in the previous circuits under high gain conditions, was analyzed through simulations. Two mute switches were added to adjust each boosting gain for right and left ears more accurately by muting the sound of the other ear when adjusting the gain of one ear in the stereo hearing aid module.

본 논문에서는 기존에 제안한 노인성 난청으로 인한 청력도 감쇄를 보상하는 회로의 고주파 잡음 특성을 개선하고, 입체 음향을 지원하는 양 이(耳)형 보청 모듈을 설계·제작하였다. 고 이득 조건에서 경우에 따라 발생하는 기존 회로의 고주파 잡음 원인을 모의실험을 통해 분석하였다. 양 이 형 모듈에는 조절 대상 반대쪽 귀에는 음을 소거하여 보다 정확하게 오른쪽과 왼쪽 귀에 맞는 증폭 이득을 조절할 수 있도록 음 소거 스위치를 추가하였다.
