Abstract

PURPOSE:To listen to surrounding sound, especially distant voice and acoustic sound, by making the level of own voice lower than that of surrounding sounds. then rising the sound volume of the hearing aid. CONSTITUTION:When a person who fitted with a hearing aid 1 and a bone conduction type microphone 6 speaks, the bone conduction voice signal (oscillation) is picked up by an oscillation pick-up 6A of a microphone 6 and it is electrically changed. Then, gathering sound electric signal sent from the microphone 2 is lowered (for example, approx. 10dB or equivalent), the operation of automatic volume controller 4 of the hearing aid 1, and output of a receiver 5 is dropped down. Therefore, voice of a person who is fitted with the hearing aid 1 output in the decreased voice level. As a result, distant voice sound and surrounding acoustic sound is easily heard by setting the volume of the hearing aid 1 large.
