A Gain Compensation Algorithm for Hearing Aid using the Voice Activity Detection

초록

Abstract - In this paper, we propose a novel approach to improve the speech quality of the hearing aid in noisy environment. The conventional gain control algorithm suppresses the noise of input signal, and then the part of wide dynamic range compression (WDRC) amplifies the undesired signal. The proposed algorithm controls the gain of hearing aids according to speech present probability by using the output of a voice activity detection (VAD). The performance of the proposed scheme will be evaluated under various noise conditions by using objective measurement
