英文摘要
In this research, a noise reduction system for a hearing aid was proposed. The diffusion rate of a hearing aid is about 25% in Japan, and the noise reduction which reduces the background noise superposed in speech is required for the spread of a hearing aid. Because the background noise is changed, the noise reduction system, which can track the change of the background noise, is proposed. From the simulation results, the proposed system can improve the noise reduction ability. In addition, the prototype of the hearing aid with the noise reduction was made.
