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.

本研究提出一种助听器降噪系统。在日本，助听器的扩散率约为25%，助听器的传播需要降低语音中叠加的背景噪声的降噪。针对背景噪声的变化，提出了一种能够跟踪背景噪声变化的降噪系统。仿真结果表明，该系统能够提高系统的降噪能力。此外，还制作了具有降噪功能的助听器样机。
