针对数字助听器需兼顾消除语音信号中的背景噪声和听障患者可听阈问题，提出一种基于 logMMSE的宽动态压缩数字助听器算法。该算法通过 logMMSE估计消除背景噪声，同时结合听障患者听力曲线做频域宽动态压缩。仿真结果表明，基于 logMMSE的宽动态压缩数字助听器算法能使输出语音有更好的清晰度和可懂度。

Aiming at the background noise and hearing-impaired patient’s audible threshold,a wide dynamic range compres-sion (WDRC)digital hearing aid algorithm based on logMMSE speech enhancement is proposed.This algorithm estimates the background noise based on logMMSE,and wide dynamic compression combined with hearing loss listening curve is done in the frequency domain.Simulation results show that the output signal has better voice clarity and intelligibility by using the wide dynamic compression algorithm based logMMSE.
