摘要 提出一种基于DSP的全数字助听器宽动态压缩算法。该方法在频域分析的基础上,对于不同的频率分量,根据其能量的差异,分别给予不同的压缩算法。借助DSP助听器实验平台实现算法,并通过真耳佩戴后的听力学测试,验证了该信号处理方法的有效性。 This paper puts forward the algorithms of wide dynamic range compression for digital hearing aid （DHA） based on DSP. In this algorithms the spectrum of input signal is analyzed firstly, and then different compression algorithms are choose on different frequency according to energy. The algnrithms is realized on algorithms developing platform for DHA. Experimental result of audiometry shows the algorithms are available.
