| 中文摘要 | 为了更好地理解人耳蜗的工作机制,提出了一种利用Gammatone滤波器组对基底膜进行仿真的方法。根据Gammatone滤波器组与人耳基底膜两者在冲激响应、幅频特性等方面的相似性,采用一组中心频率呈对数均匀分布的Gammatone滤波器组来模拟基底膜。采用多种信号作为输入,对该方法进行仿真测试。仿真结果表明:在纯音、混合音和语音等输入情况下,该方法能仿真人耳基底膜的动态响应过程、频率选择特性和频谱分析特性等重要特征,对于语音压缩、语音识别和人工耳蜗等听觉应用领域有参考价值。; A Gammatone filter bank method was used to simulate the human basilar membrane response to sound input to better understand the working mechanism of the cochlea.A group of Gammatone filters with logarithmic proportional spacing center frequencies were used to simulate the basilar membrane based on similarity of Gammatone filters and basiliar membrane in impulse response and amplitude-frequency characteristics.The method was implemented and simulated with various kinds of signals used as the testing stimulus. The results show that the method accurtely represents the dynamic response,frequency selectivity,and spectral characteristics of the basilar membrane when using pure tones,compound tones or voice as inputs.The simulations can facilitate developments in voice compression,speech recognition,and artificial cochlea. |
