摘要
提出了一种利用Gammatone滤波器组对基底膜进行仿真的方法,代替了Mel谱中的三角滤波器,提高了与主观评测的相似度,降低了对于共振峰的频移敏感度,增强了客观测度在噪声环境中提取共振峰参数的能力。实验表明,所提算法能有效提高与MOS值的相似度。
A new approach to simulate the human basilar membrane based on Gammatone filter is put forward,so the triangle filter bank is replaced to improve the similarity of subjective evaluation and decrease the frequency shift sensitivity of the resonant peak.The capabilities of objective measurement to extract the resonant peak parameters from the noisy environments are enhanced.The experimental results show that the algorithm can effectively improve the similarity with the MOS.
