| 摘 要： | 对听觉滤波器组模型进行了研究。比较分析了伽马通(Gammatone)听觉滤波器组模型和基于小波分析的高斯小波听觉滤波器组模型,分别给出了预测听阈曲线并且与标准听闻曲线进行了比较,结果表明高斯小波听觉滤波器组模型更接近实际人耳滤波效果。将高斯小波听觉滤波器组模型的预测特征响度与德国朗德(Head Acoustics)公司的Artemis软件计算出的特征响度进行分析比较,结果表明,每个特征频带的响度差值都小于0.6 sone。

| Abstract: | The auditory filler bank models were studied.The Gammatone auditory filter bank model and the Gauss auditory filter bank model based on the wavelet transform were analyzed comparatively, their predicted hearing threshold curves were presented and compared with the standard one.It was found that the Gauss wavelet auditory filler bank is closer to the human ear filter result.The characteristic loudnesses predicted by the Gauss wavelet auditory filter bank model was compared with the results caleuleted by the softwave Artemis of Head Acoustics Co.,Germany,the differences were below 0.6 sone. |
