摘　　要：为便于研究人体听觉系统生理结构及生理响应与响度感知之间的关系,构建了一种基于人耳生理结构的响度感知预测模型。首先,通过整合外耳滤波器、中耳等效电路模型及耳蜗传输线模型,构建了基于人耳生理结构的听觉外周传声模块,将外部的声输入转变为耳蜗内基底膜响应;其次,通过兴奋模式、特定响度、响度的计算,构建了模型的后端处理模块,将基底膜响应该物理响应转变为与神经发放相关的响度感知;再次,通过对比中耳压强增益、基底膜特征频率及品质因子,验证模型生理传声特性模拟的可靠性;最后,通过响度增长曲线、等响曲线、响度临界带宽的对比,证明模型在响度感知预测上的可信度。研究结果表明,所构建的响度感知预测模型不仅能够较好地模拟人耳生理结构的传声特性,还能够有效预测响度感知特性。To facilitate the study of the relationship between the physiological structure and response of the human auditory system and the loudness perception,a loudness perception model based on the human-ear physiological structure is constructed.Firstly,by integrating the outer-ear filter,the middle-ear circuit model and the cochlear transmission line model,an auditory peripheral sound transmission module based on the human-ear physiological structure was established,which converts the external sound into the basilar membrane response.Secondly,a back-end processing module of the loudness model,which transforms the basilar membrane response into a loudness perception related to neural firing,was constructed by the calculation of the excitation pattern,specific loudness and loudness.Thirdly,by comparing the middle ear pressure gain,basilar membrane characteristic frequency and quality factor,the reliability of the model's simulation of physiological sound transmission characteristics was verified.Finally,through the comparison of loudness growth curve,equal loudness curve and loudness critical bandwidth,the reliability of the model in loudness perception prediction was proved.The research results show that the constructed loudness perception model can not only simulate the sound transmission characteristics of the human ear physiological structure,but also effectively predict the loudness perception characteristics.
