              摘要: 针对目前的响度模型无法用于预测圆窗激振下响度的问题,提出了一个适用于圆窗激振的人耳生理响度模型。该响度
              模型由听觉外周模型和数据处理后端组成。建立了能够计算自由场声激励和圆窗激振下基底膜振速的听觉外周模型以及将
              基底膜振速转变为听觉中枢所感受到的响度的数据处理后端;将听觉外周模型计算结果与已有文献中外耳传递函数、声激励
              下中耳传递函数和镫骨振速、圆窗激振传递函数、内耳基底膜选频特性、频响特性和位移的试验数据进行对比,验证了听觉外
              周模型的可靠性;将响度模型计算结果与等响曲线、带宽噪声响度、频域掩蔽下纯音响度级和复音阈值已有文献中的试验数据
              进行对比,验证了响度模型的可靠性。研究结果表明,该人耳生理响度模型较为准确地计算出了声激励和圆窗激振下基底膜
              振速,并能够用于计算声激励和圆窗激振下纯音、复音和带宽噪声的响度。

              Abstract:  Since  current  loudness  models  are  unable  to  predict  loudness  under  round  window  stimulation,  a  loudness  model  for
              round window stimulation is proposed in this paper. The loudness model consists of a peripheral auditory model and a data process‑
              ing back-end. The peripheral auditory model that is able to calculate basilar membrane velocities under free-field acoustic stimula‑
              tion and round window stimulation and the back-end that transforms basilar membrane velocities into loudness are constructed. The
              reliability of the peripheral auditory model is verified by comparing the model-predicted results with the experimental data on the
              outer ear transfer function, middle ear transfer function and stapes velocities under acoustic stimulation, round window stimulation
              transfer function, frequency selectivity and frequency response of the basilar membrane, and basilar membrane displacement. The
              reliability of the loudness model is verified by comparing the model-predicted results with the experimental data on equal-loudness
              contours, bandwidth noise loudness, loudness level of tone with frequency masking, and threshold for complex tones. The results
              indicate  that  the  loudness  model  accurately  calculates  basilar  membrane  velocities  under  acoustic  stimulation  and  round  window
              stimulation, and is able to predict the loudness of pure tone, complex tones, and bandwidth noise under acoustic stimulation and
              round window stimulation.
