具有制动机制的基底膜振动的布朗贮能模型
A Brownian Energy Depot Model of the Basilar Membrane Oscillation with a Braking Mechanism
摘要：
高听觉灵敏度、尖锐的频率选择性和耳声发射是耳蜗主动放大的特征。人耳也可以探测到非常大振幅的声音，只要暴露时间不太长，也不会受到损伤。外毛细胞被认为是哺乳动物耳蜗主动力发生器的最佳候选者。在本文中，我们提出了一个新的模型，成功地描述了积极的和保护机制，采用能量储备的概念和临界速度的基底膜的基底膜振荡。主要结果之一是，在没有外部刺激的情况下，热噪声可以被放大，导致自发的基底膜振荡。基底膜在特征频率处的压缩响应和对刺激的动态响应与预期的实验结果一致。我们的模型还显示了基底膜的响应的非线性失真。
英文摘要：
High auditory sensitivity, sharp frequency selectivity, and otoacoustic emissions are signatures of active amplification of the cochlea. The human ear can also detect very large amplitude sound without being damaged as long as the exposed time is not too long. The outer hair cells are believed as the best candidate for the active force generator of the mammalian cochlea. In this paper, we propose a new model for the basilar membrane oscillation which successfully describes both the active and the protective mechanisms by employing an energy depot concept and a critical velocity of the basilar membrane. One of the main results is that thermal noise in the absence of external stimulation can be amplified leading to the spontaneous basilar membrane oscillation. The compressive response of the basilar membrane at the characteristic frequency and the dynamic response to the stimulation are consistent with the experimental results as expected. Our model also shows the nonlinear distortion of the response of the basilar membrane.
