The recent discovery of oto-acoustic emissions [see Zurek, J. Acoust. Soc. Am. 78, 340-344 (1985)] and the newer measures of the micromechanics of the inner ear have generated renewed interest in quantitative descriptions of the biomechanics of the cochlea. Active elements (mechanical force generators) are thought to be essential for producing the high sensitivity and sharp tuning typically associated with normal cochlear function. A mechanical model with active elements is described which can simulate basilar membrane displacements with neural-like tuning and peak amplitudes of about 1 nm at the threshold of hearing. In addition, such models might help explain the source of oto-acoustic emissions. The paper describes the power of the recent attempts at providing quantitative descriptions and predictions of the mechanics of the cochlea.
耳声发射的最新发现[见祖雷克，《美国声学学会杂志》78, 340 - 344 (1985)]以及内耳微力学的更新测量方法，重新引发了人们对耳蜗生物力学定量描述的兴趣。活性元件（机械力发生器）被认为对于产生通常与正常耳蜗功能相关的高灵敏度和尖锐调谐至关重要。本文描述了一个具有活性元件的力学模型，该模型能够以类似神经的调谐方式模拟基底膜位移，并且在听力阈值处的峰值振幅约为1纳米。此外，此类模型可能有助于解释耳声发射的来源。本文阐述了近期在对耳蜗力学进行定量描述和预测方面所做尝试的作用。
