耳声发射是近年来耳科学领域很受重视的研究课题。本文的目的是从生理系统的仿真与建模的角度研究耳声发射的产生机理。基于电声学等效关系，本文给出了耳蜗的一维非线性传输线模型。该模型中引入非线性受控源做为耳声发射信号的产生源。计算结果表明，该模型除具有与耳蜗生理基本一致的选频特性外，还可成功地仿真两种重要的耳声发射信号、瞬时诱发耳声发射（ＴＥＯＡＥ）及变调失真耳声发射（ＤＰＯＡＥ）。
Otoacoustic emissions in recent years, ear science is a subject of much research. The purpose of this paper is to study the mechanism of otoacoustic emissions from the perspective of physiological system simulation and modeling. Based on the electro-acoustic equivalent relationship, a one-dimensional nonlinear transmission line model of the cochlea is presented in this paper. The model introduces a nonlinear controlled source as a source of otoacoustic emissions. The results show that the model can successfully simulate two important types of otoacoustic emission signals, transient induced otoacoustic emissions (TEOAE) and temporally modulated distortion otoacoustic emissions (DPOAE), in addition to the frequency selective characteristics that are basically the same as the cochlear physiology. .
