非线性耳蜗力学模型和偏移技术解法
NONLINEAR COCHLEAR MECHANICAL MODEL AND ITS BIAS TECHNIQUE
-
摘要: 本文建立了二维非线性耳蜗力学模型,并提出一种有效方法偏移技术来求解该模型。模拟结果表明,该模型较好地表征了一些生理学实验资料,如基底膜不同位置有不同的谐振频率和一些非线性特性,如位置的频率响应与输入强度有关的非线性特性。

Abstract: The nonlinear equation modeling the 2-D cochlear mechanics is established,and an effective method-bias technique for computing this equation is presented. The modelshows many effects which correlate closely to physiological counterparts. The quantitative data on the level-dependence of frequency responses are given. -
