Numerical techniques are used to explore the influence on the predicted basilar membrane (BM) response of the position of the nonlinearity within the micromechanical feedback loop of an active nonlinear cochlear model. This position is found to influence both the harmonic and distortion product spectra of the predicted BM response. The BM motion at the fundamental or primary frequencies is not significantly altered by the position of the nonlinearity, however, provided that the gain is appropriately adjusted. The observed effects are explained in terms of the frequency responses of the elements within the micromechanical feedback loop.
数值技术被用于探究非线性在主动非线性耳蜗模型的微力学反馈回路中的位置对预测基底膜（BM）响应的影响。该位置被发现同时影响预测 BM 响应的谐波和失真产物谱。然而，只要增益被适当调整，BM 在基本或主要频率处的运动就不会受到非线性位置的显著影响。所观察到的效果可以根据微力学反馈回路中的元件的频率响应来解释。
