This paper describes the implementation and performance of a nonlinear time-domain model of the cochlea for transient stimulation and human otoacoustic emission generation. The nonlinearity simulates compressive growth of measured basilar-membrane impulse responses. The model accounts for reflection and distortion-source otoacoustic emissions (OAEs) and simulates spontaneous OAEs through manipulation of the middle-ear reflectance. The model was calibrated using human psychoacoustical and otoacoustic tuning parameters. It can be used to investigate time-dependent properties of cochlear mechanics and the generator mechanisms of otoacoustic emissions. Furthermore, the model provides a suitable preprocessor for human auditory perception models where realistic cochlear excitation patterns are desired.
本文描述了一个用于瞬态刺激和人耳声发射产生的耳蜗非线性时域模型的实现和性能。该非线性模型模拟了测量基底膜脉冲响应的压缩增长。该模型通过对中耳反射率的操作来解释反射和失真源耳声发射（OAE）并模拟自发耳声发射。该模型使用人体心理声学和耳声调谐参数进行校准。它可用于研究耳蜗力学的时变特性和耳声发射的产生机制。此外，该模型为希望获得真实耳蜗激励模式的人类听觉感知模型提供了合适的预处理程序。
