Abstract
In this paper, a new nonlinear dynamic cochlear model is proposed based on I/O curve. The feedback path of cochlea is simulated by forward feedback model. Two time constants are used for two different adaptation mechanisms, one is used for cochlea adapting its gain from lower stimulation intensity to higher stimulation intensity, another is used for cochlea adapting its gain from higher stimulation intensity to lower stimulation intensity. Experimental results from psychology is used to fix this model parameters. With this model, forward masking effect can be predicted well, also nonlinear and dynamic characters of real auditory system can be predicted, such as nonlinear compression to different stimulation intensity, onset, off set etc.
