This paper describes the development of a quantitative auditory model based on a ‘humanized’ nonlinear auditory-nerve model of Zilany and Bruce (2007). The model is able to account for the change in tone-burst evoked ABR latency with frequency, but underestimate changes in both click and tone-burst latency values with stimulus level. However, the model correctly predicts the non-linear ABR amplitude behaviour in response to different chirp stimuli (ref. 15, 16 & 17) and thus supports the hypothesis that the ABR generation is strongly influenced by the non-linear and dispersive processes in the cochlea.
