This study integrates a non-linear inner hair cell model (IHC) into the computational auditory signal processing and perception (CASP) model [Jepsen, Ewert, and Dau (2008). J. Acoust. Am. 124(1), 422–-438]. The integration addresses limitations of its more simplistic predecessor that did not reflect the saturation of the IHC transduction process towards high sound pressure levels. While exhibiting distinct processing mechanisms compared to the original model, the revised model maintains predictive power across conditions of intensity discrimination, simultaneous and forward masking, and modulation detection, effectively accounting for data from normal-hearing listeners. Additional updates and refinements to the model are introduced in response to the changes produced by the additional compressive non-linearity and to improve its usability. Overall, the revised CASP model offers a more accurate and intuitive framework for simulating auditory processing and perception under diverse conditions and tasks. This enhanced version may be particularly valuable for studying the influence of the ear's nonlinear response properties on internal auditory representations, including the effects of sensorineural hearing loss on auditory perception.
