To investigate how outer hair cells (OHCs) produce compressive nonlinearity in both the cochlear I/O function and tuning curve for a single tone, we present a nonlinear cochlear model with a nonlinear OHC model. In modeling cochlea filtering, we modeled somatic motility as a function of OHCs and the interaction between the basilar membrane and somatic motility through the tectorial membrane as mechanoelectrical transducer networks. The parameter values of the model were set to the estimates for human data. Signal frequencies of 0.125, 0.25, 0.5, 1, 2, 3, 4, and 6 kHz were used in the simulations of cochlear filtering. The results revealed that this model can account for the compressive nonlinearity in both the I/O functions and tuning curves of a cochlea obtained from the experiments. They also suggest that the somatic motility depending on the transducer currents produces nonlinearities in the I/O functions and tuning curves of cochlea.
