Abstract :
A computational model for the auditory amplitude modulation encoding is evaluated. This model, based on the physiological organization of the auditory pathway, is implemented on a friendly block-oriented interface using Simulink. We particularly focus on the pathway from the external ear to the cochlear nucleus. The responses of the model to amplitude modulated white Gaussian noise are compared to those observed in the auditory cortex, showing the same low-pass characteristics.
