DEMO_VERHULST2015 - Demo of the cochlear model calculating otoacoustic emissions

Description:

This script computes and plot the otoacoustic emission for a 500 Hz sinusoid, This is generated using the cochlear model described in verhulst2015. In particular otoacoustic emissions are computed as the signal difference between the sound pressure at the middle ear with model nonlinearities and irregularities enabled, and the sound pressure at the middle ear in case of linear model.
