Ear type circuit and system simulating the auditory brainstem response for auditory disorder characterization

A use of auditory brainstem response in auditory disorder diagnosis is investigated in this paper leading to a proposed characterization method of the human auditory system. A modified nonlinear continuous time Hopfield neural type system is able to model the system yielding the simulated response in good agreement with the measured one. Both Simulink and PSpice simulation are investigated as well as the implementation of the system using a transistorized circuit. This opens a new possibility in improved means of noninvasive correction of auditory disorder which can be developed as the very large scale integrated hearing aid type chip.
