Representation of adaptive tinnitus suppression mechanism in an adaptive cochlear model

Tinnitus is the perception of phantom sounds in the ears or in the head without external sound sources even in the completely silent environment. There is no known effective medical treatment for tinnitus and acoustic masking has provided patients with some measure of relief. In this paper adaptive treatment method with acoustic stimulation has been investigated and simulated by means of an adaptive model for cochlea and color noise performances are compared with the pure tone suppressor to extract the best types of acoustic stimulation methods and their ranges for tinnitus treatment. Simulation results are confirmed by clinical and physiological reports.
