Implementation of Spectral Maxima Sound Processing for Cochlear Implants by Using Bark Scale Frequency Band Partition

Abstract

A new method on the basis of Bark scale frequency-band partition was presented to improve the recognition performance of cochlear implants. in the nature of physics, it consists with human's cochlea filter properties. Also the mechanism of a cochlear implant and its spectral maxima sound processing (SMSP) strategy were presented. The time frequency analyzing property of human's cochlea was analyzed. The theoretical determination of Bark scale frequency-band was also given with formula. Simulation results using Bark scale transform signal processing were discussed in detail and results show that the new method is feasible in speech processors for cochlear implants.
