Analysis and Development of Techniques and Methods in Medical Practice in Cochlear Implant Systems
Cochlear implant methods are the area of interest and intensive medical and technical efforts for investigations, analysis, implementation, testing and finally producing more and more precise and effective cochlear implant prosthesis. The goals of this article are first to present the cochlear implant system in historical plan, then to analyze some of the existing signal processing strategies in cochlear implant systems, which leads to the decision of the importance of filter bank design for the precision of the signal processing in the cochlear implant algorithms and practical implementations. It is presented a detailed description and critical comparison of the most useful types of cochlear filter banks and as the results from the analysis some useful conclusion are presented for the cochlear filter banks characteristics, time consuming in calculation, the importance for overall cochlear implants quality of speech sound processing, etc. The defined in conclusion assertions are accepted as the basis of future investigations in area of new cochlear implant model development.
