Analysis of Coding Strategies in Cochlear Implant Systems

This article is about the structure and principle of operation of cochlear implant systems as unique high-tech devices that allow people, regardless of their age, to compensate for partial or complete hearing loss; it features the fitting session of a significant component - a sound processor that converts acoustic signals into electrical impulses. It mentions about the cochlear implant systems used in the world, as well as in Russia, the signal coding strategies developed and implemented in these devices. Two ways have been identified for further development of research into signal distortions in these systems, taking into account the analysis of scientific literature and the practical experience of the authors when interacting with users of cochlear implant systems. They are the creation of new signal coding strategies and stimulation algorithms that improve the perception of sounds in various acoustic environments (noise of varying intensity, wind, quiet, speech of interlocutors in noise) and experiments with users systems within already created coding strategies and stimulation algorithms.
