Use of Auditory Models in Developing Coding Strategies for Cochlear Implants

Auditory models are used at least to some extent in all current designs of cochlear implant (CI) systems. For example, all current designs use a filter bank to mimic in a coarse way the filtering that occurs in the normal auditory periphery. However, the models used are relatively simple and do not include the intricacies of the ­normal processing or the interactions (e.g., feedback loops) among processing steps.
