Abstract

The research study described here focuses on the evaluation and further development of a cochlear implant (CI) processing strategy called F0mod (Laneau et al., 2006). The strategy facilitates coding of the fundamental frequency (F0) of an acoustical signal in the electrical stimulation pattern. This document presents concepts of the processing algorithm. Furthermore, an overview about the framework of psychophysical experiments with CI subjects covering music and speech perception related tasks will be given.
