Effect of the Number of Maxima and Stimulation Rate on Phoneme Perception Patterns Using Cochlear Implant Simulation

Over the past few decades, cochlear implants (CIs) have become an alternate solution to hearing aids for people with severe-to-profound sensorineural hearing loss. Despite scientists’ continuous efforts to facilitate hearing ability, however, there are still unresolved issues that CI users’ experience (e.g., fine speech perception, speech perception in noise, and music perception). When CI patients complain about these issues, one of the primary methods audiologists can employ is to adjust the mapping parameters to resolve their perceptual complaints. Numerous investigations have studied changes in signal processing strategies Purpose: Maximizing speech perception for cochlear implant (CI) users can be achieved by adjusting mapping parameters. The object of this study was to investigate optimal sets of parameters of stimulation rate and the number of maxima in the CI system.
