Frequency Transformations and Spectral Gaps in Cochlear Implant Processing

This paper clarifies and extends previous findings on frequency distortion in cochlear implants, showing how nonlinear processing leads to spectral gaps, frequency transformations, and intermodulation products that impair sound perception.

An Analysis of Cochlear Implant Distortion from a User’s Perspective

The paper analyzes cochlear implant distortion from a user's perspective, identifying envelope-based signal processing as the primary cause of unpleasant distortion and suggesting improvements.
