Objective:

This project investigates the effect on cochlear implant (CI) speech understanding caused by spectral peaks and notches, such as those resulting from the head-related transfer function filtering of a sound source. This is required to determine how spectral localization cues are best encoded with CIs, without destroying speech information.

Application:

Results from this project are required for the development of a 3-D localization strategy for CIs. Furthermore, the results give insight into the robustness of speech cues against spectral disruption in electric hearing.
