Current work:

Cochlear implants have achieved great success as a sensory prosthesis for the severely or profoundly hearing-impaired. By electrically stimulating select areas of the hearing nerve, a cochlear implant delivers sufficient speech information to most listeners. However, the devices are as yet limited in their ability to deliver the fine-grained time-frequency information that is necessary for the appreciation of the musical aspects of sound, or for listening in noise. This project aims to quantify the sensitivity of the cochlear-implanted auditory brain to time-frequency patterns of sound information, and to relate the findings to patients' performance in everyday listening situations. In particular, we focus on issues related to improved coding of voice or musical pitch information and listening in noise. The findings are expected to enhance knowledge of auditory processing mechanisms in the brain, as well as to contribute to the development of future generations of cochlear implant systems.
