Research Topic: Exploiting the “better ear” in bilateral cochlear implants for improved speech understanding in noisy situations and Auditory Processing.
Dr. Kan was also funded for his research in 2014.
Long-Term Goal: To close the gap in speech understanding performance between cochlear implant users and normal hearing listeners. The primary outcome of this study will help determine whether the “better ear” strategy will provide a significant benefit for cochlear implant users, and whether this strategy for listening is desirable.
