Role- Co-Investigator Coulter Foundation Grant - Dennis Barbour (PI) 8/06 7/07 Improvement of Noisy Signal Representation in Auditory Prostheses via Biologically Inspired Spectral Contrast Shaping. The major goal of this project was to test a biologically inspired noise reduction strategy in adult cochlear implant users. Role-Co-Investigator Research support for doctoral dissertation provided by the following corporations: Advanced Bionics, Cochlear Americas, Oticon, Widex and Westar, 08/01/02-08/01/03-$26,000 Comparing the Speech Perception Abilities of Children with Cochlear Implants and Digital Hearing Aids. The aim of this study was to determine the unaided pure-tone average value above which a child with digital hearing aids would exhibit significantly better speech perception with a cochlear implant.
