Research Interests
Professor Eddington’s research is directed at improving the
hearing provided the deaf by cochlear implants. These devices deliver
electric stimuli to remaining auditory-nerve fibers using electrodes
implanted in the inner ear. An external sound processor translates
sound to instructions that control the implanted stimulator. The
patterns of stimuli delivered to the implanted electrodes determine
the sound sensations elicited. Professor Eddington’s work
includes: (1) using computer models of the implanted inner ear to
identify peripheral anatomical and physiological factors that limit
performance, (2) using psychophysical measures of performance in
implanted human subjects to also identify factors that limit performance
and (3) designing and testing new sound-processing strategies to
overcome the limiting factors identified in (1) and (2) to produce
clearer hearing.
