James B. Dewey, PhD

The Dewey Lab studies the mechanical processes that underlie normal hearing and how these processes are affected in hearing-impaired ears. Current topics of investigation include (1) how sound causes the structures within the cochlear spiral to vibrate, (2) how these vibrations are amplified by the sensory outer hair cells, and (3) how this amplification process leads to the emission of sound by the ear.
