James Kates
James M. Kates was born in Brookline,
Mass, in 1948. He received the degrees
of B.S.E.E. and M.S.E.E. from the Massachusetts
Institute of Technology (MIT) in
1971, and the professional degree of Electrical
Engineer from MIT in 1972. He currently
is a Senior Research Engineer in the
Algorithm Development Group of GN ReSound.
He has an office in Boulder, Colo,
where he is involved in research and development
of digital signal processing for hearing aids. He is also an
Adjunct Professor in the Department of Speech, Language & Hearing
Sciences at the University of Colorado at Boulder, where he
conducts research in auditory perception, hearing loss, and signal
processing for hearing aids. Prior to moving to Boulder, he was
with the Center for Research in Speech and Hearing Sciences of
the City University of New York, where he conducted research in
hearing aids and auditory perception. Previous positions include
research and development for hearing aids (Cirrus Logic, AudioLogic,
and Siemens Hearing Instruments), signal processing for
radar, speech, and hearing applications (SIGNATRON Inc.), and
loudspeaker design and signal processing for audio applications
(Acoustic Research and CBS Laboratories).
