Brian C J Moore"Hearing loss and hearing aids"

Abstract :


Hearing loss affects more than 10% of the adult population in most countries, and is especially prevalent among the elderly.
The most common form of hearing loss arises from dysfunction of the cochlea in the inner ear.  In most cases, the only form of treatment is via hearing aids or (for profound losses) cochlear implants.  In this lecture I will review some of the perceptual consequences of hearing loss, which involve much more than just loss of sensitivity to weak sounds.  Simulations of some aspects of hearing loss will be presented. I will then describe the signal processing that is performed in hearing aids and will consider the extent to which hearing aids “compensate” for hearing loss. Possible avenues for the future will be discussed.

Scientific focus :

He is currently Professor of Auditory Perception in the University of Cambridge. He has also been a Visiting Professor at Brooklyn College, the City University of New York, and the University of California at Berkeley and was a van Houten Fellow at the Institute for Perception Research, Eindhoven, the Netherlands. His research interests are: the perception of sound; mechanisms of normal hearing and hearing impairments; relationship of auditory abilities to speech perception; design of signal processing hearing aids for sensorineural hearing loss; methods for fitting hearing aids to the individual; design and specification of high-fidelity sound-reproducing equipment; perception of music and of musical instruments.
