Project Details


The processes within the cochlea which enable it to achieve its high
sensitivity and sharp frequency selectivity are still largely unknown. The
primary goal of the research proposed here is to improve our understanding
of cochlear function by developing a realistic mathematical model of
cochlear mechanics. This model development will involve the formulation of
hypotheses concerning cochlear function which will be tested by comparing
numerical solutions of the model with experimental observations published
by other researchers. Among the major objectives are: 1) an investigation
of the possible role that active elements within the cochlea may play in
boosting the sensitivity and frequency selectivity and frequency
selectivity of basilar membrane displacements; and 2) a description of the
changes in model parameters that correlate with common hearing impairments
or normal developmental gradients. A secondary goal of the proposed
research is the development of computer algorithms which simulate the
frequency analysis of the cochlea and are fast enough to be considered for
use in applications such as speech spectrograms or cochlear implant
