    Description

    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
    prostheses.
