Cochlear models - 1978.

J B Allen

    Scandinavian Audiology. Supplementum
    |January 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Cochlear models require nonlinear basilar membrane mechanics and a second-filtering mechanism for accurate hearing system simulation. Research also explores dimensionality and analytical methods for frequency analysis.
