Physiologically active cochlear micromechanics--one source of tinnitus

D T Kemp

    Ciba Foundation Symposium
    |January 1, 1981

    Summary

    Spontaneous cochlear vibrations cause mild tinnitus in many people. Research shows these vibrations relate to cochlear echoes and can be modified, offering insights into tinnitus causes and treatments.

    Area of Science:

    • Otoacoustic Emissions
    • Auditory Neuroscience
    • Biomedical Engineering

    Background:

    • Spontaneous otoacoustic emissions (SOAEs) are audible vibrations in the cochlea.
    • These vibrations are linked to cochlear resonances and feedback mechanisms.
    • Understanding SOAEs is crucial for tinnitus research.

    Purpose of the Study:

    • To investigate the nature of spontaneous cochlear vibrations.
    • To explore the relationship between cochlear vibrations, cochlear resonances, and tinnitus.
    • To identify methods for modifying cochlear mechanical activity.

    Main Methods:

    • Utilized acoustic ear-canal recording techniques to study spontaneous cochlear vibrations.
    • Applied cochlear resonance theory to analyze cochlear mechanical activity.
    • Investigated the effects of middle-ear mobility and brief overstimulation on cochlear activity.

    Main Results:

    • Spontaneous cochlear vibrations are directly related to stimulated acoustic emissions (cochlear echoes).
    • Cochlear resonances, developed via feedback, drive these spontaneous oscillations.
    • Cochlear mechanical activity can be modulated by middle-ear changes or overstimulation, revealing a biphasic recovery cycle.
    • Identified criteria for diagnosing cochlear mechanical tinnitus.

    Conclusions:

    • Spontaneous cochlear vibrations are a source of mild tonal tinnitus, particularly in individuals with normal hearing or middle-ear issues.
    • The identified biphasic recovery cycle may be relevant to temporary noise-induced tinnitus and threshold shifts.
    • Localized oscillations in isolated cochlear elements might cause significant tinnitus without detectable external vibrations.
