Auditory cellular cooperativity probed via spontaneous otoacoustic emissions.

ABSTRACT: As a sound pressure detector that uses energy to boost both its sensitivity and selectivity, the inner ear is an active nonequilibrium system. The collective processes of the inner ear that give rise to this exquisite functionality remain poorly understood. One manifestation of the active ear across the animal kingdom is the presence of spontaneous otoacoustic emission (SOAE), idiosyncratic arrays of spectral peaks that can be measured using a sensitive microphone in the ear canal. Current SOAE models attempt to explain how multiple peaks arise, and generally assume a spatially distributed tonotopic system. However, the nature of the generators, their coupling, and the role of noise (e.g., Brownian motion) are hotly debated, especially given the inner ear morphological diversity across ver
