Spontaneous Otoacoustic Emission Generators Behave Like Coupled Oscillators

Properties of spontaneous otoacoustic emissions (SOAE’s) are such that SOAE generators can best be described by self-sustaining oscillators (Bialek and Wit, 1984). These oscillators are thought to reside in the inner ear, and to be closely related to the hair cell transduction process. In this view this process makes use of positive feedback to enhance frequency selectivity, and SOAE’s are merely a (non-disturbing) by-product, caused by too strong feedback in some of the inner ear active filters.
