ⓘ Cochlear amplifier

The cochlear amplifier is a positive feedback mechanism within the cochlea that provides acute sensitivity in the mammalian auditory system. The main component of the cochlear amplifier is the outer hair cell which increases the amplitude and frequency selectivity of sound vibrations using electromechanical feedback.
