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 (OHC) which increases the amplitude and frequency selectivity of sound vibrations using electromechanical … Visa mer The cochlear amplifier was first proposed in 1948 by Gold. This was around the time when Georg von Békésy was publishing articles observing the propagation of passive travelling waves in the dead cochlea Visa mer Effect of sound waves on the cochlea In the mammalian cochlea, wave amplification occurs via the outer hair cells of the organ of Corti. These cells sit directly above a basilar membrane (BM) that has high sensitivity for differences in frequency. Sound … Visa mer
