...A row of approximately 3,500 inner hair cells (IHC’s) are situated along the basilar membrane, picking up the resonances generated by the incoming waves. The inner hair cells are spread out exponentially over the 3.4 centimetre length of the tube - with many more hair cells at the beginning (high frequencies) than at the end (low frequencies). Each inner hair cell picks up the vibrations of the membrane at a particular point - thus tuned to a particular frequency. The ‘highest’ hair cell is at 20 kHz, the ‘lowes
