Hair cells in the cochlea have cilia of varying lengths that resonate to different sound frequencies; their movement depolarizes the cell, generating a nerve impulse transmitted via the auditory nerve, with vibrations dispersed by the round window.

| Front | structure of hair cells |
|---|---|
| Back | ceilia varying in length (each resonating to a different frequency of sound), movement of stereocilia depolarises hair cell to generate a nerve impulse, transmitted via auditory nerve to auditory centres of brain, all movement is dissipated by the vibration of the round window |
