What six basic steps are involved in the process of hearing?
(1 ) Sound waves arrive at the tympanic membrane.
(2 ) Movement of the tympanic membrane causes displacement of the auditory ossicles.

(4 ) The pressure waves distort the basilar membrane on their way to the round window of the tympanic duct.
(5 ) Vibration of the basilar membrane causes vibration of hair cells and bending of stereocilia against the tectorial membrane.
(6 ) Information about the region and intensity of stimulation is relayed to the brain stem over the cochlear branch of N VIII.
