Hair cells are located in the inner ear and rest on the basilar membrane. The cells function to convert pressure waves created by sounds striking the tympanic membrane into electrical impulses. These impulses are normally sent to the brain via the vestibulocochlear nerve. However, if the hair cells never release neurotransmitters due to damage, then the sound is never sent to the brain.
