DetailsHearing is very complex, consisting of an elaborate series of events that occur in the ear. In hearing, sound waves in the ear are converted to electric signals that can be transmitted through neurons to the brain.
Hearing Fact SheetCheck out the fact sheet on hearing on the left, provided by the Dana Foundation.
Hair CellsHair cells are the main sensory receptors in the process of hearing. Hair cells are located along the basilar membrane in the cochlea, which vibrates up and down with sound waves. The cochlea is the snail-shaped region of the ear, consisting of two membranes. When the basilar membrane vibrates against the tectorial membrane, the hair cells bend, letting potassium ion fluid in, causing signals to be transmitted.

The ear is a sound-detecting organ that sends signals based on auditory stimulus to the brain through the cochlear nerve.

The outer ear funnels the sound energy to the eardrum, which pushes on bones in the middle ear. The bones in the middle ear, the malleus, incus, and stapes, convert air vibrations to vibrations in fluid to pass signal through the hair cells and cochlear nerve.
