Any source of sound sends vibrations or sound waves into the air. These funnel through the ear opening, down the ear canal, and strike the eardrum, causing it to vibrate.
The vibrations are passed to the smaller bones of the middle ear, which transmit them to the hearing nerves in the inner ear.
There, the vibrations of the hair cells activate the nerves connected to the brain, which interprets the impulses as sound: music, a slamming door, a voice etc.
When noise is too loud, it begins to kill the hair cells in the inner ear.
As the exposure time to loud noise increases, more and more nerve endings are destroyed.
As the number of nerve endings decrease, so does your hearing.
There is no way to restore life to dead nerve endings; The damage is permanent.
