Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible. However, both birds and fish are able to re-grow the damaged hair cells and restore hearing. New research shows that growth hormone is involved in this regeneration in zebrafish.
