Answer:
Once hearing is damaged, it often can’t be restored. Some of the many causes of hearing damage include:
noise – sound is picked up by a small, spiral-shaped organ called the cochlea that is located within the inner ear. Thousands of tiny hairs in the cochlea sense the vibration and pass the message to the brain via the cochlear nerve. These sensitive hairs can be damaged by excessive noise. Ringing in the ears (tinnitus) after exposure to loud noise is a warning sign that your ears have been overloaded
medications – certain chemicals and medications can damage your hearing
disease – some diseases, such as measles, mumps, rubella (German measles) and meningitis, can cause loss of hearing
injury – including perforation of the ear drum, fractured skull or large changes in air pressure (barotrauma).
