Answer:
losses of hearing
Explanation:
aging and exposure to loud noise may cause wear and tear on the hairs of nerve cell in cochlea that send sound signals to the brain . when these hairs or nerve cells are damaged or missing, electrical signals aren't transmitted as efficiently and hearing loss occurs. hearing loss that occurs gradually as you age (presbycusics) is common. almost half the people in the United States older than age 65 have some degree of hearing loss
