Answer 2

Answer:

How hearing loss can occur

Causes of hearing loss include:

Damage to the inner ear. Aging and exposure to loud noise may cause wear and tear on the hairs or nerve cells in the 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.

Higher pitched tones may become muffled to you. It may become difficult for you to pick out words against background noise.

Gradual buildup of earwax. Earwax can block the ear canal and prevent conduction of sound waves. Earwax removal can help restore your hearing.

Ear infection and abnormal bone growths or tumors. In the outer or middle ear, any of these can cause hearing loss

Ruptured eardrum (tympanic membrane perforation). Loud blasts of noise, sudden changes in pressure, poking your eardrum with an object and infection can cause your eardrum to rupture and affect your hearing.
