Total or significant loss of hearing.
Deafness is usually the result of inner ear or nerve damage. It may be caused by a congenital defect, injury, disease, certain medication, exposure to loud noise or age-related wear and tear.
The chief symptom is an inability to hear sound.
For some, hearing may be possible with surgery or a hearing device. Lip-reading skills, written or printed text and sign language may help with communication.
