​Aquired causes of Deafness:​
-
Infectious diseases such as Meningitis, Measles and Mumps can lead to hearing loss, mostly in childhood, but also later in life.
-
Chronic ear infection, which commonly presents as discharging ears, can lead to hearing loss. In certain cases this condition can also lead to serious, life-threatening complications, such as brain abscesses or meningitis.
-
Collection of fluid in the ear (otitis media) can cause hearing loss.
-
Use of ototoxic drugs at any age, such as some antibiotic and antimalarial medicines for example, can damage the inner ear.

Head injury or injury to the ear can cause hearing loss.
-
Excessive noise, including working with noisy machinery, and exposure to loud music or other loud noises, such as gunfire or explosions, can harm a person’s hearing.
-
Age-related hearing loss (presbycusis) is caused by degeneration of sensory cells.
