Individuals are often curious about statistics involving Deafness. Although statistics are constantly changing, and only a limited amount of surveys have been done on Deafness, we have gathered many of the commonly accepted statistics. Statistics are sited in [ ] when possible.

  • 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.
