1 in 1000

Hearing loss remains the most common disability diagnosed at birth. The incidence has stayed steady over the years and rises from 1 in 1000 at birth to 1 in 300 by school age (due to acquired and developing hearing loss).

3. What in the cochlear helps you hear?
Tiny hairs

Your sense of hearing depends on tiny hairs deep inside your ear. If you lose these hairs, you lose your hearing.

4. When do your ears stop hearing?

Your ears never stop hearing, even when you sleep. Your brain just ignores incoming sounds.

5. What else do our ears do other than help us hear?

The ear is one of the sensory organs that help us to hear. An interesting point to note is that the ear not only helps in hearing but also helps us to maintain the balance and equilibrium of our body. Without the ear, we would not be able to balance our body with respect to the gravitational pull of the earth.

The mammalian middle ear contains three small bones, which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.

7. As you get older you become less able to hear

8. Ringing in the ears is a sign of hearing loss

Up to 90% of people with tinnitus have some level of noise-induced hearing loss. The noise causes permanent damage to the sound-sensitive cells of the cochlea, a spiral-shaped organ in the inner ear.
