10 Facts About Hearing and Hearing Loss

  1. The smallest bones in the body are found in the middle ear, and there are three of them: the incus, malleus, and the stapes, otherwise known as the anvil, hammer, and the stirrup.

  2. Sound travels at the speed of 1,130 feet per second, or 770 miles per hour.

  3. Thirty-seven percent of children with only minimal hearing loss fail at least one grade.

  4. A 12-year study conducted by the neurology department at Johns Hopkins School of Medicine found that untreated hearing loss increased the risk for dementia.

  5. The inner ear is no larger than a pencil eraser in circumference.

  6. Crickets have their hearing organs on their knees, male mosquitos hear with thousands of tiny hair cells growing from their antennae, and snakes hear through their jawbones.

  7. Individuals with hearing loss wait an average of seven years before seeking help.

  8. Your sense of hearing is dependent on tiny hair cells housed inside the inner ear. Damage to these hair cells results in hearing loss.

  9. Skin glands in the ear canal produce earwax, which helps protect the ear by lubricating it and cleaning it of dirt and dust.

  10. The ears are not only necessary for hearing; they also help with balance.
