FACTS ABOUT HEARING

Malleus Bone

#1. Fish do not have ears, but they can hear pressure changes through ridges on their body.

#2. The ear’s malleus, incus and stapes (otherwise known as the hammer, anvil and stirrup) are the smallest bones in the human body. All three together could fit together on a penny.

#3. The ear continues to hear sounds, even while you sleep.

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

Incus Bone

#5. Dogs can hear much higher frequencies than humans.

#6. Ears not only help you hear, but also aid in balance.

#7. Snakes hear through the jaw bone and through a traditional inner ear. In essence, snakes have two distinct
hearing mechanisms, which helps them hear and catch prey.

Stapes Bone

#8. Sitting in front of the speakers at a rock concert can expose you to 120 decibels, which will begin to damage hearing in only 7 1/2 minutes.

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