Find out how the ear and brain work together to let people hear.

How does it work?

  • There are lots of different bits to your ear. Most of them are hidden inside your head!

  • Sound travels along the ear by making it wobble.

  • The back of the ear sends information up to your brain.

  • The brain then makes sense of what you can hear!

Why do we have earwax?

  • It protects the body by trapping dirt and germs that enter the ear.
