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.
