Here are two simple ways to say how hearing works:
Way 1 — Step by step
- Something makes a sound and the air around it wiggles (these are sound waves).
- Your outer ear (the part you can see) catches the wiggles and sends them to the eardrum.
- The eardrum shakes and moves three tiny bones in the middle ear.
- Those tiny bones push the shaking into the cochlea, a small spiral tube like a snail shell.
- Inside the cochlea the shaking becomes signals that nerve cells can understand.
- The nerves carry the signals to your brain, and your brain tells you what you heard.
Way 2 — Short and simple
- Noise makes invisible ripples in the air.
- The outer ear sends the ripples to the eardrum, which wiggles.
- Three tiny bones pass the wiggle into the snail-shaped cochlea.
- The cochlea turns the wiggle into nerve messages.
- The nerves bring the messages to your brain, and you hear the sound.
