Why do seashells sound like the ocean?
A seashell catches soft sounds around you and makes them bounce inside.

Pip’s answer
- A seashell catches soft sounds around you and makes them bounce inside.
- Those little sounds swirl round and round the curly shell.
- The swirly sounds mix into a soft whoosh, just like waves. Whooosh!
- Ooh, even a cup by your ear can make a little whoosh!
Try it together
Can you cup your hand by your ear and listen?
For grown-ups
The 'ocean' you hear in a seashell is actually ambient noise around you. The shell's curved, hollow shape resonates and amplifies certain sound frequencies, creating a whooshing sound like waves. A cup or your cupped hand works similarly.
Ask your child: Does the whoosh change if you listen to a shell in a quiet room?
