What is the sound inside a seashell?
The shape of seashells just happens to make them great amplifiers of ambient noise. Any air that makes its way into a shell’s cavity gets bounced around by its hard, curved inner surfaces. The resonating air produces sound. The pitch of the sound depends on the size of the shell.
What creature lives in a conch shell?

This is because scientists have discovered that a lot of mollusks produce about one new ridge every day.

The sound is resonating in the bottle. You and I might call it a “bottle” — but a physical acoustician would call it a “resonant cavity”. Getting back to our seashell, the inside is hard with an almost-glazed finish — so it’s an excellent reflector of sound (it’s a resonator).
