Question:
Why does listening to a conch shell sound like listening to the waves of the ocean?

Answer:
No, it is not the sound of the blood flowing through the blood vessels in your ear. Neither is it the sound of air gushing in and out of the shell.

The wave-like sound heard when a conch shell is held close to the ear is nothing but the ambient noise around you. The ambient noise captured in the conch-shell resonates in it creating the sound of the sea waves. The size and complexity of the interior of the shell has an effect on what frequencies of sound are accentuated.

In fact, you don’t even need to have a conch shell to hear the waves. You can hear the same sound by placing your hands in the form of a cup around your ears. Go ahead and try it!
