How come we can hear the ocean in a seashell?

Answer 1

Its not actually the ocean we hear (though it does sound like it).

What we hear in a seashell is the sound of the blood moving through our body (particularly in the head area), amplified and reflected back to the ear by the shell.
It sounds like waves because the heart beats and with each beat there is a surge of blood through the blood vessels, and the shell amplifies the noise that blood makes as it moves through the small blood vessels.

Answer 2

its not the ocean at all

you know how you lay ur head on someones tummy
and can hear sounds. well same goes for the ear.
there is always noise in it. the seashell is kinda like
a stethoscope. the noise in ur ears echo off the walls
of the seashell, thus making an "ocean" sound
