The ocean inside a seashell

A friend of mine collects seashells, and as I held one of them to my ear I was mindful of the sounds I heard. Since I was little, I noticed that it sounded a little bit like the sounds of the ocean.  The sounds that we hear are actually the sounds around us that are captured by the shell and then resonate. Different seashells create different noises because they emphasize different frequencies. The sound enters the shell, bounces inside it and resonates back, creating that "ocean" noise that we hear.
