Why do you hear the ocean echo from a shell?

The larger the seashell the louder the sound, right? It is the space inside the shell that creates the sound. Well, the space inside the seashell bouncing against the sounds of your surroundings.

For the most part people are experimenting with this seashell symphony at the beach where there is a lot of  space for sounds to resonate inside the seashell.

It would be the same type of sound when you put a glass up to your ear. It you put a glass up to your ear in the bathroom with the door shut you will hear very little. If you put the glass up to your ear outside, you will hear the “ocean”.
