​ A sea shell is a sound chamber. Ambient waves are sounds that come from the noise around us, which means the sound chambers bounce off the ambient waves. The louder the noise is around you, the louder the ocean noise is going to sound coming from out of the seashell. That should explain why you can hear the ocean in a seashell. An interesting fact or some more information on hearing the ocean in a seashell would be the seashell having many curved hard surfaces, making the seashell a good reflector for sound. For example: Say you were a family get together and there was a lot of talking going on. The sound coming from ambient waves affect the noise in the seashell and the sound of the ocean would be much louder. For example: Say you were all alone in a very quiet area, such as the library. The sound coming from the ambient waves would also affect the noise, so the sound of the ocean would be more quiet and calmer. Depending on whether the noise is loud or very quiet, it will determine how much of the ocean you can hear in the seashell. Notice the curved hard surfaces on the outside of the seashell. You would be able to hear the ocean in the shell depending on the loudness or quietness of the environment you are in.
