Why you can hear the ocean in a seashell?
One theary people have
Some people have said that the sound you hear from the seashell is the echoing of your blood rushing through the blood vessels of your ear. But that's not the case. If it were true, then the sound would increase, after exercising, since your blood races at faster after exercising.
The truth is that the wooshing sound you hear inside a seashell is genarated by air flowing in and out of the shell that creates a sound that sounds like the ocean. You will see that the noise gets louder when you lift the shell a little bit above your ear because there is more air echoing in the shell.
