Ive always wondered what would happen if you lined up 10 megaphones in a row and yell into them, today I put that idea to the test! That literal feedback loop was crazy loud!

THAT IS ONE AWESOME VIDEO WITH BART SIMPSON!!!
I've been watching the Simpsons since I was a kid too!

Since you also have sound level-meter, 0:41, It'd be cool for me to try and use whenever I buy some Megaphones too.

Besides Megaphones, would it be fair to use the sound level-meter with microphone(s) too?
Terry Pold
Interesting side note about the speed of sound in denser materials. In a black hole the speed of sound equals the speed of light.
