What's The Loudest Possible Sound?

If a tree falls in the forest and no person is around, does it still make a sound? Students view a short video segment to determine sound and decibel levels of various objects, including the loudest and quietest possible sounds humans are capable of hearing. They also explore decibel measurement and discuss the effects of not having the ability to hear.
