"If a tree falls in a forest and no one is around to hear it, does it make a sound?"
The answer to this question depends on the definition of sound. Since sound does not exist without our hearing of it, sound does not exist if we do not hear it. However, when a tree falls, the motion disturbs the air and sends off air waves.
