If A Tree Falls...
If a tree falls in the middle of a forest and no one is around to hear it, does it make a sound? Cognitive psychologists would overwhelmingly resound "no"! For a sound to exist one would have to perceive it, and with no perception, there are only unsuspecting molecules being moved. The movement of said molecules could theoretically be perceived in any way. With sound being the sensation excited in the ear itself. If there are no ears or sort of input to take in the vibration of air, there is no sound.
While another argument deal with if an tree cannot exist without a being perceived, this does not not help with our problem at all, and we would not ever say that a particular tree behind us no longer exists because it is now outside our field of view. The falling tree existent or not, produces vibration of air.
