A weeks ago or so T.J. and I got to talking about "If a tree falls in the forest, and no one is around, does it still make a sound?" I said yes, but TJ. said no. And I have to say, he's right.
It wont make a sound. If no one is around (Be it a person, bird, mouse, or anything with an ear) then there is only vibration and vibration does not make sound. It's the ears that pick up the vibration and translates that in to sound that we can make sense of.
I know, you all out there probably already thought this one out.
