That's arguable, but "purpose" has nothing to do with whether or not the sound waves are actually there.
If you asked a deaf person if they heard the tree fall in the forest, they would say the tree made no sound. He is not lying, nor is he mis-informed. His eardrums are non-functioning.
Correct, but that doesn't mean the sound isn't there. If a blind person can't see a sign, it doesn't mean it's not there.
Until that little membrane is present and functioning, there is no sound.
Nope, the sound is there whether or not someone is there to hear it or whether or not someone is deaf.
