The Notion of Sound

[MyWordsAreLaw]

I demand you answer this.

[Wingette]

Define sound.

Macquarie defines it as :

"The sensation produced in the organs of hearing when certain vibrations (soundwaves) are caused in the surrounding air or other elastic medium, as by a vibrating body."

Therefore, there would be no noticeable sound. However, would the vibrations not carry all the way through to someone's ears (considering there no total loss of energy), thereby creating a miniscule amount of sound?

Consider.

Hmm, very interesting prospect here.

Well I agree that for there to be sound, there has to be someone to actually detect it. But how do we even know that the unobserved world acts the same as the observed world? Of course, we generally assume that an observer would not change whether the tree caused a sound or not, but this is impossible to prove beyond doubt. This is where a situation such as that with Schrödinger's Cat arise, where an event is in a suspension of states until it is observed.

[Wingette]

Or is there a multiplex of possible outcomes, and our observation forces upon our universe one pathway?

[ChairmanWalker]

I'm not sure, I am no expert in the field. However, there has to be some variety in available results surely, otherwise the whole Schrödinger's Cat gambit is irrelevant.

[Wingette]

I mean ultimately Schro's cat is just a theory that really doesn't have tangible evidence....isn't it?
