Okay, I'm probably not going to explain myself very well, but I'm going to try, and whoever can understand what I'm trying to ask gets 10000 internet points.
Say you hit a tuning fork and recorded the sound. If you had whatever equipment you required, could you determine, from that one sound, where the sound originated on earth. I'm wondering, if you had the means to examine the sound at it's most minute details, would it be unique to one spot on earth?
Would atmospheric pressure, altitude, density, pollution (or any other variable). . . etc etc influence pitch (even if not detected without the most sensitive equipment?)
Gha - I'm going to regret posting this, aren't I? I'm going to reveal myself to be a real science idiot :\
