Here's one to get the brain cells working:
If a tree falls in a forest and no one is around to hear it, does it make a sound?
What definition of sound are you using? The physics one or the psychology one?

Ugh?
Some very acute original thinking by you there FH.

This is a brilliant answer.
And why have I not heard of dinotracker.com before! (a rhetorical question.) What a site!
"In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain." (Sound - Wikipedia)
I think if its the physics def then the awnser is 'yes'. I thought yes when I first read it and it seemed pretty obvious so I read various articles on sound to know why this is even a question... (spent an hour doing that instead of doing homework.. then another hour on dinotracker.com - anyway)
It's probably using the psychology one. But I don't like that definition..
If I changed the question to: If a deaf person is in a forest and a tree falls, did the tree make sound? - *I* would say that there is still sound (sound happens all the time even if they don't hear it). I don't think anybody claims a deaf persons world is soundless, they just don't process the sounds.
It's also nearly impossible to clear a forest of all hearing creatures.
And there are sounds that some animals hear that humans cannot. Those sounds still exist though.
I cant think of any reason why it wouldn't make sound (maybe unless the forest is somehow a vacuum).
Also, if I set up a camera in the forest before the tree fell, it would record sound (to be played later/heard later). A camera does not have any ears or brains
The psych definition should be the definition of processing sound not sound itself (imo)
[I don't know any of this for fact...just my thoughts]
