If a 树 falls in the middle of the forest and no-one is around to hear it does it make a sound?

Not if Kanye West is around to interupt it.

Well, if a tree-hugger was nearby then you'd probably hear something.

The only sound i would hear is the agony and pain after the 树 fell on the wildlife animals. Lol.:D
Does that count?

Yes it makes a sound because of the soundwaves that would be created as it fell and hit the ground. that's the thing with humans- think they're so damn special that falling trees decide not to make a noise because theyre not there to hear it
;) lol

I hate this one.

People say it doesn't because 你 are not there to hear it....
Stupid.

你 know well enough that a big 屁股 树 collapsing in the woods would make a sound, whether 你 are there 或者 not. ._.
