@Green Witch,

What I really want to know is if a tree falls in a forest...
OK, if u really wanna know:
if the forest animals (or anyone else)
hears it fall then it makes a sound.
If no one at all hears it,
then
the air will vibrate the same,
but the last component of sound (i.e., being heard) is absent
and therefore it makes no sound
because sound is
the mental perception of the vibration of the air (or other medium).
