in thread What's that noise?

Speaking purely scientifically, YES.

Regardless of the presence of any one (or thing), sound waves are produced (see below for logic); the ripping of plant cells, cracking of the timber, the rush of wind and russeling of leaves as the tree falls, the impact.

Sound is defined as waves within a specific frequency (I refer you to here for the denotative meaning). So as long as a frequency wave (or waves) within the appropriate human range are produced, a *sound* is made. Just my 2 cents.
