its acoustic energy prevented from dissipating by------> is an absolute modifier

an absolute modifer is formed by either deleting the auxliliary verb or the 'be' verb.

this choice would have been a run on sentence if the modifying part( by this i mean the whole its clause) read something like;


its acoustic energy (was) prevented from dissipating by..........

all correct.
as far as i can tell, though, all absolute phrases are created by removing some form of "to be" (is, are, was, were, etc.)
your phrasing -- "auxiliary verb OR 'to be' form" -- suggests that there are some other "auxiliary verbs" that can also be removed to create absolute phrases.
if that's what you were saying, what are those other auxiliary verbs? i can't think of any such verbs myself.

thanks

I do not think this would have been a run on sentence at all, both the sentences will have main verb in the case described above.( i.e if the modifier was supplied a 'be' verb).
What would have resulted, in fact, would have a comma splice.

Hmm... a comma splice is an error in English. It means two independent clauses joined by a comma. Most grammar writers consider a comma splice a form of run-on sentence, though some consider it a distinct sort of error. It's a distinction without a difference as far as the GMAT is concerned.

Let's take a look at the sentence Roshan characterizes as run-on:

Sound can travel through water for enormous distances, its acoustic energy is prevented from dissipating....

That's wrong. Sound can travel... and its energy is prevented ... are both independent clauses. I'd characterize it as a run-on, but you certainly don't have to.
