Hello Greg,
I must honestly say this is in the realm of speculation, as I believe there has been no solid research on the possibility of developing TMJ as a consequence of acoustic trauma (and hence I have no references). But think of it; an acoustic trauma gives you some kind of "nerve insult" in an area where nerves are closely intertwined with each other.

As you can see in the above image, all nerves in the facial area come together in the trigeminal nucleus. It wouldn't be far-fetched to think that an insult to one of the nerves in this crowded area can have side effects in other places near this area. These nerves control muscles in the area; muscles near your jaw, muscles near the eustachian tubes and the tympanic membrane. If these nerves are going to send unexpected signalling due to an insult somewhere in the network of nerves, the muscles are potentially going to behave erratically. This could result in muscle twitching and hence; jaw pain, ear popping, feelings of fullness, sensation of pulled or stiff muscles, issues opening the mouth (also muscles). In short; TMJ-like symptoms. That's my personal theory.
Also look into the work of Susan Shore, she is on a similar path. Not specifically regarding TMJ, but somatic tinnitus.
