Based on my quick analysis of the on-page examples, the only pattern is that loudspeaker trucks are funny (about half of the 18 examples), and 0 of them actually describe a "frozen moment of awkwardness [...] highlighted by the passing of a loudspeaker truck".
I agree that this doesn't look like much of a trope right now.
The Ranma ½ example at the top of the section may be a proper example, except it's a ZCE.
Having looked at it... Jesus. From the description, I think there is a trope here (something dramatic/cringeworthy happens, the characters stand in shocked silence, a loudspeaker truck drives past to break the mood in a funny way), but 95% or so of the examples are literally "loudspeaker trucks* exist." EDIT: Even the image is just a photo of a loudspeaker truck, rather than something showing the trope.
I think this should go on the TRS list.
(*Or older variations, like wandering salesmen crying their wares)

Given the rarity, wouldn't a more general trope of "awkward / intense moment is interrupted by something random and unrelated" be better? That probably already exists.
Very good point.
I suspect the reason loudspeaker trucks (or the older form, street salesmen/rag-and-bone collectors) are commonly used is because they're loud, making for a funnier moment of incongruity than if it was something more subtle.
Would just merging it into Moment Killer work?
Scientia et Libertas | Per Aspera ad Astra NovaWhat is being talked of is narrower than that. A rename to Awkward Scene Loud Interruption might work.
Stories don't tell us monsters exist; we knew that already. They show us that monsters can be trademarked and milked for years.That'd be a good trope to contrast Hell Is That Noise.

Loudspeaker Truck seems like a child of both worlds to me, both being Too Rare to Trope and People Sit on Chairs. The definition is essentially "loudspeaker trucks are an inconvience/disturb the peace" and that's it. The description does go into tiny detail about how the trope would be used in a real-life Japanese setting, such as for the purpose of bamboo for drying laundry or political campaigns, but all that really does is reflect on the rarity of it. It's such a starved trope that I haven't seen it mentioned anywhere outside of the archived discussion—which actually has/had a comment suggesting it be a useful note instead—and here, but even then it's a passing mention for a completely unrelated Image Pickin' thread.
The oldest version of the page I could find dates back to May 2006, with the trope itself existing since February of that year at the latest, meaning this trope was created before YKTTW was a thing. That's...not very promising. Analogy-wise, the first thing that popped into my mind was that this trope is like a partially-unwrapped butter stick at the back of the fridge that's too mysterious for anyone to want to go near or have even heard about.
