We have this in New York City to monitor the flow of traffic on quiet residential streets. If the flow rate is OK, it's nice and quiet. If the flow rate gets too low (or a traffic light turns red) then a chorus of very angry car horns erupts, and you are jolted out of your train of thought, wishing you had the guts / tolerance for prison time to run outside and smash every single one of the cars with a crowbar.

I think a recording of this is actually built into Pagerduty to use as a sound when you're getting paged. I went with the "golf ball hit into a flock of geese" one, though. Every time that goes off my first thought is "OH GOD I'M DYING HELP" but then I look and it's just GCP down again. Ironically therapeutic.

There is an implementation and a paper called peep, the network auralizer. I've been thinking of building something like this in rust or go as a learning project, but audio streaming and mixing is harder than I thought. If someone has good libraries or tutorials there, I'd be grateful.
