I'm amazed that something like a passenger car on the street is even allowed to produce 126db regardless of how it does it. I mean I don't really care if it's coming from an ICE, a speaker system, or an air horn, people should have a really good reason to generate that much sound pollution and I can't think of any short of needing it to save a life. P.S. In the EU at least the legally mandated AVAS is actually a carefully studied sound with a mix of specific frequencies aimed at being clearly distinguishable regardless of age (can be heard by old and young eardrums), has specific attenuation parameters (doesn't travel too far but also doesn't dissipate too close), can be relatively easily pinpointed as a source, works up to a relatively low speed before rolling noises become prevalent, and doesn't go above 75dB(A) (just enough to be audible in city landscapes). It's pretty much the Star Trek Enterprise engine futuristic sound which you'd be hard pressed to find disturbing in any way.
