Points 4 and 8 also combine here. The new "green" garbage trucks the vendor in my city has begun using are so INCREDIBLY loud. Even just the engine noise from them. The PTO and gearbox noise is just atrocious, tons of turbo noise, tons of just weird mid frequency resonant whining. They're some of the loudest trucks i've ever heard, and are basically as loud as monster trucks or straight pipe hot rods. I'm completely not exaggerating that they're multiple harley davidson loud, and at a more annoying frequency.
I've gotten like stabbing ear pain from being near one of these accelerating hard.
