Interesting. I'm definitely looking forward to electric buses and trucks though. Standing on the sidewalk when a bus accelerates next to you can be offensively loud.
A city in Germany (Osnabrueck) has switched all their buses to electric. They are much more silent, for sure.
I also don't feel like electric cars are more loud, at least at moderate speeds. I always had the impression that they're a lot more silent inside cities. Maybe on a highway that would be different, I can't say.
The biggest offenders of background noise are obviously trucks though.
Not where I lived, when I lived in a city. The worst offenders by far were motorcycles and cars which had aftermarket exhausts designed to be noisy. Much of the noise on roads is intentional.
