I can't think of an exception to this in any city I've been in, honestly. Which cities have lots of clubs and bars with loud speakers out the front? Is that common in the states?
Half the problems with America seems to be lack of regulation and the assumption that it can't be changed :)
Like our party was able to carry a bazooka around openly in one state :)
A perfectly practical solution would be for the town to designate "outdoor power equipment times" such as "Saturday, 10-4" or "any day, 10-12, 3-4" or similar.
Electric is helping but even then there's noise created from just the action of the device, and you also reach a paradox where as things get quieter the remaining noise sources become more annoying.
In terms of decibels cars are indeed louder. But not all noise is created equal.
I have noise-cancelling headphones - they do a great job removing white noise(so traffic, among others), but aren't too effective against sounds with a more focused spectrum like people yelling in the middle of the night, bottles being broken or trash being collected in the middle of the night.
Paris is very densely populated - I'm surprised anyone attempts to drive there, because at these densities and distance between buildings it must be horrible.
My point is: it's not that clear cut. Removing cars is what makes places like Paris bearable, but the problem lies in the sheer population density that a truly walkable city over a certain scale requires.
I moved to a city that has 2/3 the population density of my previous location and even though it's just swamped with traffic, it's actually quieter on average.
I feel like population density is completely left out of the conversation. From my experience there's a middle ground between car-oriented suburbs and human pile-ups like Paris(or other cities approaching this density) which is rarely explored.
There is no magic, just legal regulation and it just works. Switzerland and Japan are good examples.
The Dutch city of Delft in particular is just intentionally designed to care about noise. Both design and regulations. Turns out that when you simply prioritize reducing noise, it's actually doable. And it's still a city, albeit a modest-sized small city, not a major regional hub or a global-level metropolis. But the lessons can be applied anywhere.
