Seems like one compromise would be that they can only be used during a few-hour period every other week or so. So you'd only get the noise in a predictable window.
Those leaf blowers put more garbage into the air than a car or pickup truck. They're that bad.
I've spent a lot of time in the countryside where there is a motorway in the distance, and the general low rumble road noise seems to be mostly the tires etc. But then sometimes a loud motorbike revs and that really carries and intrudes.
