I live near both those things and can put up with the intermittent noise. Leafblowers are an invention of Satan and must be destroyed, preferably along with their owners and operators. They are the epitome of laziness.
It was an unincorporated location, and the county sheriff couldn't be bothered.
It also turned out that the little local street was a shortcut. "Intermittent" turned out to be a... weak description of the traffic situation.
I nonetheless grew at least somewhat accustomed to the passing noise. The non-stop, however...
Oh, and those same neighbors didn't have Harleys, but they did seem to be of the opinion that every vehicle had to have glass packs or something similar. And that they had to be "tuned up", with sometimes an hour or more of engine revving, seemingly weekly.
By comparison, I can hear a leaf blower. But as a fairly constant drone, and one that does not, at low frequency, pass right through the house, I find it comparatively easy to take.
A Silent leafblower sounds like a potential invention.
