Brookline Ma and Newton Ma already have decibel levels maximums on such equipment.
Cambridge might too and probably others.
There are threads on it.
Brookline straight up banned gas leaf blower use for good portions of the year. Only two at a time on lots of 7,500 sq. Ft. or less, landscape companies have to be permitted by the town, blah blah. Brookline and Newton lead the way when it comes to placating Karens and virtue signaling.
