Noise Differences Between Two and Four Cycle Gas Powered Leaf
Blowers
Councilmember Ashbaugh requested that, if possible, staff provide a demonstration and
comparison of two cycle and four cycle gas leaf blowers tonight for the Council's
consideration of agenda item B 2. While it was not possible for staff to put the
demonstration together, staff is able to provide information relevant to Councilmember
Ashbaugh's request.
The City provides a handout on the proper use of leaf blowers based on existing noise
regulations regarding blowers and best practices. This handout is attached (see page 2).
The City's noise regulations and the content of the handout apply equally to two and four
cycle engines. Either the two or the four stroke engines can exceed or comply with the
City's existing noise limits for leaf blowers. Thus prohibiting two cycle gas engines in
the City does not eliminate the potential for four cycle engines to exceed the noise limits.
It is the proper operation and maintenance of the equipment in accordance with best
practices that will insure compliance with the noise standards.

lf you see someone operating a blower illegally (outside
of the hours when they are allowed), let him or her know.
lf you are unable to speak to the blower operator directly,
you can call the Police Department at 781-731-7. lt
is not an emergency, but an officer will respond as soon
as possible.
Please rememberthat, as with other noise violations, a
police offlcer cannot issue a citation if he or she does
not actually hear the blower personally. Do not be
disappointed if a citation is not issued, however.l'he
officer will inform the suspected blower user of the law,
which should reduce future violations.
