The Town Council finds that inadequately controlled
or excessive noise negatively affects the public health, safety, convenience,
general welfare, and quality of life of persons within the Town of
New Canaan, and that the people have a right to, and should be ensured
of, an environment free from excessive and intrusive noise. This ordinance
is enacted to preserve, protect and promote the public health, safety,
convenience, general welfare, peace, quality of life, and property
values for the citizens of New Canaan, and to facilitate the enjoyment
of the natural attractions and tranquility of the Town, through the
reduction, control and prevention of excessive noise and vibration.
The words and phrases used in or implicated
by this ordinance, unless defined below, shall be construed with reference
to the state statutes on noise pollution control (Connecticut General

(Regulations of Connecticut State Agencies § 22a-69-1 et
seq.), as the same may be amended from time to time. In addition,

The Town Council finds that certain noise-producing

the Town of New Canaan, and therefore any violation of the following

within five minutes for continuous airborne sound or for impulsive
sound after it has been activated.
B. Motorized equipment or machinery with engines powered
by electricity, gasoline or other fuel products, such as snow blowers,
snow throwers, leaf blowers, leaf vacuums, lawn mowers, tractors,
trimmers, chainsaws, wood chippers, log splitters, and generators,
excluding motor vehicles, shall be operated at all times with a muffler
in working order to abate the exhaust, combustion and explosive noises
therefrom. In addition, with the exception of snow blowers and snow
throwers, such equipment may not be operated in the following time
periods such that the noise therefrom exceeds 45 dBA measured at the
receptor's property line:
