Unless otherwise indicated by context, the following
terms and phrases shall mean:
A device which draws in air or gas, compresses it and delivers
it at a higher pressure.
The all-encompassing noise associated with a given environment,
being usually a composite of sounds from many sources near and far.
The sound-pressure level in decibels as measured on a sound-level
meter using the A-weighing network and designated as "db(A)."
Construction performed by persons, paid or unpaid, other
than the homeowner; construction performed by any person or entity
who receives any payment for their services.
[Added 1-11-2011]
Any activity necessary or incidental to the erection, demolition,

property, including but not limited to related activities such as
land clearing, grading, earthmoving, excavating, blasting, filling
and landscaping.
Any location, including land and water, where construction
takes place.
Any sound that is not an impulsive sound.
A unit for measuring the volume of sound, equal to the logarithm
to the base 10 of the ratio of the pressure of the sound; the quantities
concerned are proportional to power (American National Standards Institute
terminology).
Any machine, mechanism or equipment which is intended to
or which actually produces sound or vibrations.
A sound wave whose instantaneous sound pressure varies essentially
as a simple sinusoidal function of time (American National Standards
Institute terminology).
The operation or parking of an authorized emergency vehicle
when such vehicle is engaged in transporting a sick or injured person,
responding to or working or assisting at the scene of an accident,
disaster, police call, alarm of fire or any emergency.
A system which removes and transports air or gas from a device.
A function periodic in time which is the reciprocal of the
period.
A sound of short duration, usually less than one second,
and of high intensity, with an abrupt onset and rapid decay (American
National Standards Institute terminology). (Examples include an explosion
or discharge of a firearm.)
The A-weighted sound level measured with slow response that
is exceeded 10% of the time in any one-hour interval. The measurement
time interval need not be one hour, provided that the measurement
results are representative of a one-hour interval.
The A-weighted sound level measured with slow response that
is exceeded 90% of the time in any one-hour interval. The measurement
time interval need not be one hour, provided that the measurement
results are representative of a one-hour interval.
The weight of the vehicle unladen, plus the weight of the
maximum load to be carried by such vehicle during the registration
period, or the maximum gross weight for which the vehicle is registered,
whichever is greater.
Every vehicle operated or driven upon a public highway, which
is propelled by any power other than muscular power.
A device for abating the sound of escaping gases of an internal
combustion engine or other sound source.
An area adjacent to a site, including but not limited to
any authorized school, church, senior citizen center, day-care center
or hospital which requires specific noise limitations.
Any powered construction device that is designed to be used
or is actually used to cut or trench pavement subbase, macadam, gravel,
concrete or hard ground.
Includes the singular and plural and also any person. firm,
corporation, political subdivision, government agency, association,
club, partnership, society or any other form of association or organization,
or any legal entity whatsoever.
Any highway, road, street, avenue, public place, public driveway

Any vehicle which is propelled by any power other than muscular
power that is designed for or capable of cross-country travel, such
as a motorcycle, trail bike or minibike. A recreational vehicle is
also classed as a motor vehicle when such recreational vehicle is
operated or driven upon a public highway. Lawn mowers, powered garden
vehicles and other similar utilitarian domestic vehicles are specifically
excepted therefrom.
Any motor vehicle designed to compact and transport refuse.
Any self-propelled vehicle designed for travel on snow or
ice.
An oscillation in pressure, stress, particle displacement
or other physical parameter in a medium with internal forces (American
National Standards Institute terminology).
The weighted pressure level, measured by the use of a metering
characteristic and the weighing A, B and C (American National Standards
Institute terminology).
An instrument, including a microphone, an amplifier, an output
meter and frequency-weighing networks for the measurement of sound
levels (American National Standards Institute terminology).
Any device that is designed to be used or is actually used
for the production or reproduction of sound, including but not limited
to any musical instrument, radio, television, tape recorder, phonograph
or any other sound-amplifying equipment.
Any activity or device that produces sound.
