EMERGENCY VEHICLEA motor vehicle used in response to a public calamity or to protect persons or property from imminent danger.
EMERGENCY WORKWork made necessary to restore property to a safe condition following a public calamity, work to restore public utilities or work required to protect persons or property from an imminent exposure to danger.
HABITUAL HOWLING, BARKING, MEOWING, SQUAWKING OR OTHER NOISEMAKINGContinuous barking, crying or other noisemaking, without pauses of one minute or longer, for a period of more than 20 minutes between the hours of 6:00 a.m. and 10:00 p.m., or for a period of more than 10 minutes between the hours of 10:00 p.m. and 6:00 a.m., on at least two occasions over a three-month period.
MOTOR VEHICLEAny vehicles which are propelled or drawn by mechanical equipment, such as but not limited to passenger cars, trucks, truck trailers, semitrailers, campers, motorcycles, minibikes, go-carts, snowmobiles, amphibious craft on land, dune buggies or racing vehicles.
MUFFLERAny apparatus consisting of baffles, chambers or acoustical absorbing materials whose primary purpose is to transmit liquids or gases while causing a reduction in sound emission at one end.
NOISE DISTURBANCEAny sound which annoys, disturbs or perturbs reasonable persons with normal sensitivities, or any sound which injures or endangers the comfort, repose, health, hearing, peace or safety of other persons.
NOISE SOURCEAny device, fixed or movable, which is located or used on geographically defined real property other than a public right-of-way.
PERSONAny individual, association, partnership or corporation and includes any officer, employee, department, agency or instrumentality of the United States, a state or any political subdivision of that state.
PLAINLY AUDIBLE NOISEAny noise for which the information content of that noise is unambiguously communicated to the listener, such as but not limited to understandable spoken speech or comprehensible musical rhythms.
POWERED MODEL VEHICLESAny powered vehicles, either airborne, waterborne or landborne, which are designed not to carry persons or property, such as but not limited to model airplanes, boats, cars or rockets, and which can be propelled by mechanical means.
PROPERTY BOUNDARYAn imaginary line at the ground surface, which line separates the real property owned by one person from that owned by another person and its vertical extension.
SOUNDA temporal and spatial oscillation in pressure, or other physical quantity, in a medium with internal forces that causes compression and rarefaction of that medium and that propagates at finite speed to distant points.
STATIONARY EMERGENCY SIGNALING DEVICESAny device, excluding those attached to motor vehicles, used to alert persons engaged in emergency operations. These include, but are not limited to, firefighters, first-aid squad members and law enforcement officers, whether paid or volunteer.
STEADY NOISEA sound-pressure level which remains essentially constant during the period of observation, i.e., the fluctuations are too small to meet the criterion for fluctuating noise.
WEEKDAYAny Monday, Tuesday, Wednesday, Thursday or Friday which is not a legal holiday.
