The following words, terms and phrases, when used
in this chapter, shall have the meanings ascribed to them in this
section, except where the context clearly indicates a different meaning:
AMBIENT NOISE LEVEL
The all-encompassing background noise associated with a given
environment without the sound contribution of the specific source
in question.
DECIBEL
A standard unit for measuring the sound-pressure level. It
is equal to 20 times the logarithm to the base 10 of the ratio of
the pressure of the sound measured to a reference pressure which is
20 micropascals; denoted as "dB."
EMERGENCY
Any occurrence or set of circumstances involving actual or
imminent physical trauma or property damage which demands immediate
action.
EMERGENCY VEHICLE
A motor vehicle used in response to public calamity or to
protect persons or property from imminent danger.
MOTOR VEHICLE
The same as defined in the state Motor Vehicle Code or any 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, mopeds, amphibious craft on land, dune buggies or racing
vehicles.
NOISE
Any sound which is unwanted or which causes or tends to cause
any adverse physiological or psychological effect on human beings.
NOISE DISTURBANCE
Any sound which:
(1)
Endangers or injures the safety or health of
humans or animals.
(2)
Annoys or disturbs a reasonable person of normal
sensibilities.
(3)
Jeopardizes the value of property and erodes
the integrity of the environment.
(4)
Is in excess of the allowable noise levels established in §
100-5.
NOISE, PLAINLY AUDIBLE
Any 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 VEHICLES
Any 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, rockets, which can be propelled
by mechanical means.
PROPERTY BOUNDARY
An imaginary line which separates the real property owned
or possessed by one person or governmental entity from that owned
or possessed by another person or government entity.
PURE TONE
Any sound which can be distinctly heard as a single pitch
or set of single pitches. For the purpose of this chapter, a "pure
tone" shall exist if the 1/3 octave band sound-pressure level and
the band with the tone exceeds the arithmetic average of the sound-pressure
level of the two contiguous 1/3 octave bands by 15 dB for bands with
center frequencies less than 160 Hz, eight dB for bands with center
frequencies of 160 Hz to 400 Hz and by five dB for bands with center
frequencies greater than 400 Hz.
SOUND
A 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 which propagates at finite speed
to distant points.
WEEKDAY
Any Monday, Tuesday, Wednesday, Thursday or Friday which
is not legally designated a holiday.
