As used in this chapter, the following terms shall
have the meanings indicated:
AMBIENT NOISE
The all-encompassing noise associated with a given environment,
usually being a composite of sounds from many sources near and far.
A-WEIGHTED SOUND LEVEL
The sound-pressure level in decibels as measured on a sound-level
meter using the A-weighting network. The level so read is designated
"dB(A)."
CONSTRUCTION OPERATION
The erection, repair, renovation, demolition or removal of
any building or structure and the excavation, filling, grading and
regulation of lots in connection therewith.
DECIBEL (dB)
A unit for measuring the sound-pressure level, equal to 20
times the logarithm to the base 10 of the ratio of the pressure of
the sound measured to the reference pressure, which is 20 micropascals
[20 micronewtons per square meter].
EMERGENCY
Any occurrence or set of circumstances involving actual or
imminent physical trauma or property damage.
EMERGENCY WORK
Any work performed for the purpose of preventing or alleviating
the physical trauma or property damage threatened or caused by an
emergency.
IMPULSIVE SOUND
Sound of short duration, usually less than one second, with
an abrupt onset and rapid decay. Examples of "impulsive sound" include
explosions, drop-forge impact and the discharge of firearms.
NOISE
Any sound which annoys or disturbs humans or which causes
or tends to cause an adverse psychological or physiological effect
on humans.
NOISE DISTURBANCE
Any sound which endangers or injures the safety or health of humans or animals or annoys or disturbs a reasonable person of normal sensitivities or endangers or injures personal or real property or is in excess of the sound levels by zoning districts established in §
169-5.
PERSON
Any individual, association, partnership or corporation,
and includes any officer, employee, department, agency or instrumentality
of a state or any political subdivision of a state. Whenever used
in any clause prescribing and imposing a penalty, "person" incudes
the individual members, partners, officers and managers, or any of
them, of partnerships and associations and as to corporations, the
officers and managers thereof or any of them.
POWERED MODEL VEHICLE
Any self-propelled airborne, waterborne or landborne plane,
vessel or vehicle which is not designed to carry persons, including
but not limited to any model airplane, boat, car or rocket.
PROPERTY LINE (BOUNDARY)
An imaginary line drawn through the point of contact of adjoining
lands, apartments, condominiums, townhouses and duplexes owned, rented
or leased by different persons, a demarcation or a line of separation
of properties and also, for any two or more buildings sharing common
grounds, the line drawn midway between any two said buildings. All
areas devoted to public right-of-way shall be deemed to be across
the "property line." For the purpose of this regulation, the "property
line" includes all points on a plane formed by projecting the "property
line" in a manner deemed appropriate by the enforcing police officer.
PUBLIC RIGHT-OF-WAY
Any street, avenue, boulevard, highway, sidewalk, alley or
similar place which is owned or controlled by a governmental entity.
PUBLIC SPACE
Any real property or structures thereon which are owned or
controlled by a governmental entity.
PURE TONE
Any sound which can be heard as a single pitch or a set of
single pitches. For the purpose of this chapter, a "pure tone" shall
exist if the 1/3 octave band sound-pressure level in the band with
the tone exceeds the arithmetic average of the sound-pressure levels
of the two contiguous octave bands by five dB for center frequencies
of 500 hertz and above and by eight dB for center frequencies between
160 and 400 hertz and by 15 dB for center frequencies less than or
equal to 125 hertz.
REAL PROPERTY
All land, whether publicly or privately owned, whether improved
or not improved, with or without structures, exclusive of any areas
devoted to public right-of-way.
SOUND
An oscillation in pressure, particle displacement, particle
velocity or other physical parameter, in a medium with internal forces
that causes compression and rarefaction of that medium. The description
of "sound" may include any characteristics of such sound, including
duration, intensity and frequency.
SOUND LEVEL
The weighted sound-pressure level obtained by the use of
a sound-level meter and frequency-weighting network, such as A, B
or C, as specified in American National Standards Institute specifications
for sound-level meters (ANSI S1.4-1974 or the latest revision thereof).
If the frequency weighting employed is not indicated, the A-weighting
shall apply.
SOUND-LEVEL METER
An instrument which includes a microphone, amplifier, RMS
detector, integrator or time averager, output meter and any applicable
weighting network used to measure sound-pressure levels which meets
or exceeds the requirement for a Type I or Type II sound-level meter
as specified in ANSI Specification S1.4-1974. The manufacturer's published
indication of compliance with such specifications shall be prima facie
evidence of such compliance.
ZONING DISTRICTS
The land use districts established by the Zoning Ordinance
of the Township of Nether Providence and all subsequent amendments.
