Article XV Noise Controls
[Added 9-30-2010 by Ord. No. 2010-04]
This article shall apply to the control of all sound originating within the limits of Caln Township.
As used in this article, the following terms shall have the meanings indicated herein:
Any site preparation, assembly, erection, repair, alteration or similar action, including demolition of buildings or structures.
CONTIGUOUS LAND USE
Any land use bordering or abutting, whether divided by real property boundary or by real property boundary and public street.
CONTINUOUS SOUND
Any sound which is static, fluctuating or intermittent with a recurrence greater than one time in any fifteen-second interval.
DECIBEL (DB)
A numerical expression of the relative loudness of a sound.
Any dismantling, destruction, or removal of buildings, structures or roadways.
Any occurrence or set of circumstances involving actual or imminent physical trauma or property damage which demands immediate action.
IMPULSIVE SOUND
Sound of short duration with an abrupt onset and rapid decay and an occurrence of not more than one time in any fifteen-second interval.
The actual real use of land and buildings thereon situated regardless of the zoning or other classification attributed to such land and buildings.
A vehicle which is self-propelled except for one which is propelled solely by human power or by electric power obtained from overhead trolley wires.
Any sound which annoys or disturbs humans or which causes or tends to cause an adverse psychological or physiological effect on humans.
PLAINLY AUDIBLE SOUND
Any sound that can be detected by a person using his or her unaided hearing facilities.
PURE TONE
Any sound which can be distinctly heard as a single pitch or a set of single pitches. For the purposes of this article, a pure tone shall exist if the 1/3 octave band sound pressure level in the band with the tone exceeds the arithmetric average of the sound pressure levels of the two contiguous 1/3 octave bands by five dB for center frequencies of 500 Hz and above, by eight dB for center frequencies between 160 Hz and 400 Hz and by 15 dB for center frequencies less than or equal to 125 Hz.
RECEIVING LAND USE
The land use which is a contiguous use to the noise source.
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 characteristic of such sound, including duration, intensity and frequency.
SOUND DISSIPATIVE DEVICE
A noise control device intended to abate or lessen the noise made by vehicles, equipment or machinery.
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 SI.4-1971, or the latest approved revision thereof). If the frequency weighting employed is not indicated, the A-weighting shall apply.
An instrument which includes a microphone, amplifier, RMS detector, integrator or time averager, output meter and weighting networks used to measure sound pressure levels. The sound level meter used for testing purposes in accordance with this article shall meet the current American National Standard Institute specifications.
The Caln Township Zoning Officer shall have the power to administer the terms of this article, to investigate complaints and prosecute violations of this article in accordance with Article XIII of this Chapter. When enforcing the terms of this article, the Zoning Officer may retain consultants and engineers with experience in measuring sound levels with the use of sound level meters.
Specific prohibited acts. The following actions are specifically prohibited regardless of the sound level which is emitted, unless otherwise exempted in this article:
No person shall operate, play or permit the operation or playing of any radio, television, phonograph, drum, musical instrument, cassette player, sound amplifier or similar device which produces, reproduces or amplifies sound between the hours of 10:00 p.m. of one day and 7:00 a.m. of the following day in such a manner as to be plainly audible across a property line.
No person shall operate or permit the outdoor operation of any tools, equipment or machinery used for construction operations, drilling or demolition, or in the sweeping of parking lots between the hours of 10:00 p.m. of one day and 7:00 a.m. of the following day in such a manner as to be plainly audible across a property line.
No person shall operate or permit the outdoor operation of any powered tool, equipment or machinery (including but not limited to electrically powered saw, drill, sander, grinder, lawn or garden tool) between the hours of 10:00 p.m. of one day and 7:00 a.m. of the following day in such a manner as to be plainly audible across a property line.
No person shall load or unload trucks or other motor vehicles or open, close or otherwise handle boxes, crates, containers, building materials, garbage cans or other objects between the hours of 10:00 p.m. of one day and 7:00 a.m. of the following day in such a manner as to be plainly audible across a property line.
No person shall own, possess, harbor or control any animal or bird which howls, barks, meows, squawks or makes other sounds continuously and/or incessantly for a period of 10 minutes or makes such noise intermittently for 1/2 hour or more to the disturbance of any person at any time of the day or night, regardless of whether the animal or bird is situated in or upon private property; provided, however, that at the time the animal or bird is making such noise, no person is trespassing or threatening to trespass upon private property in or upon which the animal or bird is situated or for any other cause which teased or provoked the animal or bird.
No person shall remove or render inoperative a sound dissipative device from motor vehicles, equipment or machinery, other than for purposes of maintenance, repair or replacement when such motor vehicle, equipment or machinery is not in use; intentionally move or render inaccurate or inoperative any sound-monitoring instrument or other device positioned by or for the Township or other governmental entity or agent thereof; or use any motor vehicle, equipment or machinery which has had a sound-dissipative device or any part thereof removed or rendered inoperative.
No person shall repair, rebuild or test or otherwise work on any motorcycle, motor vehicle, motorboat or aircraft outdoors between the hours of 10:00 p.m. of one day and 7:00 a.m. of the following day in such a manner as to be plainly audible across a property line.
Except for emergencies, no person shall intentionally sound or permit the sounding outdoors of any fire, burglar or civil defense alarm or any similar stationary emergency signaling device intended for public notification.
General performance standards/noise levels.
In those cases not specifically controlled by § 155-185A above, no person shall operate or cause to be operated on private or public property any source of continuous sound (any sound which is static, fluctuating or intermittent with a recurrence greater than one time in any fifteen-second interval) in such a manner as to create a sound level which exceeds the limits set forth for the receiving land use category in the following table when measured at or within the property boundary of the receiving land use. All measurements shall be made with a sound level meter which is in conformance with American Standards Association specifications.
Continuous sound levels by receiving land use.
Receiving Land Use Category
Sound Level Limit
(dBA)
Residential, public space, open space, agricultural or institutional
10:00 p.m. to 7:00 a.m. plus Sundays and legal holidays
Commercial or business
At all times
Correction for character of sound. For any source of sound which emits a pure tone, the maximum sound-level limits set forth in the above table shall be reduced by five dBA. For any source of sound which emits an impulsive sound (a sound of short duration, with an abrupt onset and rapid delay and an occurrence of not more than one time in any fifteen-second interval), the excursions of sound pressure level shall not exceed 20 dBA over the ambient sound pressure level, regardless of the time of day or night or receiving land use, using the "fast" meter characteristic of a Type II meter, meeting ANSI Specification SI.4-1971.
The following noises are exempted from the provisions set forth in § 155-185 of this article:
Blasting, only if performed in accordance with a permit issued by the Pennsylvania Department of Environmental Protection. Such blasting may occur only between the hours of 7:00 a.m. and 5:00 p.m., Monday through Friday, unless specifically authorized at different times by the DEP permit.
