It is the purpose and scope of this part to provide regulations
defining the maximum sound levels that vehicles, appliances and equipment
shall be allowed to produce at specific distances from these devices
and also to provide for the prohibition of specific sources of noises.
These regulations and prohibitions are intended to protect the physical,
mental and social well-being of the residents of the Borough of Sharpsburg.
The following devices are exempt from the provisions of these
regulations:
1. Aircraft (except model aircraft).
2. Police, fire, ambulance and other governmental emergency vehicles.
3. Back-up alarm devices on vehicles and other equipment when installed
and operated in accordance with the Society of Automotive Engineers'
recommended practice J 994, "Criteria for Back-up Alarm Devices."
4. Governmental warning devices (i.e., civil defense or fire siren).
All acoustical terminology shall be that contained in ANSI S1.1,
"Acoustical Terminology."
ANSI
American National Standards Institute or its successor.
APPLIANCE
Any device or combination of devices used or capable of being
used as a means of accomplishing a desired end, such as a window air-conditioning
unit.
BACKGROUND SOUND LEVEL
The measured sound level in the area without the sound contribution
of the specific source in question.
DAY
The twenty-four-hour period starting at local midnight.
DECIBEL (dB)
A unit of sound level which is a division of logarithmic
scale used to express the ratio of the sound intensity of the source
to the intensity or an arbitrarily chosen reference intensity. The
ratio is expressed on the decibel scale by multiplying its base 10
logarithm by 10.
EQUIPMENT
Any devices or combination of devices to accomplish a desired
end, such as a chain saw, bulldozer, etc.
EXCESSIVE NOISE
Excessive noise is that sound which is injurious or which
unreasonably interferes with the comfortable enjoyment of life and
property. Measured noise levels in excess of limits established in
these regulations or those specified in valid permits are declared
to be excessive noise, annoying to a person of ordinary sensibilities.
EXCESSIVE VIBRATION
The presence of a vibration or vibrations:
1.
Of such intensity, duration, frequency or character to annoy,
disturb or cause or tend to cause adverse psychological or physiological
effects on persons, or damage or tend to damage personal or real property.
2.
In excess of standards promulgated by the Board of Health.
FLUCTUATING NOISE
A fluctuation noise whose sound level varies significantly
with time.
IMPULSIVE NOISE
Impulsive noise is characterized by brief excursions of sound
level. The duration of a single impulse is usually less than one second.
INTERMITTENT NOISE
An intermittent noise is a noise whose sound level exceeds
the ambient noise levels at least twice during the period of observation,
which is one minute or more. The period of time during which the level
of the noise remains at an essentially constant value different from
that of the ambient is on the order of one second or more.
NOISE
The presence of a sound or sounds of such intensity, duration,
frequency or character which would cause a person of ordinary or reasonable
sensibilities to be annoyed, disturbed, or cause or tend to cause
adverse psychological and physiological effects on such persons.
ORDINANCE ENFORCEMENT OFFICER
Any person appointed by the Borough of Sharpsburg with responsibility
to enforce Borough ordinances; or any sworn member of the Borough
Police Department.
PERIOD OF OBSERVATION
The period of observation is the time interval during which
acoustical data is obtained. The period of observation is determined
by the characteristics of the noise being measured and the instrumentation
being used. The period of observation must be at least as long as
the response time of the instrumentation. The greater the variance
in individual sound level, the longer must be the observation time
for a given expected accuracy of measurement.
PERSON
Any individual, natural person, syndicate, association, partnership,
firm, corporation, institution, agency, authority, department, bureau
or instrumentality of federal, state or local government or other
entity recognized by law as a subject of rights and duties.
PROPERTY
All land whether improved or not improved within or without
structures.
PROPERTY BOUNDARY
The surveyed line at ground surface which separates the facility
owned, rented or leased by one or more persons from any other such
facilities.
SOUND LEVEL (NOISE LEVEL)
Airborne sound levels are expressed in dB and obtained by
the use of specific frequency-dependent weighting networks, as specified
in the referenced standards. The specific weighting network used must
be indicated by the proper notation. If the A-weighting is employed,
the sound level is identified as dB(A).
SOUND LEVEL METER
An instrument or combination of instruments which meets or
exceeds the requirements for an ANSI Type S1A or Type S2A sound level
meter.
SOUND PRESSURE
The instantaneous differences between the actual pressure
and the average or barometric pressure at a given point in space,
as produced by sound energy.
SOURCE
Any entities of sound and/or vibration.
STEADY NOISE
A noise whose level remains essentially constant (i.e., fluctuations
are less than five dB) during the period of observation is a steady
noise.
VEHICLE
Any device or combination of devices used for or capable
of being used for transporting persons or property. Vehicles include,
but are not limited to, the following: automobiles, trucks, buses,
motorcycles, motorized bicycles, snowmobiles, scooters, all-terrain
vehicles, go-carts, racers and like devices, farm machinery, industrial
machinery, highway graders, trailers, graders and semitrailers.
VIBRATION
An oscillatory motion of solid bodies of deterministic or
random nature described by displacement, velocity or acceleration
with respect to a given reference point.
The Borough of Sharpsburg shall:
1. Have available in convenient form as in a unit the provisions of
this part and the recommended practices, rules, regulations and standards
which have been adopted. A copy of the information sources shall be
kept on file in the Borough of Sharpsburg offices.
2. Prepare and maintain records of all orders issued by the noise enforcement
officers and the Appeals Board.
3. By the Mayor and Council officials, issue all standards, permits,
certificates, notices or other matters required under the provisions
of this part, and notify all persons concerned of any decisions rendered,
and provide such persons with an opportunity to be heard as herein
set forth.
4. Establish an advisory committee to investigate and make recommendations
from time to time to Council with respect to needed additions or revisions
of this part.
Maximum permissible noise levels above background sound level,
unless otherwise specifically designated herein, measured at point-of-complaint
origination or boundary:

Any person, firm or corporation who shall violate any provision
of this part shall, upon conviction thereof, be sentenced to pay a
fine of not more than $1,000 plus costs and, in default of payment
of said fine and costs, to a term of imprisonment not to exceed 30
days. Each day that a violation of this part continues or each section
of this part which shall be found to have been violated shall constitute
a separate offense.
