For purposes of this chapter, unless otherwise required by the
context, the following words and phrases shall have the meanings respectively
ascribed to them by this section:
A-WEIGHTED SOUND PRESSURE LEVEL
The sound pressure level as measured on a sound level meter
using the A-weighted scale and programmed to slow response. The level
so read shall be designated dB(A) or dBA.
dBA
The sound pressure level as measured on a sound meter set
to slow response and to the A-weighted scale to approximate the frequency
response of the human auditory system.
DEVICE
Any mechanism which is intended to produce or which actually
produces noise when operated or handled.
LAV (dBA)
The average A-weighted sound pressure level measured over
a reasonable period not less than five minutes.
NOISE
Any sound which may cause or tend to cause an adverse psychological
or physiological effect on human beings.
NOISE SOURCE
Any equipment, motor vehicle, motorcycle or facility, fixed
or movable, capable of emitting sound beyond the property boundary
of the property on which the equipment is used, but not including
motor vehicles or motorcycles operated on public rights-of-way.
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.
SOUND LEVEL METER
An instrument to measure sound pressure levels which shall
meet or exceed performance standards for a Type 2 meter as specified
by the American National Standards Institute.
SOUND PRESSURE
The instantaneous difference between the actual pressure
and the average or barometric pressure at a given point in space.
The following acts, among others, are declared to be noise disturbances
in violation of this chapter, but said enumeration shall not be deemed
to be exclusive, namely:
A. Blowing horns: to sound any horn or signal device in any other manner
or circumstances or for any other purpose than required by the laws
of the state.
B. Racing engine: to race the engine of any motor or all-terrain or
motorcycle vehicle while such vehicle is not in motion, except when
necessary to do so in the course of repairing, adjusting or testing
the same, between the hours of 10:00 p.m. and 7:00 a.m.
C. Use of vehicle: operating any motor vehicle, including any all-terrain
vehicle or motorcycle or engine, stationary or moving instrument,
whether on public or private property, not meeting the standards of
Title 46.2 of the Code of Virginia pertaining to mufflers and exhaust
systems.
D. It shall be unlawful for any person to use any device for the production
or reproduction of sound which is cast upon public streets or lands
for the purpose of commercial advertising.
E. Radios, phonographs, etc. The using or operating of, or permitting
to be placed, used or operated, whether in a building, structure,
motor vehicle or otherwise, any radio receiving set, musical instrument,
phonograph or other machine or device for the producing or reproducing
of sound in such a manner as to be plainly audible at a distance of
the greater of either the property line of the property on which such
set, etc., is being operated or used or 50 feet from said set, instrument,
phonograph, machine or device, if not located in a building, structure
or vehicle or 50 feet from the building, structure or vehicle in which
it is located or through partitions common to two persons within a
building shall be a violation of this chapter.
F. Exhaust noises: the discharge into the open air of the exhaust of
any steam engine, stationary or moving, or internal combustion engine,
motorboat or motor vehicle, except through a muffler or other device
which will effectively prevent unreasonably loud or explosive noises
therefrom. For purposes of this section, "muffler" is defined as an
apparatus consisting of a series of chambers or baffle plates designed
for the purpose of transmitting gases while effectively reducing sound
emanating from such apparatus to a reasonable level.
G. Construction or repairing of buildings: the erection, including excavating,
demolition, alteration or repair, of any building or structure between
the hours of 10:00 p.m. and 6:00 a.m., except in case of urgent necessity
in the interest of public health and safety, and then only with a
permit from the Building Official, which permit may be granted for
a period not to exceed three days or less while the emergency continues
and which permit may be renewed for periods of three days or less
while the emergency continues.
[Amended 4-17-2012]
H. Pets: allowing an animal to create howling, barking, whining, meowing, squawking or other such noises which are plainly audible across a property boundary or through partitions common to two residences within a building and that take place continuously or repeatedly during a period of at least 15 minutes in duration between 7:00 a.m. and 10:00 p.m. or during a period of at least 10 minutes in duration between 10:00 p.m. and 7:00 a.m.; provided, however, that animal noises on property subject to a conditional use permit for a kennel shall be governed exclusively by §
180-49 of the Warren County Code.
[Amended 12-20-2011]
It shall be unlawful for any person to operate, or permit to
be operated, any noise source in such a manner that the noise source
emits a sound pressure level which exceeds the limits set forth below
when measured on property other than that on which the noise source
is located. The category of applicable sound pressure limits shall
be determined by the zoning district classification of the property
on which the noise is measured, not the property on which the noise
is produced.
