This chapter may be cited as the "Noise Control Ordinance of
the Town of Louisa." It shall be applicable to the control of noises
originating within the Town limits.
The Council hereby finds and declares that excessive sound is
a serious hazard to the public health, welfare, peace and safety and
the quality of life; that a substantial body of science and technology
exists by which excessive sound may be substantially abated; that
the people have a right to and should be ensured an environment free
from excessive sound that may jeopardize the public health, welfare,
peace and safety or degrade the quality of life; and that it is the
policy of the Town to prevent such excessive sound.
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:
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) or dBA.
BACKGROUND NOISE LEVEL
The aggregate of all sound sources impacting at the place
where a specific sound generation is measured or evaluated, excluding
the specific sound generation itself.
DECIBEL (dB)
A unit for measuring the volume of a sound, 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).
DOWNTOWN BUSINESS DISTRICT
For the purposes of this chapter, that portion of the Town's
downtown business district bordered by railroad tracks on the north,
a Town entrance on the south, a Town entrance on the west, and a Town
entrance on the east, consisting of public streets, public sidewalks
and pedestrian walkways, public open spaces, outdoor cafe areas operated
under any permit granted by the Town, public or privately owned alleys

SOUND GENERATION
Any conduct, activity or operation, whether human, mechanical,
electronic or other, and whether continuous, intermittent or sporadic,
and whether stationary or ambulatory in nature, which produces or
results in an audible sound.
SOUND LEVEL
The weighted sound pressure level obtained by the use of
a sound level meter and the A-frequency weighting network, as specified
in American National Standards Institute specifications for sound
level meters.
SOUND LEVEL METER
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 noise control program established by this chapter shall
be enforced and administered by the Police Department with the assistance
of other Town departments as required.
No provisions of this chapter shall apply to the emission of
