[HISTORY: Adopted by the Town Council of the Town of Louisa 6-20-2017. Amendments noted where applicable.]
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 and any privately owned outdoor property that is open to the public for commercial or recreational purposes.

A. 
Any person who violates any provision of this chapter shall be deemed to be guilty of a Class 4 misdemeanor.

A. 
Nighttime. No person shall permit, operate or cause any source of sound to create a sound level in a residential zone or within any residential building during the hours between 10:00 p.m. and 6:00 a.m. in excess of 55 dB(A) when measured at or outside the property boundary.

Measurements in multifamily structures. In a structure used as a multifamily dwelling, the Police Department may take measurements to determine sound levels from common areas within or outside the structure or from other dwelling units within the structure, when requested to do so by the owner or tenant in possession and control thereof. Such measurement shall be taken at a point at least four feet from the wall, ceiling or floor nearest the noise source, with doors to the receiving area closed and windows in the normal position for the season.
D. 
Exemptions. The following activities or sources of noise shall be exempt from the daytime prohibition set forth in Subsection B of this section:

C. 
The prohibitions set forth within this section shall not apply to any sound generation which occurs:

A. 
The decibel level of any noise regulated by this chapter may be measured by the use of a sound level meter which measures sound pressure levels. Such measurements shall be accepted as prima facie evidence of the level of noise at issue in any court or legal proceeding to enforce the provisions of this chapter.
B. 
The accuracy of the sound level meter may be tested by a calibrator. Any sworn report of the results of any test of the calibrator for the accuracy of a sound level meter shall be admissible in court in any criminal or civil proceeding, as evidence of the facts therein stated.
