[HISTORY: Adopted by the Village Board of the Village of Superior at time of adoption of Code (see Ch. 1, General Provisions, Art. II). Amendments noted where applicable.]
It shall be unlawful for any person to make, continue or cause to be made or continued any loud and unnecessary noise.
The following acts are declared to be loud, disturbing and unnecessary noises in violation of this chapter, but this enumeration shall not be deemed to be exclusive:
Horns and signaling devices. The sounding of any horn or signaling device on any automobile, motorcycle or other vehicle on any street or public place in the Village for longer than three seconds in any period of one minute or less, except as a danger warning; the creation of any unreasonably loud or harsh sound by means of any signaling device and the sounding of any plainly audible device for an unnecessary and unreasonable period of time; the use of any signaling device except one operated by hand or electricity; the use of any horn, whistle or other device operated by engine exhaust; and the use of any signaling device when traffic is for any reason held up.
Radios, phonographs and similar devices. The using, operating or permitting to be played, used or operated of any radio receiving set, musical instrument, phonograph or other machine or device for the producing or reproducing of sound in a loud and unnecessary manner. The operation of any set, instrument, phonograph, machine or device between the hours of 10:00 p.m. and 7:00 a.m. in a manner as to be plainly audible at the property line of the building, structure or vehicle in which it is located shall be prima facie evidence of a violation of this subsection.
Loudspeakers or amplifiers for advertising. The using, operating or permitting to be played, used or operated of any radio receiving set, musical instrument, phonograph, loudspeaker, sound amplifier or other machine or device for the producing or reproducing of sound which is cast upon the public streets for the purpose of commercial advertising or attracting attention of the public to any building or structure. Announcements over loudspeakers can only be made by the announcer in person and without the aid of any mechanical device.
Animals and birds. The keeping of any animal or bird which causes frequent or long-continued unnecessary noise.
Steam whistles. The blowing of any steam whistle attached to any stationary boiler except to give notice of the time to begin or stop work or as a warning of fire or danger or upon request of proper Village authorities.
Exhausts. The discharge into the open air of the exhaust of any steam engine, stationary internal combustion engine or motorboat except through a muffler or other device which will effectively prevent loud or explosive noises therefrom.
Construction or repair of buildings. The erection (including excavation), demolition, alteration or repair of any building, as well as the operation of any pile driver, steam shovel, pneumatic hammer, derrick, steam or electric hoist, or any other similar equipment attended by loud or unusual noise, other than between the hours of 7:00 a.m. and 10:00 p.m. on weekdays; provided, however, that the Building Inspector shall have the authority, upon determining that the loss or inconvenience which would result to any party in interest would be extraordinary and of such nature as to warrant special consideration, to grant a permit for a period necessary within which time such work and operation may take place within the hours of 10:00 p.m. to 7:00 a.m.
Schools, courts, churches and hospitals. The creation of any excessive noise on any street adjacent to any school, institution of learning, church or court while in use, or adjacent to any hospital, which unreasonably interferes with the normal operation of that institution, or which disturbs or unduly annoys patients in the hospital, provided that conspicuous signs are displayed in those streets indicating a school, hospital or court street.
Compression brakes. The use of motor vehicle brakes which are in any way activated or operated by the compression of the engine of any such motor vehicle or any unit or part thereof. It shall be an affirmative defense to prosecution under this subsection that said compression brakes were applied in an emergency and were necessary for the protection of persons and/or property. The Director of Public Works is authorized and directed to post appropriate signs consistent with the provisions of this subsection.
The provisions of this chapter shall not apply to:
Any vehicle of the Village while engaged in necessary public business.
Excavations or repairs of streets or other public construction by or on behalf of the Village, county, or state at night when public welfare and convenience render it impossible to perform such work during the day.
The reasonable use of amplifiers or loudspeakers in the course of public addresses which are noncommercial in nature.
Maximum permissible sound levels.
Noise from a stationary source shall not exceed the following standards for maximum sound-pressure levels measured at the property line:
Ambient noise is the all-encompassing noise associated with a given source, usually being a composite of sounds with many sources near and far, but excluding the noise source being measured. Ambient noise is a factor, and the subject noise shall exceed the ambient noise by five db in any octave band to be designated excessive.
Construction noise. Construction equipment in any zone may be operated between the hours of 7:00 a.m. and 7:00 p.m., provided that said equipment does not exceed a maximum sound level of 80 db measured at the property line of the location at which said equipment is in use.
Noise in residential districts. In residential zones, the person in violation of this section shall be ordered to reduce the sound pressure to acceptable levels immediately by the monitoring officer.
Operation of certain equipment. Lawn mowers, chain saws, powered garden equipment, electric insect-killing/-repelling devices, and other nonconstruction maintenance equipment shall be operated only during the hours between 7:00 a.m. and 9:00 p.m. unless within the specified noise levels measured at the property line of the location at which said equipment is in use.
Exemptions. Operations of emergency equipment shall be exempt from this chapter. Snowblowers not operated on a commercial basis shall be exempt from this chapter when used to gain access to a Village street. "Emergency equipment" shall include ambulance, police, fire, snow removal, civil defense sirens, etc., necessary for the health, safety, and protection of the citizens of the Village.
Methods of measuring noise.
Equipment. Noise measurement shall be made with a sound-level meter.
Location of noise meter. Noise measurement shall be made at the nearest lot line of the premises from which a noise complaint is received. The noise meter shall be placed at a height of at least three feet above the ground and at least three feet away from walls, barriers, obstructions and all other sound-reflective surfaces.
Appeals. The Village Board may grant an exemption to individuals proving evidence of substantial hardship. Evidence that reasonable technological attempts have been made to correct the problem shall be considered grounds for granting an exemption to this chapter for existing industries.
