13-3-10: PERFORMANCE STANDARDS:
Any use established in any zoning district shall be operated so as to comply with the performance standard regulations prescribed in subsection A of this section.
   A.   Noise:
      1.   Sound Levels: Sounds levels shall be measured with a sound level meter manufactured according to standards prescribed by the American National Standards Institute (ANSI). Measurements shall be made using a digital decibel meter. Impulse type noises shall be subject to the performance standards prescribed in this subsection A, provided that such noises shall be capable of being accurately measured. Noises incapable of being so measured, such as those of an irregular and intermittent nature, shall be controlled so as not to become a nuisance to adjacent uses. At any point on or beyond the boundary line of the district designated below, the sound pressure level of any operation or plant (other than background noises produced by sources not under control of this subsection A, such as the operation of motor vehicles or other transportation facilities) shall not exceed the decibel limits in the table below:

      2.   General Requirements:
         a.   Sound Measurement Setback Requirement: All sound measurement readings must be set up not less than twenty five feet (25') (7.6 meters) from the property line noise source. The twenty five foot (25') (7.6 meter) setback requirement is from the noise source and not the property line unless the noise source is contiguous to the property line.
         b.   Exempt Activities: Activities exempt from these provisions include the operation of motor vehicles or other transportation facilities; snow removal equipment; church bells/chimes; residential air conditioning units (installed and operating in accordance to manufacturer's specifications).
         c.   Unnecessary Noise Standards: The following activities are declared to be loud, disturbing and unnecessary noises in violation of this subsection A:
            (1)   Horns And Signaling Devices: The sounding of any horn or signaling device on any automobile or other motor vehicle on any street or public place of the village except as a danger warning.
            (2)   Animals Or Birds: The keeping of any animal or bird which, by causing frequent or continued noise, shall disturb the comfort or repose of any persons in the vicinity.
            (3)   Exhausts: The discharge into the open air of the exhaust of any engine, stationary combustion machine, generator, motorboat or motor vehicle except through a muffler or other device, which will effectively prevent loud noises therefrom. The use of emergency generators and other backup power sources would not apply to reasonable use during an emergency situation or during testing.
            (4)   Loading: The creation of loud and excessive noise in connection with the loading or unloading of any vehicles.
         d.   Additional Requirements; Lawn Mowing/Maintenance: It shall be unlawful to cause or make loud noise through the operation of lawn maintenance equipment including, but not limited to, lawn mowers, lawn blowers and tractors before seven o'clock (7:00) A.M. and after dusk on any day during the week. This restriction shall not apply to golf course, park district or forest preserve maintenance operations.
   B.   Other Performance Standards: Any use established in the various residence and business districts shall be operated so as to comply with the performance standard regulations set forth in section 13-10-3 of this title. (Ord. G-678, 6-26-2001; Ord. G-863, 7-22-2008)
