a. An apartment or hallway of a multifamily building adjacent to a unit where the device is operating. b. The property line of the real property on which the device is being operated. c. A distance of 50 feet from any motor vehicle in which the device is operating. (32) To operate or to cause to be operated, but not limited to, the use of any noise creating blower or power fan, internal combustion engine, air compressor or steam engine, automobile, motorcycle, snowmobile, motor boat, motor bike, scooter, recreational vehicle, all terrain vehicle, off - highway motorcycle, off -road vehicle, go -cart, or remote controlled airplane, boat, or other vehicle powered by an engine or motor, the operation of which causes noise, unless the noise from the blower or fan is muffled and such engine or compressor is equipped with a muffler device sufficient to deaden and effectively prevent such noise so that the noise shall not annoy, disturb or affect the comfortable enjoyment of life or property. a. Sound levels. No person shall operate or cause or permit to be operated any source of noise in such a manner as to create a noise level exceeding the limit set in Table 1.

The following procedures must be used to obtain a representative sound level measurement by the use of a sound measuring device: 1. A decibel meter will be used to obtain readings and be used as evidence. 2. The operator of the device has sufficient training to properly operate the equipment and can testify as to the manner in which the device was set up and operated. 3. The device is operated with minimal distortion or interference from outside sources; and has been certified as being accurate and reliable. 4. Measurements must be made at least three feet off the ground or surface and away from natural or artificial structures which would prevent an accurate measurement. 5. Measurements must be made using an A- weighting and fast response characteristics of the sound measuring device as specified in American National Standards Institute S1.4-1983. 6. Measurements must not be made in sustained winds or in precipitation which results in a difference of less than ten decibels between the background noise level and the noise source being measured. 7. Measurements must be made using a microphone which is protected from ambient conditions which would prevent an accurate measurement. 8. Measurement must be made from the property of the person making the complaint, when applicable. (33) Tracks and trails for riding motor vehicles are not allowed in a residential area unless said track or trail is: a. 1,000 feet from any residence except that of the owner; and b.
