TIMETABLE AND OBSTACLES FOR SOURCE CONTROL IN THE CITY OF CHICAGO

The Chicago Noise Ordinance became effective July 1, 1971. The ordinance provides for a step reduction in noise levels from 92 dBA for motorcycles, 88 dBA for vehicles of 8,000 lb (454 kg) or more, and 86 dBA for cars and other motor vehicles downward in 4 increments to 75 dBA for all vehicles by January 1, 1980. Each manufacturer selling vehicles in Chicago must certify in writing that they comply with these levels. This program has thus far been successful and has even resulted in some moderls being taken off the Chicago market in a recent year. A problem encountered has been the lack of appreciation by the judiciary for the seriousness of vehicle noise as an urban menace. Few of the tickets issued result in fines because it is felt that loss of a day of work is sufficient punishment for a violator and a noise violation appears to be not so significant as a moving violation. The most difficult problem encountered has been the enforcement of motorcycle noise controls. Consideration is being given to amending the noise ordinance to prohibit the sale of modification equipment in the City of Chicago, but passage of such a regulation in Chicago and not in the state would negate its benefits. Another source of noise presently under consideration in Chicago is the emergency vehicle. An ordinance specifying maximum noise levels permissible for these vehicles in being considered.
