The Chicago Noise Ordinance became effective July, 1971. The Ordinance provides a step reduction in noise levels from 92 dBA for motorcycles, 88 dBA for vehicles to 75 dBA for all vehicles in 1980. 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. The most difficult problem encountered has been the enforcement of motorcycle noise controls.
