Summaries are presented of the four workshop sessions which addressed the following topics: (1) motor vehicle noise sources and suppression; (2) reduction of motor vehicle noise at the source; (3) control of motor vehicle noise at the source; and (4) state and local regulations. The first session established the extent to which motor vehicle noise contributes to total environmental noise. Highway vehicles were classified according to their noise emissions and the extent to which each participates in creating the overall noise on a roadway. Within each class of vehicles, the important noise sources in the vehicle and noise control alternatives were identified. Consideration was given to several possible combinations and trade-offs provided by using both controls at the noise source and barriers to abate highway noise. The second session explored the extent to which it is possible to determine the effect that noise reductions in specific categories of motor vehicles have on overall traffic noise levels, and a timetable for the reduction of motor vehicle noise levels. The purpose of the third session was to identify and analyze the critical elements needed to accomplish an effective source-control program. Speakers during this session provided specific information in the following areas: interstate enforcement; integration of federal, state, and local programs; in-use and new-product source-control strategies; and community benefit from noise source control. In the fourth session a road map of administrative decisions was suggested, and three case histories on noise-control programs in Florida, New Jersey, and Maryland were presented to illustrate different routes toward the goal of vehicle noise control. These programs and those in California and Chicago show how each route is tailored to the uniqueness of each individual jurisdiction.
