Motor Vehicle Noise Generation and Potential Abatement 720273

In May 1969, the Department of Transportation initiated a study on the magnitude of the transportation noise problem and its potential abatement. This study has resulted in the first comprehensive review and analysis of transportation noise in the United States.
As an aid in conducting the analysis, and for continuing use in noise reduction efforts, four computer simulation models were developed. By using the models, it was possible to establish the noise levels which might be expected for different transportation modes as a function of the traffic characteristics peculiar to that mode. In addition, an understanding was developed of the technical, economic, and legal limits of potential abatement means for each transportation mode. The study also dealt with the responsibility and ability of public and private groups to provide the necessary implementation programs to achieve noise abatement. The need for government standards and regulations was reviewed as was the need for additional research and development of successful means for reducing noise.
This paper presents the results of the noted study as they relate to motor vehicles, and the program of the Office of Noise Abatement of the Office of the Secretary, Department of Transportation, for achieving reasonable noise reduction consistent with the Secretary's desire for an integrated transportation system.
