Abstract:
This paper addresses the evaluation of noise impacts from highway projects in Massachusetts. It describes the process and level of analysis prepared for environmental and design documents, analyzes factors used in determining areas to be impacted by noise, and discusses the feasibility of mitigating measures. In addition, the paper presents a case history of a noise barrier construction project to illustrate the effectiveness of the process. Noise measurement and prediction methodology together with the criteria, engineering, and economic considerations which led to the decision to construct this noise barrier are discussed. The public participation process is outlined, including the format of the public meeting and issues of concern. The discussion concludes with a brief description of proposed procedures to evaluate noise reduction and public acceptance of the barrier.
