STATE OF THE PRACTICE: ENVIRONMENTAL NOISE MEASUREMENTS

When the FHWA noise standards were first promulgated, there was little standardization in noise measurement equipment or procedures as they pertained to traffic noise. Since then, FHWA training courses and demonstration project workshops have provided a more consistent picture of the field and have served as "technology transfer" agents. However, no comprehensive assessment of the state-of-the-practice had been made. A questionnaire was circulated in December, 1982, by TRB Committee A2H01, Instrumentation Systems, Principles and Applications, to gather and synthesize this information. Responses were received from 44 state DOTs (including the District of Columbia and Puerto Rico), four Canadian provinces, two counties, the Federal Aviation Administration, and the Colorado Department of Health, for a total of 52 responses. This report presents the results of the survey. It should be noted that while questionnaires were not returned by eight state DOTs, that lack of response should not be taken as an indication of the absence of measurement equipment or programs in those states. Indeed, at least two have a good deal of measurement equipment. This report is divided into six additional sections. Sections 2, 3 and 4 address personnel, blends much of the information from the previous sections as it discusses monitoring experience in nine separate areas such as ambient noise, noise barrier effectiveness, aviation noise, and vibration. Section 6 summarizes comments on research reports and other items of interest to the respondents, while Section 7 discusses research needs as seen by the respondents. Section 8 provides a summary. In addition, two appendices provide detailed information on measurement reports and manuals and research needs. (Author)
