A series of tests have been carried out at six sites for the evaluation of noise barriers to determine their relative effectiveness. Two barriers were metal, two were wooden, and one was concrete. One site, used for reference, had no barrier. The effectiveness of the measurements was somewhat reduced by low-flying aircraft and by a high noise floor on one microphone. However, because a sophisticated data collection system was used, useful results were obtained. These results indicate that all of the barriers perform up to the relevant design curves.
