ASSESSMENT AND PREDICTION OF TRAFFIC NOISE

Noise from highway traffic was measured at thirty-six different sites in Calgary and Edmonton, Alberta. The measurements were made using a multimicrophone system which could sample the output from up to eight microphones. The microphones were placed in an array at right angles to the highway at various heights up to 40 ft above the ground and at distances of up to 300 ft from the edge of the pavement. The measurements were made for a variety of traffic densities and truck/automobile mixes. Vehicle speeds ranged from 30 to 60 miles an hour. A limited range of different types of terrain was included in the experiments. The results of these experiments are briefly described and summarized. The data collected has been compared with existing traffic noise prediction methods from two points of view, i.e.: the level of the noise at or close to the curbside, the levels of the noise as it was attenuated in traveling to nearby residences.
