• Abstract:
  Traffic noise has recently been described as a form of environmental pollution. Society now demands that the highway engineer consider traffic noise effects for both future and existing highways. One method of reducing traffic noise to acceptable levels is to construct acoustically opaque barrier walls. The objective of this research was to review the methods of reducing traffic noise and the types of barriers and acoustical materials that might be used to reduce this noise. Two sites were evaluated, one having data already available, while the other required the measurement of traffic noise in the field. These results were compared with those calculated using formulae developed by other researchers. This report reviews the factors that affect noise attenuation by barrier walls and presents graphs that can be used by the highway engineer to calculate the reduction of traffic noise due to barrier walls.
