PREDICTION AND EVALUATION METHODS FOR ROAD TRAFFIC NOISE IN BUILT-UP AREAS
Since the Japanese environmental quality standards for noise were revised in 1998, it has become increasingly important to predict and evaluate the road traffic noise in built-up areas in Japan. This paper presents a method of calculating LAeq averaged in an evaluation section behind buildings facing an arterial road. In this method, the buildings are classified into the first row of buildings directly facing the road and the remaining buildings behind them. Then the values of the sectional energy-averaged LAeq are simpley calculated mainly according to the density of the buildings and the distance from the road to the evaluation section, by summing the sound-energy contributions from the sound paths propagating through the buildings and over them. The validity of the method presented herein has been verified by measured data in field surveys. For the covering abstract see ITRD E107776.
