As the environmental quality standards for noise were revised, it becomes increasingly important to predict road traffic noise behind roadside buildings. This paper presents methods for calculating LAeq at specific individual positions behind a building directly facing a surface road and for calculating section-averaged equivalent continuous A-weighted sound pressure level (SA·LAeq) behind a row of buildings belong the road. The validity of the methods presented here is verified by model experiments. In addition, the authors analyze the relationship between the calculated values and the parameters for the calculations such as height of the building, opening ratio of the row of buildings and so on. As a result, it is shown that the calculation methods can be simplified at some positions of receivers.
