The revised environmental quality standards for noise provide that the status of noise in the "areas facing roads" should be evaluated by calculating the number and the ratio of residences at which LAeq excesses the standards. Therefore calculating road traffic noise in large built-up areas becomes increasingly important. This paper presents methods for calculating section-averaged equivalent continuous A-weighted sound pressure level (SA·LAeq) in the built-up areas facing a surface street and a highway with noise barriers. In these methods, the built-up areas are classified into a row of buildings directly facing the road and the other buildings behind it. The values of SA·LAeq in the areas are calculated by summing the contributions from the sound paths propagating among buildings and over them. The validity of the methods presented here is verified by model experiments and field surveys.
