• The purpose of this paper is to present a simple method for predicting the excess attenuation of road traffic noise by detached houses. The Acoustical Society of Japan (ASJ) presents one method ; however, it cannot estimate noise levels at specific individual points in residential areas. In this paper, therefore, an experiment is performed with a one-twentieth scale model and a new empirical formula for excess attenuation, based on only five parameters, is proposed. The validity of the formula is verified through additional experiments, a comparison with the current method, and noise measurements in actual residential areas. This new and simple method is applicable to evaluations of environmental quality standards for noise.
