ASJ RTN-Model 2003, which is generally used for the evaluation of the Environmental Quality Standards for Noise in Japan, estimates the averaged noise levels as the representative value in each estimate section. However, the noise level of each building is greatly changed by the arrangement of buildings. Therefore, it is necessary for the evaluation of the Standards to take the distribution of noise levels in the estimate sections into consideration. From the above viewpoint, we propose a new concept to adopt the highest frequency level of insertion loss of road traffic noise as the representative value of each estimate section, and a simple method to predict the highest frequency level of insertion loss is presented based on the simulation of the insertion losses caused by detached houses by the authors' method(F2006).
