Road noise in residential buildings has become one of the most important subject. Recently, in new regulation for measurement and prediction of noise, noise impact assessment is required before building construction. But there have been few studies on applying calculation method reasonably. In many countries, noise calculation method are used as a tool for spacial and building planning purposes. In this study, the road noise was predicted using two calculation models, RLS-90 and CRTN. And the results by traffic conditions such as traffic volume, vehicle speed and percentage of heavy vehicles were analyzed and mutually compared. |
