This building research survey is an analysis of the social nuisance caused by urban motor ways and their noise. The Traffic Noise Index is used to indicate traffic noises and their effects on architectural designs and planning, while suggesting the need for more and better window insulation and acoustical barriers. Overall concern is for--(1) finding unacceptable noise levels, (2) discovering how traffic noise is propagated, and (3) determining effective traffic noise control for buildings. Graphs and charts are used to distinguish the relationship between noise levels and distances. (TG)
