Abstract:Road traffic noise is the main source of sound environment in urban open public spaces in China. Current research on sound environment perception of urban open public spaces under the influence of various sound sources has achieved fruitful results, while the research on urban open public spaces dominated by sole traffic noise need discussing further. In this paper, the square closed to the arterial road was sampled. According to the sound pressure level interval (70dBA, 60dBA, 50dBA), three measurement areas were selected along the direction perpendicular to the arterial road. Semantic differential method was used to assess the perception of sound environment, and then factor analysis was adopted to investigate the dimensional composition of the sound environment and its variation with traffic noise attenuation. The result showed that whether analysing the three areas separately or comprehensively, two relatively stable dimensions of sound environment perception were obtained. Dimension I reflecting “Relaxation ?information was the most important in all areas. Dimension II reflecting the “Spatiality ?information became more and more important with the attenuation of traffic noise. The study provided reference for the design of planning and landscape in urban open public spaces. © 25th International Congress on Sound and Vibration 2018, ICSV 2018: Hiroshima Calling.
