Soundscape characterization in outdoor public spaces in urban high- rise residential blocks

摘要

Outdoor public spaces in high-rise residential districts are essential components in modern high-density cities, and acoustic comfort in those spaces are important for enhancing personal relaxation and community communications. However, while considerable previous works were carried out from the viewpoint of noise control, their overall sound environment perception has not been paid sufficient attention. Therefore, this study aims to characterize the soundscape dimensions of outdoor public spaces in urban high-rise residential districts, and to explore the effect of soundscape dimensions on the overall soundscape satisfaction. A detailed soundscape survey was conducted in the outdoor public space of a typical residential block. The semantic differential analysis of soundscape dimensions shows that while the soundscape in outdoor public spaces of high-rise residential districts is rather complicated, five major dimensions are identified, including pleasantness, familiarity, strength, stability, and spatiality. Consequently, effect of the dimensions on the overall soundscape satisfaction was briefly discussed.
