摘要

广场舞作为一类典型声源,对城市开放空间中声景观的影响还未得到深入研究。本文通过对三类典型广场的问卷调查和声环境测量,分析了广场舞在这些区域内对声级、声源和声舒适度的影响。结果表明,在不同类型的广场中,广场舞声级在10-15m的范围内分别衰减了5.1d BA至3.4d BA;在声音感知方面,在城市公园广场中,当距广场舞声源2-15m和15-30m范围内时,使用者听到的广场舞音乐声分别占听到声音频次总数的64.5%和41.5%;在声舒适度评价方面,广场舞可将城市公共广场中的行人的声舒适度提高了0.4,而居住区广场中却将行人的声舒适度降低了0.7。综上所述,选择合适的场地进行广场舞活动可有效改善城市开放空间的声景观。
Square dance activities, as a kind of typical sound sources, which may effect on soundscape in urban open spaces, have not been deeply studied. Based on a questionnaire survey and acoustic measurements in 3 typical squares, the effect of square dance activities on sound pressure level, sound source and acoustic comfort in urban open spaces has been analyzed in present study. The results demonstrated that the sound pressure level can be reduced from 5.1 d BA to 3.4 d BA in different types of urban open spaces at the distance of 10-15m; In terms of the perception of sound, the frequency of square dance source which users hear is 64.5% of all at 2-15 m in park-square, while it is 41.5% at 15-30m; In terms of evaluation of acoustic comfort, the acoustic comfort of persons who passing by in public square can be increased 0.4 by square dance activities, while acoustic comfort of persons who passing by in residential square can be reduced 0.7 by square dance activities. In summary, the soundscape in different types of urban open spaces can be changed by square dance activities.
