摘　　要：为了解浙江大学一学生宿舍的声环境状况,并探究宿舍围护构件隔声性能,文章通过对学生宿舍室内外环境噪声进行现场测量,结合Cadna/A软件对交通噪声进行模拟分析,通过问卷调查主要噪声来源以及学生满意度,同时对当前研究较少的围护构件隔声量进行测试。结果表明,交通噪声是室外主要噪声源;宿舍隔墙、门窗等围护构件隔声性能不佳,而采用强化木地板的楼板计权标准化撞击声压级为59dB,可明显改善楼板撞击声。该文章的测量可为学生宿舍改进设计提供一定的参考。In order to understand the acoustic environment of a student dormitory of Zhejiang University,and explore the sound insulation performance of dormitory envelope components,this paper conducted on-site measurement of indoor and outdoor environmental noise of the student dormitory,combined with Cadna/A software to simulate and analyze traffic noise,and conducted questionnaire survey on the main noise sources and student satisfaction.At the same time,the sound insulation of the envelope is tested.The results show that traffic noise is the two main outdoor noise source.The sound insulation performance of dormitory walls,doors and windows and other enclosure components is not good,and the standardized impact pressure level of the floor after the adoption of laminate wood flooring is 59dB,which can obviously improve the impact sound of the floor.The measurement in this paper can provide some reference for the improvement design of the student dormitory.
