校园周边交通噪声环境调查与仿真研究

Investigation on the Traffic Noise Environment around Campus and Study of Its Simulation

现代城市中的噪声已经成为影响人们生活和工作的一个重要因素,校园周边的交通噪声问题也日益突出。选择典型校园,对其周边交通噪声进行实测,并利用Cadna/A噪声预测软件进行仿真分析,绘制出校园周边的交通噪声影响图。对比分析的结果表明,仿真与实地测量值基本吻合。提出了控制校园周边交通噪声的建议措施。

The noise in modern city has seriously affected people’s life and work,and the problem of traffic noise around the campus is increasingly prominent as well. By selecting a typical campus in Yangzhou city,this article measures the surrounding traffic noise and gives the simulated analysis with the noise prediction software Cadna/A,drawing the traffic noise effect around the campus. The result from analysis and comparison shows that the measured value basically agrees with the simulation. Finally,it proposes some measures on controlling the traffic noise around campus.
