临街建筑声环境的研究与改善

Study and improvement on the noise environment of the roadside buildings

临街建筑的声环境已经成为当前深受关注又迫切需要解决好的问题之一.针对当前中国中等城市实际车流量和道路情况,从理论上建立了城市道路交通噪声声场模型,并选取有代表性的交通干道临街建筑,作详细的噪声同步测量.从理论和实测两方面对临街建筑噪声分布及其相关影响因素进行了定量分析,并在此基础上提出了改善临街建筑声环境的一系列对策建议.

The noise environment for the roadside buildings has become one problems of immediate concern which calls for proper solution. The authors of this paper, after giving the direct sound for typical magnitude of traffic flow on average speed and the reverberant sound in typical artery, set up the theoretical model for the noise field in urban streets, which is suitable for Chinese conditions and has never been done before. The paper, at the same time, investigates the noise of the building facing the typical artery, and finally makes a quantitative analysis on the noise distribution and the influential factors according to the measurement and theories. Based on the detailed analysis, the authors finally put forward a series of strategy to improve the environment for the roadside buildings in cities.
