| 摘 要： | 交通噪声对住宅小区的影响分析，除考虑直达声和反射声的影响外，还应加入衍射声场的作用。该文建立了典型住宅区中噪声衰减的完整理论模型，计算分析了交通噪声对建筑群纵深的影响，并对无规则分布的建筑群中声衰减作了定性分析。还以典型建筑群为例，对已知建筑布局下噪声在其中的衰减特征，作了说明和验证。

| Abstract: | With the diffraction sound field consideration, effect of traffic noise on residential quarter has been studied, and comprehensive models for prediction of affenuation of noise in residental quarter were given. With the given model, the noise affenuation in different types of building complex was analyzed and compared with measure results. |
