中文摘要：

街道空间是城市重要的公共空间,其声环境品质与城市居民的生活息息相关。随着“密路网,小街区”规划政策的逐步实施,支路将承担更多的交通功能,车辆增加,噪声加大,由此支路两侧建筑对噪声往复反射所形成的“声峡谷”效应将更加明显。设计师及管理者应采取针对性的噪声控制措施。文中从建筑设计角度,总结前人经验,对“声峡谷”内噪声的优化途径进行总结和探讨,以期对街道空间现状做出改善,对未来建筑设计提供借鉴。

英文摘要：

Street space is an important public space in the city. With the implementation of new planning policy of ＂ dense road network, small block＂, city branches take more traffic functions with more vehicles and more noise. Thus the effect of ＂sound canyon＂ becomes more obvious, which makes the acoustic characteristics need to be focused and new noise control measures should be taken. From the perspective of architectural design, the article sums up the existing research, analyzes the main influence factors of canyon noise and summarizes the optimization approaches in order to make improvements to present situation of street space and provide guidance for the future architectural design.
