摘要
随着城市快速道路、轨道交通建设的增多,道路交通噪声对城市居住小区的影响问题日益突出,已成为绿色生态小区声环境质量保障的热点问题。对重庆某住宅小区环境交通噪声影响进行监测,结果显示交通噪声主要呈现中低频噪声特性,峰值出现在63Hz频率周围。根据居住小区声环境控制目标,对小区噪声边界进行模拟分析,提出了声屏障降噪措施,分析了声屏障设计高度、安装位置、形状和材料,综合声景观设计,达到居住小区总体声环境需求。基于实际工程案例的声屏障优化设计分析,可供山地城市绿色生态住宅小区声环境规划设计参考。
With the increase of urban express roads and rail transit construction,traffic noise is posing growing challenges to urban residential areas,which has become a hot issue in the sound environment quality assurance of green ecological communities.This paper monitored the impact of traffic noise on the environment of a residential community in Chongqing.The results showed that the traffic noise mainly exhibited low-mid-frequency noise characteristics,and the peak appeared at around the 63 Hz frequency.According to the acoustic environment control target of the residential community,the noise boundary of the community was simulated,and the noise reduction measures of the sound barrier were proposed,with the design height,instal-lation position,shape and material of the acoustic barrier analyzed.Combined with the soundscape design,the overall acoustic environment needs of the residential community were met.Based on the analysis of sound barrier optimization design in actual cases,this study can be used as reference for the acoustic environment planning and design of the green ecological residential community in mountainous cities.
