摘　　要：为研究输电线风噪声对山地居住环境的影响,采用声场仿真的方法,对周壤—腾蛟220k V输电线风噪声进行了分析。结果表明:在复杂山地环境中,平坦区域由于直达声占据主导,在建筑物不同楼层间的噪声声压级改变很小;山谷区域噪声较小但有明显的混响。研究可为建设选址、建筑高度等设计问题提供建筑环境声学方面的参考。In order to study the influence of wind noise of transmission line on residential environment in the mountainous region.Using sound field simulation we analyze the wind noise of Zhourang-Tengjiao 220 kV transmission line,the results show that：in the complex mountainous environment,direct sound dominates.In f lat areas,the differences of noise level being small between building floors of different heights.In valley areas wind noise is relatively lower but with more obvious reverberation.The study can provide reference for the design issues such as site selection,building height and so on from the aspect of architectural and environmental acoustics.
