高速公路声屏障安装的常见地点
Common Locations for Installation of Highway Noise Barrier
虽然一般高速公路都是在城市外围铺设，但是随着城镇化建设越来越集中，城市外扩，很多小区建设距离高速公路的距离也很近，所以就需要加装声屏障。一般小区周围安装的是透明声屏障，起到隔声作用，也不阻挡视线和采光。
Although expressways are generally laid on the outskirts of cities, with the increasing concentration of urbanization and expansion of cities, many residential areas are close to expressways, so it is necessary to install sound barriers. In general, transparent noise barriers are installed around the residential area, which play a sound insulation role, and do not block sight and lighting.
在村庄周围安装的是金属百叶孔声屏障和透明声屏障居多，村庄是高速公路经过最多的可以说是。
Around the villages are mostly metal shutters and transparent noise barriers, which can be said to be the largest number of villages passing through the expressway.
如果高速公路两边有非常容易分散司机、驾驶员注意力的景象和场所等，也会设置声屏障。一般常用金属微孔或是百叶孔居多。
If there are scenes and places on both sides of the expressway which are very easy to distract drivers and drivers, noise barriers will also be set up. Metal micropore or louver are commonly used.
经过动物保护区时，这种情况一般是安装全封闭声屏障，像候鸟聚集地，不能因为车辆行驶对动物造成影响。
When passing through the animal reserve, this situation usually involves the installation of a fully enclosed sound barrier, such as a migratory bird gathering area, which can not be affected by vehicles.
