声屏障主要用于 铁路和 公路沿线，

Noise barrier is mainly used along railway and highway,

声屏障主要用于高速公路、高架复合道路、城市轻轨地铁等交通 市政设施中的隔声降噪、控制交通噪声对附近 城市区域的影响，也可用于工厂和其它噪声源的隔声降噪。

The sound barrier is mainly used for highway, combined overhead road, city light rail subway and other transportation facilities in the noise and traffic noise control of the nearby city of regional impact, but also can be used for noise reduction in factories and other noise sources.

声屏障分为纯隔声的反射型声屏障，和吸声与隔声相结合的复合型声屏障，后者是更为有效的隔声做出来的。大多数的声屏障都选用吸声和隔声混合型的产品，该型产品的特点是对道路噪声的产生和传递特征有针对性地控制。如汽车与道路摩擦声或机车与轨道摩擦声在道路下部，声音有通过屏体上部绕射的特征，所以在设计上采用上下吸声，中间隔声的结构，这样可以有效地减弱噪声的绕射；声屏障的中间使用透明的反射型隔声板，能有效地中断声波的传播途径；同时也为司机和居民提供一个开阔的视野环境。建筑声学领域，通过声学治理，控制混响时间及室内声环境，满足专业场馆要求

The sound barrier is divided into pure sound barrier reflection type sound barrier, and sound absorption and sound insulation composite sound barrier, the latter is more effective sound insulation made. Most of the sound barriers adopt sound absorption and sound insulation mixed products. The characteristics of this type of products are the control of the generation and transmission characteristics of road noise. Such as automobile and road friction sound or locomotive and track friction sound on the road through the lower part of the sound characteristics of the upper body of the diffraction screen, so the design used on sound absorption, sound insulation structure, which can effectively reduce the noise of the middle barrier diffraction; the use of the reflection type transparent sound insulation board, effectively interrupt transmission of acoustic waves; also provide a broad view of the environment for drivers and residents. In the field of architectural acoustics, the acoustic control, reverberation time and indoor sound environment are controlled to meet the requirements of professional venues
