金属穿孔声屏障运用于城市轻轨、高架道路、动力设备、机械设备、铁道、公路、桥梁、隧道、航空、航海、高架公路等场合的吸声结构。金属穿孔声屏障板在道路交通声屏障、城市轨道声屏障、高铁声屏障等声屏障工程中常用来作为吸声屏体的面板，通常朝向声源一侧，用于吸收声源，避免声屏障屏体与车身之间的相互反射而增大噪声。

The metal perforated sound barrier is applied to the sound absorption structure of urban light rail, elevated roads, power equipment, machinery and equipment, railways, highways, bridges, tunnels, aviation, navigation and elevated highways. Perforated metal plate sound barrier in the road traffic noise barrier, city rail noise barrier and high barrier Tiesheng sound barrier engineering is often used as the sound absorption screen panel, usually toward the side of the sound source, to absorb the sound source, to avoid the mutual reflection between the sound barrier body and body increased noise.
