An acoustic barrier assembly including a first wall composed of a first material. The first material is substantially gas impermeable. The assembly further includes a second wall composed of a secondmaterial. The second material is substantially gas impermeable. The second wall is disposed opposite the first wall and coupled to the first wall in a manner that forms a pocket between the first walland the second wall. The assembly further includes a valve in fluid communication with the pocket. The valve is configured to be selectively opened and closed to control the passage of fluid into andout of the pocket. The valve, when closed, cooperates with the first wall and the second wall to maintain the pocket in a fluid-tight configuration. The assembly still further includes a gas disposedin the pocket. The gas has a molecular weight that is lower than the molecular weight of air.

    一种声屏障组件,包括由第一材料构成的第一壁。所述第一材料基本上是不透气的。该组件还包括由第二材料构成的第二壁。所述第二材料基本上是不透气的。所述第二壁设置成与所述第一壁相对并且以在所述第一壁和所述第二壁之间形成囊的方式与所述第一壁联接。所述组件还包括与所述囊流体连通的阀。所述阀被构造为选择性地打开和关闭,以控制流体进出所述囊的通道。所述阀在关闭时与所述第一壁和所述第二壁协作以将所述囊保持为流体密封构造。所述组件还进一步包括设置在所述囊中的气体。所述气体的分子量低于空气的分子量。
