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 second material. 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 wall and 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 and out 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 disposed in the pocket. The gas has a molecular weight that is lower than the molecular weight of air.
