An acoustic barrier assembly including a first wall (42) composed of a first material. The first material is substantially gas impermeable. The assembly further includes a second wall (44) composed of a second material. The second material is substantially gas impermeable. The second wall (44) is disposed opposite the first wall (42) and coupled to the first wall (42) in a manner that forms a pocket (52) between the first wall (42) and the second wall (44).The assembly further includes a valve (56) in fluid communication with the pocket (52). The valve (56) is configured to be selectively opened and closed to control the passage of fluid into and out of the pocket (52). The valve (56), when closed, cooperates with the first wall (42) and the second wall (44) maintain the pocket (52) in a fluid-tight configuration. The assembly still further includes a gas disposed in the pocket (52). The gas has a molecular weight that is lower than the molecular weight of air.
