An acoustic barrier assembly includes a first wall that is gas impermeable. The acoustic barrier assembly further includes a second wall that is gas impermeable. The second wall is disposed opposite the first wall. The acoustic barrier assembly further includes a periphery wall coupling the first wall with the second wall in a manner that forms a pocket between the first wall and the second wall. The periphery wall is flexible, and the pocket is fluid-tight. The acoustic barrier assembly further includes a gas disposed in the pocket. The gas has a first molecular weight that is lower than a second molecular weight of air. The acoustic barrier assembly still further includes a biasing member that is disposed within the pocket. The biasing member is coupled with both the first wall and the second wall.
