It is well-known that a wall or heavy enclosure can serve as a very effective barrier against airborne sound transmission. While any surface will reflect some of the sound which reaches it, only heavy, acoustically designed materials and systems with airtight surfaces are significantly effective in “stopping” sound. The effectiveness of a barrier depends on the weight, stiffness, mounting, damping, the use of single or multiple panels, the spacing of these panels, and the use of absorptive material in the cavities.
