Many things can be dampened including walls, ceilings, floors, pipes, sheet metal, doors, isolation boxes, basically anything with low mass that will vibrate from sound transfer. Most damping between layers of drywall or wood is accomplished with a damping compound such as Green Glue Compound. While our VibraDamp will dampen lightweight plastic or metal surfaces including pipes, sheet metal, and the inside of automobiles. The concept of damping is to convert sound vibrations to non-perceptible amounts of heat.
Damping will help isolate across all frequencies with the most significant gains in the mid to high frequency range. When applied to the floor or ceiling, damping will also help with isolating impact footfall sound transfer, assuming the assembly is resilient, i.e. resilient clips, resilient channel, or independent joists.
