Noise Control

In the Built Environment
By far the easiest and most economical method for controlling noise is to install insulation in the wall cavity. Fiber glass insulation is an excellent sound absorber as well as an energy saver. When installed in the walls and ceilings, it can reduce the transmission of sound from other rooms or from the outside.
Adding insulation beneath drywall in a typical wall configuration can reduce sound transmission significantly. If a new wall is being constructed, homeowners can also build what is called a resilient channel between the drywall and the studs or joists. Properly installed resilient channels will break the noise vibration path, providing a dramatic reduction in sound transmission.
In HVAC Systems
Without fiber glass insulation products, the acoustical environment of mechanically conditioned buildings can be greatly compromised. Fiber glass insulation greatly reduces the transmission of HVAC equipment- and air flow-generated noise through the duct system, and also reduces cross-talk from one room to another through the ducts.
