PIPING AND DUCTWORK ACOUSTICAL LAGGING
Noise radiating from piping and ductwork can be a serious problem in modern
building construction. Turbulent flow piping noise can be caused by water or other
liquids passing through elbows, valves or other transition pieces. Duct noise is
caused by air flowing past obstructions or branches which results in the vibration of
the metal ductwork. This vibration then radiates noise into the building.
