Controlling Casing Noise

Controlling Noise Casing

Terminal boxes can sometimes be located in the busy areas (corridors, toilets or machinery, equipment rooms), not more quiet areas. In quiet areas, housing noise can penetrate the ceiling and become unacceptable. Housing built around the terminal box (for example, gypsum plasterboard or sheet lead through the glass-fiber blanket, wrapped around the box) can reduce the noise to an acceptable level.

However, this method is time consuming and restricts access to the engine and volume controllers in the window. It depends on the field, satisfactory performance, dear. Limitation of static pressure in branch ducts minimizes noise casing. This method, however, limits the flexibility of terminal box systems. It is unlikely that he classifies as a control..
