Typically, duct silencers are provided at or near the penetrations to maintain the STC ratings of the walls and ceilings. This study looks at factors related to the optimum location of duct silencers between spaces requiring sound-rated constructions. The constructions studied are based on the actual constructions used in the CBC Broadcast Centre in Toronto}, number={4}, journal={Canadian Acoustics}, author={WuM.Q. and PaigeT. and AllenD.L.}, year={1991}, month={Sep.}, pages={13-13} }
