ABSTRACT:
A branch take-off and silencer apparatus for an air distribution system. The apparatus couples an input duct to one or more branch ducts and to a coaxial output duct having a similar but smaller cross-section than the input duct. Coaxial extensions of the input and output ducts define a shell region. The shell region is closed at its downstream end and open at its upstream end to oncoming air in the input duct. The shell region is divided at that upstream end by porous acoustical material into a plurality of adjacent channels which lead to a plenum near the downstream end of the shell region. The plenum is coupled to the branch ducts.
