Abstract
A device for reducing sound from an air treatment unit includes, in one embodiment, a wall curb. The air treatment system includes a supply opening and a return opening. The wall curb includes a frame portion defining an interior chamber. A partition divides the interior chamber into a supply plenum in a first portion of the interior chamber and a return plenum in a second portion of the interior chamber. A curb supply opening is formed through the perimeter frame in communication with the supply plenum. A curb return opening is formed through the perimeter frame in communication with the return plenum. The curb return opening is positioned such that airflow through the return plenum is non-linear and a sound absorbing material may be positioned on at least some inside surfaces of the return plenum.
