Abstract (en)
[origin: US2006272888A1] An air intake silencer assembly at the intake of an air handling system includes a plenum housing having an inlet end for receiving air and having an outlet port for discharging air. Two baffle panels in spaced relation in the housing define, with the housing, an inlet chamber, a central chamber, and a discharge chamber. A plurality of tubular members is supported by the baffle panels and each includes a perforated core and a sound dissipating fiber wrapping. Air flows into the inlet chamber, through the plurality of tubular members to the discharge chamber, and is discharged from the discharge chamber through the outlet port.
