Abstract
An air-cooled enclosure of an information handling system includes a chassis that receives at least one heat-generating functional component. One or more air movers are positioned within the chassis to move cooling air through the chassis. An air duct is provided within the chassis and is positioned to direct the cooling air between the one or more air movers and the at least one heat-generating functional component. The air duct has a transverse space across the air duct sized for one or more acoustic standing waves to resonate between lateral walls of the air duct as modes of a resonant wavelength. One or more vertical blocks of an acoustic absorbing material are attached inside the air duct at respective transverse positions of one or more pressure or velocity antinodes of a selected one or more modes of the resonant wavelength.
