Abstract
An acoustic attenuator includes an intake air duct having an intake air duct opening leading to an outside environment and a blower fan opening leading to a blower fan. Air is drawn through the intake air duct opening towards the blower fan and a primary reflecting panel disposed in the intake air duct. The primary reflecting panel is configured to reflect sound propagated from the blower fan away from the intake air duct opening.
