An auxiliary power unit inlet assembly includes an inlet duct having a first end and a second end. The auxiliary power unit inlet assembly further includes a door associated with the second end of the inlet duct. The door moves between a first position and a second position. The door closes the second end of the inlet duct when in the first position and permits air to enter the second end of the inlet duct when in the second position. The auxiliary power unit inlet assembly further includes a sound absorbing component mounted to the door and disposed proximate the inlet duct. The sound absorbing component is positioned at a location on the door such that a noise generated by the auxiliary power unit will directly impinge on the sound absorbing component.
