Abstract
A noise absorbing cover is provided for an automotive loudspeaker to prevent exterior noise from being coupled through a loudspeaker to the interior of the automobile. An air gap is provided around the cover to provide a vent to static pressure for the loudspeaker, thereby avoiding any degradation in low frequency performance. The air gap is oriented to exclude direct sound transmission paths for exteriorly generated noise to the interior.
