PRESSURE CONTROL IN EXTERNALLY DUCTED LOUDSPEAKERS

A vehicle audio system includes a loudspeaker configured to be acoustically coupled to an interior of a vehicle and to be ducted to an exterior of the vehicle as well as a controller coupled to the loudspeaker. The controller is configured to (i) detect one or more vehicle operating parameters of the vehicle that would result in a pressure differential condition between the interior and the exterior, and (ii) adjust a gain of an audio signal provided to the loudspeaker in response to detecting the vehicle operating parameters
