Zusammenfassung:	A body for a vehicle, such as a pickup truck, has a passenger cabin including an exterior body panel with an air extractor aperture and an interior trim panel. The trim panel is a liner mounted to the body panel thereby defining a generally-planar laterally extending chamber between them. The trim panel, which may be made of a sound absorbing material, has an air passage fluidically coupling the chamber with the passenger cabin. The air passage is laterally separated from a footprint region of the trim panel which is aligned with the air extractor aperture. The footprint region has an undulating surface facing the air extractor aperture to attenuate noise that enters the chamber through the air extractor aperture. The undulating surface may have an egg crate shape.
