a sound - absorbing shield device for use in a vehicle door comprises a sheet of sound - absorbing material and a thin sheet of polymer film . a first face of the polymer film is attached to the sound absorbing material and a plurality of apertures extending through the polymer film from the first face thereof to a second face thereof opposite the first face . each aperture is bounded by a hollow protrusion extending from the second film face , whereby the apertures and protrusions cooperate to form a barrier against moisture or other environmental contamination while admitting acoustic energy therethrough into the sound absorbing material .
