Abstract: An acoustic decorative sheet includes a film layer, a glass cloth layer, and an adhesive layer separating the film layer from the glass cloth layer. The adhesive layer is adhered to the film layer and the glass cloth layer. The film layer and the adhesive layer have a plurality of micro bores disposed there through. The micro bores have a diameter in a range from 20 to 500 micrometers and number from 2 to 700 microbores per cm2. An acoustic assembly includes the acoustic decorative sheet, a substrate; and an air gap at least partially separating the acoustic decorative sheet from the substrate.
