摘要: An acoustic panel is provided. The acoustic panel may include a hidden mounting structure formed on the rear surface of the acoustic panel. The hidden mounting structure allows the acoustic panel to be used with substrates of any density, including substrates with a medium density of greater than 2 lbs. per cubic foot (pcf) and less than 6 lbs. pcf. In one particular embodiment, the acoustic panel may be used with substrates having a density of approximately 3 lbs. pcf. The acoustic panel may also include a cover formed from two or more materials having different acoustical and/or physical properties.
