    摘要: An acoustic ceiling panel for a lay-in or suspended ceiling includes a core portion, and front and rear layers covering front and rear sides, respectively, of the core portion. The air flow resistance of the core portion does not exbeed about 100 MKS rayls. The air flow resistance of the front layer lies in the range of about 300 to about 800 MKS raylt The air flow resistance of the rear layer lies in the range of about 300 to about 1200 MXS rayls. The panel would be supported on a grid suspended belbw a structural ceiling to form an air space therebetweeu.
