Abstract
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 exceed about 100 MKS rayls. The air flow resistance of the front layer lies in the range of about 300 to about 800 MKS rayls. The air flow resistance of the rear layer lies in the range of about 300 to about 1200 MKS rayls. The panel would be supported on a grid suspended below a structural ceiling to form an air space therebetween.
