ACOUSTIC CEILING PANEL, METHOD OF MANUFACTURE AND ACOUSTIC CEILING SYSTEM
The present disclosure relates generally to acoustic panels, for example, suitable for use in a ceiling to control sound. The present disclosure relates more particularly to an acoustic ceiling panel including an acoustic substrate formed of a porous material having an air flow resistivity of at least 300 kPa*5/m2. The acoustic substrate includes an upper face and a lower face with a pattern of perforations formed therein, where the pattern of perforations covers at least 6% of the area of the lower face. The acoustic ceiling panel also includes a backing layer disposed over the upper face of the acoustic substrate and a veil disposed over the lower face.
