Abstract: The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a nonwoven facing and to methods for making such panels. One aspect of the disclosure is a method for preparing an acoustic panel comprising providing a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The method includes disposing directly against the outward major surface of the base structure a sprayable mixture comprising a plurality of fibers, one or more binders, and a dispersive medium. The method includes drying the disposed mixture to provide a facing layer disposed on the outward major surface of the base structure, the facing layer having an exterior major surface opposing the outward major surface of the base structure.

Abstract: The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a porous facing and to methods for making such panels. One aspect of the disclosure is an acoustic panel comprising a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The panel includes a coating layer directly disposed on the outward major surface of the base structure, the coating layer being formed of an open-cell foam. The coating layer has an exterior major surface opposing the outward major surface of the base structure. The coating layer is substantially scattering for light in the wavelength range of 380 nm to 780 nm, and has an absorption coefficient of less than 0.5 for acoustic frequencies in the range of 100 Hz to 10,000 Hz.
