    摘要: A less costly multi-layer acoustical panel having improved noise absorption properties includes a fiberglass layer and a mineral wool layer wherein the fiberglass layer has a fibrous content comprising at least about 50% by weight of glass fiber and the mineral wool layer has a fibrous content comprising at least about 50% by weight of mineral wool fiber. The noise absorption coefficient of the panel is linearly related to increases in the thickness of the fiberglass layer. A lamination technique for making the panels is also disclosed.
