HARMONI Ceiling Tiles are made from illbruck's willtec[R] foam, making them lightweight and easy to install. In addition, HARMONI tiles have a Noise Reduction Coefficient The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption. (NRC NRC abbr. 1. National Research Council 2. Nuclear Regulatory Commission Noun 1. NRC - an independent federal agency created in 1974 to license and regulate nuclear power plants ) of 0.90, meaning they are able to absorb 90% of the sound that reaches them for maximum sound absorption Sound absorption The process by which the intensity of sound is diminished by the conversion of the energy of the sound wave into heat. The absorption of sound is an important case of sound attenuation. across a broad range of frequencies. The tiles are mold resistant, Class 1 fire-rated, and coated in Hypolan[R] to optimize durability, prevent dirt and dust penetration, and make cleaning easy.
