Definitions:

NRC - Noise Reduction Coefficient is a single-number rating that expresses the degree to which a ceiling panel absorbs sound. NRC is represented by a number between 0 and 1.00, which indicated the percentageof sound reaching the panel that will be absorbed. A ceiling panel with an NRC of .50 or higher offers significant sound-absorbing properties.

CAC - Ceiling Attenuation Class indicates the ability of a ceiling panel to block sound transmission between adjacent rooms through a ceiling plenum. A ceiling panel with a CAC of 35 or higher offers significant sound attenuation properties.

LR - A high light reflectance ceiling makes lighting systems, especially indirect lighting, more effective, while further reducing energy cost and occupant eystrain.
