Cac Rating Ceiling Tile

Total acoustics ceiling panels feature the ideal combination of both sound absorption nrc and sound blocking cac giving you complete noise control and design flexibility for every space.

Cac rating ceiling tile.

Best nrc cac. Total acoustics best nrc 0 80 and cac 35 noise can impede concentration healing and learning. An acoustic ceiling product with a 95 nrc rating means that 95 of sound in the room is absorbed while the other 5 is reflected. A ceiling system with a cac less than 25 is very low performance whereas a ceiling with a cac of 35 or greater is considered high performance.

The higher the cac rating the better the performance. When evaluating performance in acoustic drop ceiling tiles you ll want to reference two general ratings. Cac indicates the ceiling s ability to prevent airborne sound from traveling between adjacent rooms when the dividing wall does not connect with the structural ceiling which ranges from 0 up to 40 45 for ceiling. Noise reduction coefficient nrc and ceiling attenuation class cac.

In that case you are likely interested in a high cac. If the material is rated at 25 to 60 the sound probably passes through to the space between the ceiling tiles and the rest of the structure. Total acoustics ceilings rated best are ideal for high traffic spaces or multipurpose. Ceiling attenuation class cac is a measure for rating the performance of a ceiling system as a barrier to airborne sound transmission through a common plenum between adjacent closed spaces such as private offices and open spaces used for collaboration and focus areas.
