Cac Rating Ceiling Tile

Total acoustics best nrc 0 80 and cac 35 noise can impede concentration healing and learning.

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. When evaluating performance in acoustic drop ceiling tiles you ll want to reference two general ratings. Nrc and cac 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.

In that case you are likely interested in a high cac. 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. Nrc tells you how much sound a ceiling panel will absorb thereby lessening the noise within a room. Noise reduction coefficient nrc and ceiling attenuation class cac.

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. Total acoustics ceilings rated best are ideal for high traffic spaces or multipurpose. When using a high cac ceiling wall construction with a minimum stc 40 rating should be specified. 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.
