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 best nrc 0 80 and cac 35 noise can impede concentration healing and learning. 
																	Noise reduction coefficient nrc and ceiling attenuation class cac. 
																	In that case you are likely interested in a high cac. 
																	Best nrc cac. 
															
													
									
	
		
	
																	When using a high cac ceiling wall construction with a minimum stc 40 rating should be specified. 
																	The higher the cac rating the better the performance. 
																	Nrc and cac ratings. 
																	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. 
															
													
									
	
		
	
																	When evaluating performance in acoustic drop ceiling tiles you ll want to reference two general ratings. 
																	Total acoustics ceilings rated best are ideal for high traffic spaces or multipurpose. 
																	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. 
																	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.
