What is CAC? Ceiling Attenuation Class is a measure for rating the efficiency of a ceiling system as a barrier to airborne sound transmission between adjacent closed spaces that share a common air plenum. The higher the CAC rating, the better the performance.
What is the difference between CAC and NRC?
A ceiling system with an NRC < 0.50 is low performance, an NRC > 0.70 is high performance. NRC is important in any space where reverberation time and noise levels are an issue. … A ceiling system with a CAC < 25 is considered low performance, whereas one with CAC of 35 or higher is high performance.
