CIRRUS Second Look

NRC (Noise Reduction Coefficient) is a standard measurement for a material’s acoustical absorption ranging from 0.00 (no absorption) to 1.00 (total absorption).

CAC (Ceiling Attenuation Class) is a standard measurement of a ceiling system’s ability to block sound between two closed spaces. CAC values of 35 or greater are recommended to achieve speech privacy.

NIC (Noise Isolation Class) is a standard measurement of total sound attenuation between two closed spaces. It considers the ceiling, wall, and other interior finishes.

AC (Articulation Class) is a standard measurement of a ceiling system’s ability to attenuate sound within a large open plan space. AC values of 170 or more are recommended to reduce speech distraction.

Sabin is the unit of measure for total sound absorption of an acoustical object (like blades, baffles, clouds, and canopies).

Now, standard products available in 4 weeks or less provide a variety of options and offer short lead times to fit most budgets. Standard sizes and colors mean no shop drawings or submittal sample approvals. Package with the diverse portfolio of Armstrong solutions.

Acoustics

Acoustical options available.
 
  Sound Absorption (NRC)

A measure for rating the overall sound absorption of a material when used in an enclosed architectural space where sound is reflected at many angles of incidence. A ceiling system with an NRC < 0.50 is low performance, an NRC > 0.70 is high performance.
0.65
  Sound Blocking (CAC)

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. A ceiling system with a CAC < 25 is considered low performance, whereas one with CAC of 35 or higher is high performance.
