Ceiling Attenuation Class (CAC)
CAC can be applicable between adjacent rooms and between rooms and a corridor.
Ceiling Attenuation Class 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.
CAC can be applicable between adjacent rooms and between rooms and a corridor. Higher values provide more insulation.
CAC is measured in decibels according to the ASTM E1414 standard.
Rockfon® Sonar dB™ provides a CAC value up to 43 dB while maintaining good sound absorption (NRC = 0.85)
