Without sound absorbing materials in a room, sound simply bounces around from one surface to the next, resulting in reverberation – or what we all perceive as noise.
That noise can be a mixture of voices, printers, phones ringing, air conditioners – all bouncing around together resulting in an unnecessary and uncomfortable distraction for those trying their best to work, learn or heal in the space.
If you have a busy open plan, its best to choose a ceiling tile with a high NRC (acoustic absorption) rating. We recommend an NRC rating of 0.70 to 0.90 depending on how many hard surfaces (such as hard flooring) and people are in the space.
If there are closed rooms, then a ceiling tile designed to both absorb sound & prevent it traveling to the adjacent area is recommended.
That’s where CAC comes into play.
If you have a closed office environment, we recommend choosing a ceiling that offers:
Example: A higher CAC of 40 or more might be required where there is a boardroom next to a kitchen/lunchroom where people congregate.
