A finished basement gives your family a gathering space for so many fun activities – game room, home theater, gym or simply
a place to hang out with friends after school. The problem with activity-designated rooms is that they can be noisy! You can
reduce a lot of unwanted sound with soundproof ceiling tiles and planks. Not only do they help reduce noise but their decorative
features will transform a room with a stylish new look.
Soundproof ceilings work by absorbing sound waves that bounce around within a room. Some can absorb up to 70 percent of the
sound that strikes their surface, creating a comfortable environment free of harsh noise and echoes. They can also prevent
noise from traveling to nearby rooms. When shopping for a soundproof ceiling, there are 2 important ratings to look for. They’ll
tell you how effective the ceiling will be in sound control.
Sound reduction – The Noise Reduction Coefficient (NRC) rating tells you how much sound a ceiling tile or panel absorbs. For ceilings with
great sound reduction, look for an NRC rating around .50 (or higher). That means the ceiling will absorb 50% of the sound in a room. By comparison,
a typical drywall ceiling with a NRC of .05 will only absorbs 5% of sound.
Sound blocking – Sound can be disruptive when it travels to nearby rooms. You can correct this problem with sound blocking ceilings. This type of acoustical ceiling has a Ceiling Attenuation Class (CAC) rating to tell you how effective it is at blocking
sound from traveling to adjacent rooms or to the floor above. A CAC rating of 30 or greater indicates high performance, meaning
the ceiling will block 30% of sounds that strike its surface.
Combination soundproofing – For the most effective sound control, choose a ceiling product that combines both the NRC and CAC ratings.
All Armstrong ceiling tiles, panels and planks have an acoustical rating listed in the Performance Details section of the Specifications tab.
