Sound Performance Ratings
When evaluating acoustical properties of basement ceilings, there are two types of ratings to review: the Noise Reduction Coefficient (NRC) and the Ceiling Attenuation Class (CAC).
NRC is a rating that tells you how much sound a surface will absorb. In practical use, a ceiling NRC rating of 0.50 indicates excellent sound absorption. Compare that to drywall, which typically rates a .05
CAC rates a ceiling’s efficiency as a barrier to sound transmission. In a drop ceiling chosen for basement soundproofing, the panels prevent most sounds from passing through the ceiling and traveling upstairs. A CAC rating > 35 indicates high performance, meaning little sound is transmitted through the panels.
Soundproof Basement Ceiling Options
Smooth Look - For a clean, modern visual with noise control, 24" x 24" SAHARA tiles are a great option. If you are searching for a 24" x 48" ceiling, SAHARA Scored I & II come in that size, but look like either 12" x 12" or 2' x 2' panels.
Textured Look - If you want to add some texture, try a 24” x 24” or 24” x 48” soundproof panel with subtle visuals. You can even choose a black colored tile to complete your basement space.
Decorative White - Get sound performance with a little extra flair using 24" x 24" decorative tiles like Single Raised Panel or Fluted.
