dBA stands for Diffuser Blocking Absorber, an innovative sound treatment panel for both home theaters and professional-grade commercial studios. No longer will you have to struggle to figure out noise reduction coefficients or calculate the amount of sabins for a given space.

All the guesswork will be eliminated. The new dBA panels offer sound blocking, sound absorption, and sound diffusion all in one unit. This will all be accomplished with our new tri-functional wall and ceiling panel. These sound diffuser panels have a unique design that not only provides a wide array of acoustical characteristics, but it is aesthetically pleasing and will give any studio or home theater that polished, professional look.
