Product Testing & Information

dBA stands for Diffuser Blocking Absorber. Our dBA panels are available in 1″ and 2″ thickness. Panel size is 2′ × 2′. The dBA sound diffuser panel is intended for wall or ceiling applications. The dBA sound blocking panel is 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. As it stands, the new dBA sound blocking panels will come in white or charcoal only, but as the line expands so will the color choices. Keep in mind these sound diffuser panels can be painted to match any decor. (ask for acoustical painting instructions)
