RPG omniffuser diffuser RPG omniffuser diffuser

  • Conventional acoustic treatments have relied on absorption for reflection control. Unfortunately, this can “deaden” the room and make it unsuitable for speech or music.

  • Diffusive ceilings and walls are one of the most effective ways to simultaneously control room reflections and provide a natural ambiance.



  • Since ceiling systems and wall applications often cover appreciable surface areas, a cost-effective 2D diffusor is required.



  • To meet these needs and life safety fire codes, the non-combustible Fiber Reinforced Gypsum (FRG) modular 2D diffusor that tegularly mounts in a standard T-bar system was designed.



  • The FRG Omniffusor uniformly scatters sound arriving from any direction into many directions, providing ideal distribution and coverage. It’s unique shape also adds the visual interest of a bas relief sculpture.

    Problem and Solution

    Problem
    To provide 2D diffusion for large surface areas and meet life safety fire codes, a molded modular diffusor that mounts in conventional T-bar systems is needed.

    Solution
    The FRG Omniffusor is the first cost-effective, non-combustible, molded Fiber Reinforced Gypsum 2D QRD. It offers twice the reflection attenuation of the 1D QRD because it scatters sound uniformly into a hemisphere. The FRG Omniffusor provides uniform, omnidirectional, broad bandwidth diffusion in an attractive ceiling or wall design element.

    Absorption
    While the primary function of the FRG Omniffusor is to provide broad bandwidth diffusion, it also offers a modest and beneficial amount of absorption across the frequency spectrum with a small emphasis at about 800Hz.

    FRG Omniffusor Diffusion Graph

    Diffusion
    The FRG Omniffusor offers significant diffusion compared to a flat reflector panel above the diffraction limit of 565 Hz, which is determined by the dimensions of the panel. Above this frequency, the graph indicates how the reference reflector becomes more and more specular as the frequency increases, whereas the FRG Omniffusor provides a constant diffusivity.

    Installation

    FRG Liteffusor

    When suspended in a 15/16" T-bar grid, the FRG Omniffusor and FRG Liteffusor protrude 3 1/4" into the room. Wall mounting the FRG Omniffusor requires custom wooden stiles and rails with a 1/8" dado to capture the perimeter flange.
