Problem and Solution
|
|
Problem
Specular reflections from flat, hard surfaces cause strong reflections
that corrupt speech intelligibility and degrade music quality. Typically, fabric wrapped absorptive
panels are used to control interfering reflections, with the undesirable side effect of deadening the
space.
Solution The Omniffusor is the first 2D QRD. It offers twice
the reflection attenuation of the 1D QRD, because it scatters sound uniformly into a
hemisphere. The Omniffusor provides uniform, omnidirectional, broad bandwidth diffusion in an
attractive ceiling or wall design element.

Absorption
While the primary function of the 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.
|

|
|
Diffusion
The 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 Omniffusor provides a constant diffusivity.

Installation
|
 |
|
Wooden Omniffusors can be wall mounted. For wall installation, plexiglass Omniffusors should be flush
mounted into a framed opening. Decorative trim can be added to conceal the perimeter joint.

FEATURES
- 2D QRD provides twice the diffusive specular attenuation of a 1D QRD
- The 2D QRD provides phase variation in two orthogonal directions for uniform
omnidirectional scattering
- Hemispherical scattering makes the Omniffusor ideal for ceiling applications because
the incident sound is uniformly distributed throughout the room from a planar ceiling surface
- The omnidirectional diffusive attenuation, coupled with moderate mid band absorption,
provides ideal reflection control without deadening the space
- The wide range of wood finishes makes the
Omniffusor an attractive architectural addition to a space
- Modular 2" x 2" panels can be wall mounted or suspended in a 15/16" heavy duty T-bar ceiling grid
