Diffractal® 1D Nested Wood Sound Diffuser 
In an effort to provide full spectrum sound diffusion in a single, integrated sound diffusing panel system, the self-similarity property of fractals was combined with the uniform scattering property of a number theoretic reflection phase grating to produce the Diffractal®. This unique and patented acoustical design expands the bandwidth of its predecessor, the QRD® 734, and offers the broadest spectrum of sound diffusion available. The Diffractal® comes in a wide variety of finishes, including wood veneer, laminates, melamine coatings and painted surfaces. It can be mounted on wall or ceiling surfaces by attachment to a provided wooden cleat. Due to its depth, it is often recessed into a wall or ceiling cavity. The standard unit size also allows for it to lay into a standard, reinforced T-Bar ceiling grid.

Problem
The bandwidth of diffusion demanded by a sound quality critical space such as a concert hall, recording control room, mastering room and high fidelity listening environment is beyond what most sound diffusing products are capable of delivering.

Solution
The Diffractal® is the first sound diffusing panel that utilizes a fractal design philosophy. It consists of nested self similar scaled diffusers, each of which covers a specific frequency range and offers wide area coverage without lobing effects. The Diffractal® contains two nested QRD® type sound diffusing elements, thus forming a diffuser within a diffuser. Each diffuser provides uniform scattering over a specific range of frequencies so that the effective bandwidth is extended. The Diffractal® can be further customized to extend into lower frequencies by either perforating the wells to add low frequency absorption, or by nesting the unit into a larger cabinet that is a larger scale version of the unit.
