Overview

The Diffractal provides full spectrum sound diffusion in a single integrated diffuser. To achieve this, the self similarity property of fractals was combined with the uniform scattering property of a quadratic sound diffuser. This unique and patented design expands the bandwidth and offers the broadest spectrum of sound diffusion available.

Finish

The Diffractal comes in a wide variety of finishes, including wood veneer, laminates, melamine coatings and painted surfaces. See some of the options displayed under the Finishes tab below.

Installation

The Diffractal can be mounted on wall or ceiling surfaces by attachment to a provided wooden cleat. Due to it’s 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. See details below under the Drawings tab.

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.
