RPG FlutterFree - Sound Diffuser Plank

Flutterfree and Flutterfree T are furniture-grade acoustical wood planks designed for high-frequency sound diffusion.

FlutterFree 1D Wood Sound Diffusing Plank 

The phase grating surface of the Flutterfree is designed to provide a more uniform ambient sound field through high frequency diffusion while the solid wood construction of the unit limits the amount of sound energy that is removed by absorption.

Rather than remove the high frequency energy that strikes key surfaces in a space, Flutterfree preserves that energy by uniformly distributing it back into the space. The onset of significant diffusion for Flutterfree occurs at approximately 4000 Hz.

FlutterFree-T 1D Optimized Wood Sound Diffusing Plank

The phase grating surface of the FlutterFree-T is designed to provide maximum uniformity for the ambient sound field through high frequency diffusion while the solid wood construction of the unit limits the amount of sound energy that is removed by absorption. The computer optimized, asymmetric pattern of wells provides the basis for being able to optimize an array of planks in an aperiodic fashion. In addition, the ‘T’ well at each plank junction offers lower frequency diffusion performance than is otherwise possible in such a shallow depth.

Rather than remove the energy that strikes key surfaces in a space, FlutterFree-T preserves the energy by uniformly distributing the energy back into the space. The onset of significant diffusion for FlutterFree-T occurs at approximately 2000 Hz.

FlutterFree is available in a wide variety of finishes, including natural hard and soft woods, stains and painted finishes to match any manufacturer colour code. It can be mounted to virtually any surface and can be configured to offer low frequency absorption.

FlutterFree and FlutterFree T are best mounted perpendicular to wood battens for wall or ceiling mounting. Batten spacing should be no more than 400 mm on centre. The mounting can be configured to integrate both mid and low frequency absorption to further enhance the acoustical attributes for more demanding applications.
