FlutterFree-T is an attractive, furniture grade acoustical wood plank designed for mid-high frequency sound diffusion. To achieve mid-band diffusion, RPG optimized an asymmetric well structure to reduce periodicity effects when installed properly.
FlutterFree-T is available in hardwoods, softwoods and painted finishes. RPG offers factory color matching on both wood finishes and paint colors. See some of the options displayed under the Finishes tab below.
FlutterFree-T is best mounted perpendicular to wood battens for wall or ceiling mounting. Batten spacing should be no more than 16″ on center. The mounting can be configured to integrate both mid and low frequency absorption to further enhance the acoustical attributes for more demanding applications. See details below under the Drawings tab.

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, which provides the best performance available today. In addition, the “T” well innovation at each plank junction offers lower frequency diffusion performance than is otherwise possible in such a shallow depth. Its durability and broad selection of finishes make it a logical choice for worship spaces, recording studios, music education facilities, auditoriums and performing arts facilities. FlutterFree® is available in a wide variety of finishes, including natural hard and soft woods, stains and painted finishes to match any manufacturer color code. It can be mounted to virtually any surface and can be configured to offer low frequency absorption.
FlutterFree-T is the first computer optimized sound diffusing plank in the world that supports the advanced concept of optimally modulating aperiodic, asymmetric shapes for the best performance possible. 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.
