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. It has become a classic shape in architectural acoustics; from its beginnings over 20 years ago it can now be found in church, theater and recording studio spaces all over the world. Its durability and broad selection of finishes also make it a logical choice for 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.
Interfering reflections that degrade sound quality can be controlled by absorption and/or diffusion. When absorption alone is used to control reflections it creates "dead" sounding spaces that lack the benefit of late order reflections which can greatly enhance the acoustic performance of a space.
FlutterFree® is the first and most applied sound diffusing plank in the world. 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.
