Repetitive reflections from hard parallel surfaces produce flutter echoes that are perceived as timbre coloration and degrade sound quality and speech intelligibility. Absorptive surfaces are often used to control this annoying problem, with the unfortunate side effect of making the room too 'dead'.
FlutterFree® is the first acoustical hardwood moulding that controls flutter echo by diffusion, maintaining the natural ambiance of the room. When adjacent panels are spaced and mounted with an air cavity, low frequency absorption can also be achieved.
Absorptive fabric wrapped panels are the traditional treatment for flutter echoes which are caused by repetitive reflections between hard parallel walls. While absorption reduces flutter echoes, it also produces an acoustically 'dead' space. The resulting lack of ambiance makes the room seem psychoacoustically smaller and reduces the support of acoustic speech levels which makes conversation difficult.
FlutterFree® is a handsome, furniture grade, acoustical hardwood moulding that provides flutter echo control as well as bass absorption. Its application converts small rooms with flat parallel surfaces into functional spaces with good speech intelligibility, sound quality, and a natural, comfortable ambiance. It expands the designer's flutter control finish treatment options beyond fabric upholstered surfaces.
Offers mid-high frequency diffusion, with the possibility of low frequency absorption using a Helmholtz mount
Offers mid-high frequency diffusion with accompanying absorption below the diffusion cut off. Additional low frequency absorption may be added using a Helmholtz mount
