RPG® has utilized its patented “Aperiodic Modulation of a
Single Asymmetric Optimized Base Shape” technique to produce a new optimized, asymmetric
FlutterFree®-T, which features a folded well configuration at the junction of two planks. The diffusion bandwidth is greatly improved over the traditional FlutterFree® that uses a number theoretic design.
FlutterFree®-T is a handsome, furniture grade, acoustical hardwood molding
that provides flutter echo control. Its application
converts 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.
Absorption
 When FlutterFree®-T panels are mounted 1/16" apart, the graph at left can be used
to determine the spacing from the mounting wall for the desired absorption
frequency. For example, to achieve bass absorption at 100 Hz, follow the
vertical 100 Hz frequency line until it intersects the leftward sloping
fractional open area line. Follow the horizontal line to the 8" intersection
point.
Diffusion
 The image at left illustrates the
FlutterFree®-T in an aperiodic modulation arrangement. The
orientation of adjacent FlutterFree®-T planks
follows the prescription of an optimal binary
sequence. The "T" well configuration in conjunction with RPG's patented “Aperiodic Modulation of a
Single Asymmetric Optimized Base Shape” technique is what gives the FlutterFree®-T its greatly improved performance over the original FlutterFree®.
Installation
FlutterFree®-T is molded on a 5 head wood molder from hardwood that is kiln dried to 6-8% moisture content.
RPG® takes every precaution to minimize warping by stress relieving the rear surface and treating all exposed
surfaces on prefinished orders. FlutterFree®-T can either be nailed or glued directly to a wall surface or laterally
spaced and mounted with a rear air cavity for low frequency absorption. In this Helmholtz mounting, a semi rigid
fiberglass panel is mounted directly behind the FlutterFree®-T, where the particle velocity is a maximum , as
opposed to on the rear wall. When used as wall panels, a hardwood frame (not supplied) is suggested.

FlutterFree®-T
The First Digitally Optimized Sound Diffusive Hardwood Molding From The Acoustical Industry’s Leading Innovator
| Features
& Benefits |
Features
Furniture grade, hardwood, sound diffusing acoustical molding
Low frequency absorption mounting option
FlutterFree®-T works on the “Aperiodic Modulation of a Single Asymmetric Optimized Base Shape” technique
Modular extruded diffusive strips
Benefits
Handsome furniture grade hardwood finish offers specifiers a
new approach to flutter echo control that does not rely on the
use of fabric upholstered fiberglass panels
Offers an almost unlimited variety of lacquered, stained, or
painted finishes and hardwood options
Diffusive flutter control minimizes flutter echoes without making
the space acoustically ®dead”
Diffusive flutter control provides an ambient environment to
support speech in conference rooms for less fatigue, greater
coverage, and high speech intelligibility
Mounting FlutterFree®-T over an air cavity provides low frequency
absorption to minimize boominess and lack of definition in small
rooms
