The
VariScreen™ is the industry’s first free standing variable acoustics
screen with a broad bandwidth absorbor on one side and RPG®’s
flat binary amplitude diffsorbor (BAD™)
on the other. This hinged upholstered panel can be positioned and adjusted
with a Variable Depth Air Cavity (VDAC™) to control low frequency
modal problems. The VariScreen™ is designed for difficult to treat
rooms in which surface application is not possible and flexibility is
paramount. Acoustically problematic trade
show demo rooms are easily tamed with the VariScreen™ as well
as almost any critical listening space.
Problem
There is a need for a free standing variable acoustics screen that can
provide broad bandwidth absorption, diffusion with absorption, and bass
control.
Solution
The VariScreen™ offers absorption on one side, diffsorption on the
other, and a Variable Depth Air Cavity (VDAC™) formed by its two
hinged upholstered panels for bass control.
Performance
 The
graph illustrates the total absorption, in Sabines, for each VariScreen™
mounted along a wall with the height of the triangle being 16''. Three
panels covering 74 square feet with the absorption side facing the room
were used for the test. The absorption coefficient, which is equal to
three times the number of Sabines divided by 74ft squared, is also shown.
The VariScreen™’s NRC is 1.2. 
Note the uniform mid and high frequency absorption with a "tunable" low
frequency peak to help control bass buildup. By adjusting the position,
distance from the wall, and the Variable Depth Air Cavity, the VariScreen™
can be used to control even the most problematic rooms.
Installation
The VariScreen™ is a hinged, free standing panel which supports itself
by adjusting the panel opening angle. By making the angle smaller and
increasing the depth of the air cavity, more low frequency absorption
can be obtained. Corner mounting is also very effective for low frequency
control. When not in use, the VariScreen™ stores flat.
RPG has found that the VariScreen™ is an invaluable tool in home
theaters. The rear air cavity is very powerful in tailoring the room's
bass response. The VariScreens™ can be used as free-standing screens
in front of windows, in corners, or as room dividers. To allow it to act
as a sound isolation barrier, the option of a mass loaded vinyl barrier
in the middle of the VariScreen™ is being offered. This feature is
useful when there is no rear wall in a room and partial sound isolation
is desired. Optional ball casters are available to ease mobility.
 In
addition, Skylines® may be mounted
to the VariScreen™ for added diffusion.

| Features
& Benefits |
Features
Two sided absorptive or diffsorptive performance
Variable Depth Air Cavity (VDAC™)
Free standing screen
Stores flat
Modular and versatile
Design element
Ball casters to ease mobility are available
Benefits
The VariScreen™ is a two sided, hinged acoustical treatment
offering pure absorption or a combination of high frequency
diffusion and mid frequency absorption (diffsorption) for reflection
control with ambiance
The hinged free standing screen allows adjustment of the opening
angle to tune the room’s low frequency response
Since the VariScreen™ is free standing, it can be used
in applications that require temporary treatment like trade
show exhibit rooms or where wall mounting is not possible
Also supports Skyline®
2D diffusors when additional diffusion is required
The VariScreen™ covers up to 32 square feet when in use,
but stores flat in a minimum of space for economical shipping
and storage
The VariScreen™ is modular, which allows almost any type
of space to be treated by simply placing units next to one another
for unlimited versatility and flexibility
By utilizing a wide range of designer fabrics, the VariScreen™
offers an aesthetic design element as well as a flexible acoustical
element |
