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.

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.
