RPG Variscreen

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.

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.


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 "tuneable" low frequency peak to help control bass build up. 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.  

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
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

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 theatres. 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.

Applications
All critical listening rooms, including recording studios, vocal booths, home theatres, trade show exhibit rooms, quality control rooms, CD mastering, film mix and dubbing stages, and music practice rooms
