Problem and Solution
There is a need for a free-standing variable acoustic screen that can provide broad bandwidth absorption, diffusion with absorption, and bass control.
The VariScreen offers absorption on one side, diffusion and absorption on the other, and a Variable Depth Air Cavity formed by its two hinged upholstered panels for variable frequency bass control
(Please note: castors add another 60mm to the height)
Performance - Absorption
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 74ft² 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 74ft², 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.
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.
The VariScreen has proved to be 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.
The Variscreen can also be supplied with flat stainless steel feet if required.
As an alternative option we can also manufacture these units with a metal surround for more arduous / industrial applications. The framework protects the edges of the unit from knocks and bashes (see picture on the left).
