Sound Balance acoustic edge in dark grey, 1 piece. Absorbs sound, optimising the acoustics in open-plan offices. The acoustic edge can be mounted horizontally or vertically in the 90° edges of a room. When positioned in places that are sensitive to acoustics, the acoustic edge acts as a highly effective sound absorber. It absorbs up to 80% more sound in the relevant frequency than a two-dimensional sound absorber. Its effectiveness has been tested and certified by Müller-BBM, an independent institution for acoustic assessment. Simple to affix to the wall by means of the pre-mounted board rail and wall rail, enclosed in the pack. The wall rail is drilled into place and the acoustic edge then simply slides onto it and clicks into place. This special rail system ensures a secure hold on the wall. The acoustic edge is 800x150x150 mm in size. Other sizes and colours are available and are simple to combine with this element.
