Sound Balance acoustic board in dark grey, 1 board. For effective sound protection in your office: the acoustic board is a versatile sound absorber that will improve the room acoustics in your open-plan office. This wall panel absorbs sound and reduces the noise level and reverberation in the room, noticeably decreasing the effect of disruptive noise on everyday working life. Guaranteed effective: the acoustic board is certified as a highly efficient sound absorber that meets the requirements for sound absorption class A (calculated sound absorption coefficient αw as defined by standard DIN EN ISO 11654 = 1.0, i.e. 100% of the sound that strikes the board is absorbed). The acoustic performance has been tested and certified by Müller-BBM, an independent institute for acoustics. The acoustic board meets the highest interior design standards: the attractive trapezium-look design is an eye-catching feature for any office. There is a choice of three muted colours and three matching formats, which allow you to create a variety of combinations to cover small or large surfaces. Can also be combined with other acoustic products from the Sound Balance range, to customize your office space flexibly in line with your individual requirements. Quick and easy to mount: the board is simply attached to the wall using the pre-mounted rail on the back and the enclosed wall rail. The wall rail is screwed to the wall in the required position and then the board slides easily into place. This special system ensures a secure, sturdy hold on the wall. Practical: all acoustic boards can be used in with the SIGEL functional accessories (e.g. flipchart hooks).
