Bringing down a reverberation time of over 4 secs requires lots of absorption! Using Cubes and Absorbor we fitted the rear wall and 2 side wall areas, plus a large area of ceiling to the atrium of Garth Hill School.
RPG Europe supplied all the absorbing wall panels, and provided the design, then installed the products. The RT was reduced to 1.5secs, which complies with BB93.
Photos coming soon!
