In addition to an extensive facelift of the interior facades, new lighting and seating, the room acoustics in particular was significantly improved. For this purpose, the previous 8-ton wooden ceiling above the orchestra room was removed and replaced with 10 individually suspended and individually adjustable sound sails made of GRP.

At the turn of the year, Hahlbrock had manufactured the new sound sails in a very short time according to the architects’ designs and the acousticians’ specifications and adhered to the client’s tight deadlines. The new mother-of-pearl ceilings ideally accommodate the hall lighting and appear to float in the orchestra room thanks to the optically delicate suspension. Thanks to the monolithic GRP shell construction, the sound sails only weigh a quarter of the old ceiling and are sufficiently rigid for three-point suspension. They meet the highest demands of today’s concert hall acoustics. High-quality surfaces and compliance with fire protection requirements were equally important criteria when selecting the GRP materials and processes.
