Vienna Opera

For sound architect Peter Willensdorfer, each of his projects is a symphony of different acoustic solutions. In the Volksoper in Vienna, he used different compositions of sound absorbers for different areas of the building. With convincing results: the FLEXOPANEL system’s layer thickness of just 1 cm eliminated the reflection from the coving. 50% insulation effect with a fairly even absorption curve–that’s what the acoustician likes. And of course, the smooth white final surface.

For this work there is applause to this day.

The large cove in the second tier acted like a giant parabolic mirror. It reflected the sound energy and thus produced disturbing echoes. Peter Willensdorfer needed 150m² of the DEKOZELL FLEXOPANEL acoustic plaster system for this challenge. The coving was insulated with acoustic plaster to such an extent that the reflections were eliminated. Applied in a thin layer, the insulating plaster does not detract from the visual appearance and is virtually invisible during performances.

Peter Willensdorfer sums up the project best: ‘As this venue has changed from its original use as a spoken theatre to a venue for opera, the acoustic adaptation had to be geared towards the new requirements. The direct sound component was reduced, and the acoustics tuned towards music.’ In short: The solution is an acoustic quantum leap for the Vienna Opera, which today not only stages operas, but also operettas, musicals and ballets. We say thank you very much.
