As much an institution as a restaurant, and popular with the 'stars', the problem with this establishment wasn't the knee slapping style of it's traditional Austrian entertainment, but it's location.
In a basement beneath what had in recent years become 'desirable' residential flats, the problem was that the fun could be heard throughout the building.
The sound was air and structure borne. Rossco proposed a complete solution: isolated loudspeaker mounts, insulation / absorption strategies, revised air duct work, sacrificial walls and improved glazing in the flats.
Following the calibration of a new sound system and limiter, the neighbours upstairs could finally get some sleep.
