Optimisation of room acoustics was a major element in the redesign of the open-plan offices and cafeteria, which featured the inclusion of communication and quiet zones. "The reason why acoustic measurements are so important is that the effect of sound in a room is not visible. Solutions are often based on "gut instinct" and have either no effect at all or, in the worst case, have a negative impact on room acoustics," explains Gerd Sinz, an architect and project controller at Rossoacoustic. The new office for Rohde & Schwarz features partitions in the form of transparent honeycomb panels from the Rossoacoustic CP 30 system. These were used to acoustically separate groups of desks, communication zones and individual working areas from one another. Acoustic pads from the Rossoacoustic PAD product family absorb sound on the ceilings and walls, as do the coarsely textured lightweight wood wool panels under the ceiling.
