The meeting rooms of the Leuthard Bau AG company in Merenschwand (AG) were very echoing, and a meeting in the respective rooms was very uncomfortable to hold. For the individual meeting rooms, the volume was used to calculate which size (m2) of suitable absorbers had to be installed in order to bring the reverberation time down to a recommended level. At the same time, the management wanted to be able to use the area as an image and advertising medium. With the chosen acoustic images, all wishes were met and the rooms are now acoustically renovated and ready for use.
