A former bathhouse from 1900 was converted to a conference location. In the centre is a round central hall connecting all the additional spaces. This large hall with a high ceiling takes up a great volume. Because of hardly any sound absorption in this hall, the echo time was long and created noise pollution in the other spaces. Atis International substantially reduced the echo time with SonoSober sound-absorbing ceiling and wall elements. By carefully determining the height-width relationship and hanging photos opposite each other, we achieved the desired result… An area partially surrounded by acoustic paintings that together form two large panorama photos of natural landscapes!
