ABSTRACT OF THE DISCLOSURE An arrangement for damping and absorption of sound in rooms, and in particular to provide a sound damping even at very low frequencies e.g., 50 Hz and simultaneously improve speech comprehension in the entire room by reduction of the resonance time as well as to be able to vary the acoustic absorption and in that way even vary the resonance time over the entire part of the frequency area. The sound absorbents in the form of plates mats or the like are arranged at an angle with at least one corner area formed by the walls and ceiling of the room. In the corner area behind the absorbent an air volume is trapped so that the absorbent due to the sound influence has a membrane effect. The in- clination and for position of each absorbent can be varied individually or in group.
