A QRD diffuser is an acoustically hard surface which, because of its calculated 3D-design, scatters sound waves that strike it both spatially and spectrally. The diffuser can do this within a targeted working range, usually the range in which fundamental musical tones are found (c4 octave).
Our Quadratic residue diffusers (QRD) can be an essential and powerful tool in the acoustic optimization of any room in which high-end sound (=read Natural sound) reproduction is a goal. Opera’s – studio’s etc… all use diffusers for correct & natural sound (also the human voice is very clear & very good audible without false “ringing” in the room)
