The quantity of modules is determined by the room’s size and shape, the materials of walls, ceiling and floor, the furniture and the usage of the room and also your individual preferences. For instance, a room with 5 m x 4 m x 2,5 m, concrete walls and ceiling and a laminate floor can be fitted with the following modules:
- Control room with a reverberation time of 0.3 sec: 12 basstraps + 22 absorbers + 22 diffusors
- HiFi room / home cinema with a reverberation time of 0.5 sec: 6 basstraps + 10 absorbers + 16 diffusors
- Rehearsal room / recording room with a reverberation time of 0.7 sec: 4 basstraps + 8 absorbers + 12 diffusors
As a guideline you can assume 1 module per m³ for control rooms and 0.5 modules per m³ for rehearsal rooms.
