Acoustic calculator
Enter a room and see its estimated reverberation time against the range recommended for that kind of space, plus how much absorber it would take to get there. The absorber figures come from our own measured data sheets.
Conference and video call rooms, where clarity matters most.
Micro-perforated board fixed direct to the substrate. Absorber class B, αw 0.8.
Estimated reverberation time
0.87seconds at 500 Hz to 1 kHz
Above the recommended range for a meeting room
What it would take
Around 16 m² of proline classic, 50 mm build-up would bring this room to about 0.50 s, inside the target range.
That is roughly 22 percent of the wall area (73 m² in total) and roughly 10 percent of the total surface area of the room (153 m² in total).

This is an indicative estimate, not an acoustic report. It uses the Sabine formula with standard published coefficients for the room surfaces and our own measured data for the absorbers. Real rooms vary with shape, openings, furniture and occupancy. For a design you can build to, send us the drawings and we will model it properly or work with your acoustician.
