The space was 170 m² with a 3.2 m ceiling: 544 m³ of air, a hard floor and bare walls. Reverberation time reached 2.04 s in the low bands. In a room like that, a voice from one desk arrives at the next still sounding, and a full day in it is tiring without anyone knowing why.
We installed 32 panels in five sizes and four fabrics, spread across the reflective surfaces rather than concentrated on one wall. Sixteen of them are reference 81, which on its own contributes 10.24 m². In total 17.96 m² of absorbent surface: 10.6% of the floor area.
Reverberation fell to 1.2 s in the low bands and to 0.96 s in the 500 Hz band, where the voice lives. Between 630 Hz and 3.15 kHz the drop exceeds six tenths; in the two highest bands it settles at around half a second. These are measurements taken before and after in the same space, not a catalogue estimate.
