Acoustic Stretch Wall System Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Perimeter-track fabric system with mineral wool infill behind acoustically transparent stretched fabric. Creates a seamless wall treatment from floor to ceiling. Popular in cinemas, auditoriums, and boardrooms where a clean uninterrupted fabric finish is required.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.15 | 0.45 | 0.80 | 0.95 | 0.95 | 0.90 |
RT60 Impact
Installing 20m² of stretch wall system with 50mm mineral wool in a 100m³ room reduces RT60 by approximately 0.40s at 500Hz
