Acoustic Cloud Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Horizontal panels suspended below the structural soffit with air gaps above and below. Absorb sound on both faces and edges. Available in rectangular, circular, and custom shapes from mineral wool, metal, or fabric-wrapped cores.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.25 | 0.60 | 0.85 | 0.95 | 0.95 | 0.90 |
RT60 Impact
Installing 12m² of cloud panels (both faces exposed) in a 100m³ room reduces RT60 by approximately 0.40s at 500Hz
