Cork Wall Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Natural or agglomerated cork panels, typically 3-12mm thick. Low-to-moderate absorption performance. Valued for sustainability credentials, warmth, and bulletin-board functionality. Better as part of a combined treatment strategy.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.05 | 0.10 | 0.15 | 0.25 | 0.30 | 0.35 |
RT60 Impact
Cork panels alone provide limited absorption. Installing 15m² in a 100m³ room reduces RT60 by approximately 0.06s at 500Hz
