Wool Felt Acoustic Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Pressed wool felt panels (typically 9-12mm thick) used as wall tiles or ceiling features. Natural material with moderate mid-high frequency absorption. Pin-board functionality. Often combined with thicker absorbers for broadband performance.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.08 | 0.20 | 0.45 | 0.70 | 0.80 | 0.75 |
RT60 Impact
Installing 15m² of 12mm wool felt panels in a 100m³ room reduces RT60 by approximately 0.18s at 500Hz
