Perforated Timber Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
MDF or plywood panels with precision-drilled or CNC-routed perforations, backed by acoustic fleece and mineral wool. Combines natural timber aesthetics with effective broadband absorption. Available in standard patterns or custom designs.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.30 | 0.50 | 0.65 | 0.75 | 0.70 | 0.60 |
RT60 Impact
Installing 18m² of perforated timber panels in a 100m³ room reduces RT60 by approximately 0.30s at 500Hz
