Timber Slat Acoustic Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Parallel timber slats (solid or MDF) with gaps, backed by acoustic felt or mineral wool. The slats resonate at specific frequencies and sound passes through gaps to the absorber. Combines design aesthetics with mid-range absorption.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.25 | 0.40 | 0.55 | 0.65 | 0.60 | 0.55 |
RT60 Impact
Installing 18m² of timber slat panels in a 100m³ room reduces RT60 by approximately 0.25s at 500Hz
