Corner Bass Trap Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Triangular or cylindrical absorbers designed for room corners where low-frequency standing waves accumulate. Typically dense mineral wool (48-96 kg/m³) or membrane absorber construction. Essential for recording studios and critical listening rooms.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.50 | 0.70 | 0.75 | 0.80 | 0.75 | 0.65 |
RT60 Impact
Installing 4 corner bass traps in a 100m³ room reduces RT60 at 125Hz by approximately 0.25-0.40s
