Commercial Loop Pile Carpet Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Heavy-duty loop pile carpet on underlay, standard in commercial offices and hotels. Provides moderate high-frequency absorption but minimal low-frequency performance. Contributes more to impact noise control than airborne absorption.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.05 | 0.10 | 0.20 | 0.35 | 0.50 | 0.55 |
RT60 Impact
Installing 30m² of loop pile carpet in a 100m³ room reduces RT60 by approximately 0.15s at 500Hz
