Polyester (PET) Acoustic Panel Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Panels made from recycled PET plastic bottles, pressed into dense felt-like boards. Popular for sustainability credentials, pin-board functionality, and design flexibility with CNC-cut patterns and colours.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.10 | 0.30 | 0.60 | 0.80 | 0.85 | 0.80 |
RT60 Impact
Installing 18m² of 24mm PET panels in a 100m³ room reduces RT60 by approximately 0.28s at 500Hz
