Sound Transmission Coefficient (STC) rating for acrylic
A barrier’s sound reduction depends on its weight per square foot, rigidity and air tightness. In airtight surroundings, sound reduction increases with increased sheet thickness.
| SHEET THICKNESS | AVERAGE SOUND TRANSMISSION(DB) LOSS 100-3200 HZ | STC RATING FOR ACRYLIC | STC RATING FOR POLYCARBONATE |
| 3.0 mm (1/8”) | 22 | 23 | 25 |
| 4.5 mm (3/16”) | 25 | 26 | 29 |
| 6.0 mm (1/4”) | 28 | 28 | 31 |
| 9.5 mm (3/8”) | 30 | 30 | 34 |
