Sonic System acoustic modular panel-V50

The Sonic System acoustic modular panel V50 is engineered to control airborne noise through a combination of sound absorption and sound attenuation, making it suitable for industrial environments where reverberation control and moderate noise reduction are required.

Featuring a 50mm Rockwool core with a perforated internal steel face (38% open area) and solid external skin, the V50 delivers strong mid- to high-frequency absorption while maintaining effective barrier performance. Sound absorption is measured to AS ISO 354 and airborne sound transmission loss to AS 1191-2002, with Rw determined to AS/NZS ISO 717.1. The panel achieves NRC 1.00 and Rw (C;Ctr) 31 (−1;−5), with transmission loss reaching 52.1 dB at 5000 Hz.
