Obersound - Micro-perforation 1.1 mm

Obersound Micro-perforated ref 1.1W085 panels offer excellent sound absorption while preserving the aesthetics of the decor (wood, metal or solid color). This is the first Obersound micro-perforated pattern witch is available in Metal surface. The particularly discreet perforation pattern is composed of micro-holes of 1.1 mm diameter, 6 mm pitch and 3 mm spacing. The sound wave penetrates the panel through the multitude of micro-holes (+/- 55,000 holes/sq.m) and is trapped in the MDF core, thus limiting its reverberation.
