STANDARD ACOUSTIC PERFORATION

Our various standard acoustic perforation are tested and documented to achieve known sound absorption coefficients for both walls and ceilings. Certain sounds need to be directionally steered and others reduced or eliminated. We therefore recommend designers to consult with a professional acoustican in order to achieve the required results.

General Bezel conditions for wall panels

B and C = 30 mm.
When group perforation, B and C can vary between 30-95 mm

General Bezel conditions for Ceiling panels

B and C = 40 mm.
When group perforation, B and C can vary between 40-95 mm
