ACOUSTIC SLOT PERFORATIONS

Our various acoustic slot patterns 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.
