Acoustic - Acoustic patterns - Perforation
Pattern: Perforation
Application: Tile with perforation pattern is suitable for wall cladding, ceiling, furniture, and other applications where sound insulation characteristics are preferred
Standard pattern:
Micro-perforation T-8, regular pattern, front ∅ 0.05" and rear ∅ 0.19", c-t-c 0.31", αw (Alpha value) is 0.50, NRC is 0.65
Optional patterns:
Medium-perforation T-16, regular pattern, front ∅ 0.11" and rear ∅ 0.19", c-t-c 0.63", αw is 0.65, NRC is 0.65
Macro-perforation D-16, regular pattern, front ∅ 0.19" and rear ∅ 0.19", c-t-c 0.63", αw is 0.40, NRC is 0.45
Special patterns: Upon request
Acoustic testing: Test results and data shown are based on ISO 354:1985, according to EN 20354, 1993 acoustic measurement of sound absorption in a reverberation room, ISO 11654:1997 acoustic sound absorbing for use in buildings and ASTM-C-423-90a acoustic standard test method for sound absorption coefficients by the reverberation room method. All these tests were carried out on veneered and varnished panels, complete with perforation patterns, with an acoustic fleece on the reverse of each panel and a 2 inch stone wool layer with a density of 2.89 lb/ft³. Measurements and calculations were carried out on a 1/3 octave band with a bandwidth of 125 - 4000 Hz
Reference for sound absorption measured: The actual degree of sound absorption (αw) and Noise Reduction Coefficient (NRC) is influenced by the distance between the panel and the building wall or ceiling as shown in the diagrams
