Cheops® Acoustic Pyramid Panels
Cheops® Pyramids sound absorber is an attractive convoluted acoustic panel that provides a greater surface and absorptive area than flat surfaces to reduce reflected noise in a room by trapping and absorbing sound energy from all angles.
Unlike many other acoustic materials, Cheops® Acoustic Pyramid panels provide excellent acoustic control across all frequencies with Noise Reduction Coefficients ranging from 0.8 to 1.05.
Cheops® Acoustic Pyramid is available in charcoal grey colour as standard with 12 optional colours. Acoustica also offers a custom colour service to meet individual requirements.
Typical applications include broadcast and recording studios, call centres, community facilities and machinery enclosures.
Cheops® Pyramids are supplied in panels 600 mm x 600 mm and thickness of 50mm, 75 mm,100 mm or 150 mm.
For architectural applications the panels are adhered to walls and ceilings to provide a continuous and seamless pattern or can be hung as a baffle.
