Perforated Metal

The perforated metal acoustic panel helps absorb sound, prevent unwanted acoustic reflections and limit reverberations, with the ability to be installed as both wall and ceiling panelling, or as individual sheets or planks to be installed on a variety of surfaces including doors. Acting as a Helmholtz Absorber, an air filled cavity behind the perforated surface acts as a resonator, while a layer of dense fabric or other such porous absorbent behind this absorbs; ‘trapping’ and dampening sound waves to reduce acoustic transmission. Mid density perforations such as this are typically suited to medium volume and capacity spaces, due to a medium size and density of perforation opening size and location.
