This AlphaPerf® Metal Acoustic Panel is a modular wall unit consisting of a metal or aluminum frame surrounding a perforated metal skin, with encapsulated acoustical sound absorber. The perforated metal allows sound waves to enter the absorbing material where a portion is transformed from sound energy to heat. AlphaPerf® Metal Wall Panels are used primarily as a sound absorber in potentially noisy environments such as gymnasiums, swimming pools, pump rooms, and industrial fabrication work areas.
