The aluminum micro-perforated acoustic panel features a 1.0mm thick face panel with perforations smaller than 0.1mm. It effectively prevents water penetration and has excellent anti-permeability properties. With a punching rate of less than 1%, it is a resonance sound-absorbing structure composed of thin plates and rear cavities. The micro-wave structure on the surface of the micro-perforations changes the transmission path with the clever design of ribs, absorbing a large amount of particle impact energy. The micro-perforations within the trough create a friction effect on the air particles passing through oblique micro-perforations, causing velocity differences and resulting in particle compression and energy loss, achieving sound energy attenuation through resonance in the cavity to obtain excellent sound absorption performance.

The aluminum micro-perforated acoustic panel possesses sound absorption characteristics. The composite material used on the back has a compensatory effect, providing a wide sound absorption frequency range and exhibiting full-frequency absorption properties. It is lightweight, non-toxic, fire-resistant, waterproof, salt-resistant, dust-resistant, and has high stain resistance and a long service life. It is widely used in commercial spaces such as airport waiting areas, subway public spaces, high-speed rail waiting rooms, power plants, sports arenas, hospitals, and more.
