Understanding the Performance and Design of Micro Perforated Acoustic Panels
Micro perforated acoustic panels are a relatively new architectural sound absorption technology and they are applied in all kinds of buildings and structures. These panels are designed with very small perforations, usually less than a millimeter in diameter, which effectively control the reflection of the sound and suppress noise. Contrary to conventional acoustical materials, which utilize foam or fiber, the micro perforated panels are made of solid surfaces that are breathable because of the holes that are drilled to high precision. This will enable them to capture the combination of functionality as well as beautification, thus apt in contemporary design settings. How Micro Perforation Works for Sound Absorption The physics of Micro Perforated Acoustic Panels is that sound waves react with the holes that are built at a microscopic level. When the sound waves reach the panel surface, they penetrate these micro holes and produce friction as they pass through air in these holes, and s...
