Micro-perforated panels work through a different mechanism than standard perforated products. Conventional perforations are large enough to see, typically 3mm to 10mm, and rely on the open area behind the hole for absorption. Micro-perforations are a fraction of that size. At this scale, sound energy is converted to heat through viscous friction as air molecules interact with the hole boundary.

The result is a panel that absorbs sound without any visible evidence of the perforations. From across the room, a Stealth panel is indistinguishable from solid wood paneling. Move closer and the perforations become barely detectable on close inspection, but they’re small enough that the wood grain reads as fully continuous and uninterrupted. Nothing about the surface says “acoustic treatment.” It reads as premium architectural millwork.

The surface absorbs light softly rather than reflecting it, giving the wood a warm, velvety visual quality. Acoustic performance is measurable and testable to ASTM C423.
