The wiki for Micro perforated plate

I do not have access to Potential of microperforated panel absorber by Dah-You Maa

I have a small sample of SoundPly Acoustic Panels | Acoustically, Structurally & Visually Superior. but there should be more sources in Europe. There was even a translucent plastic foil acting as a micro perforated absorber available.
