Image DescriptionMicroperforated panels are becoming a vital tool in the acoustician’s battle to reduce noise emissions. The basic concept has now been expanded to cover more applications.

The world of microperforated panels (MPP) for sound absorption has started to occupy the thoughts of acousticians over the past 10 years. Sontech started commercial production of Acustimet 15 years ago

The delicately cut holes in the 0,1-0,4mm range is creating the absorption without using any absorbant fibers or foams. There are up to 100 000 holes per sqm.
It has been used in the creation of narrowband MPP absorbers which can be tuned by hole size and the dimensions of hole distance and air gap behind the panel.
