Category Discription In this category you find ready made panel - and perforated absorbers. On this page we want to present you a short description on how these absorbers work: Panel Absorbers Panel absorbers are made out of thin panels that are mounted in a certain projection from a wall or ceiling. The „space“ between Panel and wall is filled with materials like mineral wool – The panel is the mass and the filling is the spring. Both together build a mass-spring system. The resonance frequency of this system determines in which frequency range this absorber is most effective. The sound energy is converted into kinetic energy. This type of absorber is mainly used for average and lower frequencies. There is a wide range of panel absorbers that are designed and produced individually but many manufacturers deliver ready made panel absorbers that have been optimized for certain frequency ranges. Perforated Panel Absorbers The surface of perforated panel absorbers is - in comparison to „normal panel absorbers“ - perforated. These panels have equally spaces holes in the shapes of circles, quadrats or trenches. These absorbers are often used in ceiling structuring and wall covering.
