●SoundTex sound-absorbing nonwovens is a sound dissipation and can beachieved by means of very thin absorbers presenting an appropriate soundimpedance. A porous sound-absorbing material is our acoustic nonwovenSoundTex. On porous sound-absorbing materials.sound energy is mainlyconverted into thermal energy by viscous friction between the oscillatingparticles of the sound-propagating medium (air) and the structure of theporous material.
