Sound Insulation and Sound Absorption - Oskar Pahlke GmbH

Sound insulation hinders the propagation of sound by reflecting sound waves at a separating surface. Sound insulation serves to acoustically isolate rooms from unwanted noise from neighboring rooms or the outside. In contrast, sound damping or sound absorption reduces sound energy by partially converting or absorbing it. This results in less reverberation and better room acoustics. For sound insulation, materials with a high density are particularly used, such as environmentally friendly recycled composite foams with a density of at least 120 kg/m³. On the other hand, for sound damping, PUR soft foams are particularly suitable due to their open-cell structure and the associated increased surface area.
