Sound absorber/ sound insulation in the reverberation chamber when determining the absorption values
Our aixFOAM sound absorbers have been tested for Hertz and pores in the reverberation chamber of renowned institutions such as RWTH University or the Technical University in Aachen. The sound absorption coefficients according to DIN 52212 stated above were calculated in extensive measurements.

‘The heavy acoustic foam HEAVY Duty is the perfect product for any sound insulation area. With its high mass, it absorbs noise effectively and stops the transmission of structure-borne sound. It is suitable both as footstep dampening under the pressure distribution layer in floorings, and as sound insulation in sound studios and for decoupling drums or singing booths.’
