Absorption values

The measurements of the absorption coefficient were performed on PUR-ES acoustic foams from RWTH Aachen. All values refer to absorbers with a size of 100 cm x 50 cm and were calculated according to DIN 52212.

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.

Profit from sound insulation directly from the manufacturer!

At aixFOAM we make sound insulation for applications in room acoustics and technical acoustics. And because we do this particularly well, we have been doing it for 60 years. Over this time we have been constantly working on the further development of our products and therefore are able to offer you highly effective sound absorbers in a modern design.

Our aixFOAM philosophy: We combine customer-oriented advice with the individual, needs-based production of sound insulation solutions.
