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.

3 cm
5 cm
8 cm
125 Hz 0,10 0,17 0,23
250 Hz 0,50 0,73 0,75
500 Hz 0,78 0,71 0,73
1000 Hz 0,63 0,59 0,64
2000 Hz 0,49 0,57 0,59
4000 Hz 0,53 0,45 0,70
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.
