The sound absorption material property knowledge, opens new application possibilities of material.
Absorptive materials can be used for sound pressure level attenuation in interior spaces (usually
acoustic diffuse field), as well as exterior spaces (free acoustic field). The presented work is focused
on sound absorption coefficient measurement techniques. In respect to this purpose, the standing
wave impedance tube measurement device was assembled. Reference samples from composite based
EVA (ethylene vinyl acetate) material were created. Samples were used for interlaboratory
comparative sound absorption measurement test. Measurement results comparison is presented here.
