Abstract in different language: This paper deals with possibilities of measuring resonance frequency of absorbing elements using the loudspeaker. Commonly used methods for determine absorbtion coefficient α are not suitable for prototypes design. For verification in the reverberation chamber a large sample area is required. In impedance tube can be measured only small circular samples. The method, which is described in the paper, is based on change of the loudspeaker impedance characteristics due to placing prototype of the absorbing element into a common baffle.
