The contribution deals with measurement of acoustic absorption coefficient for different single or double-layer materials: cork, two layers of polyethylene, polyethylene and felt. The measurement was performed on an impedance tube of our own construction, using the two-microphone method transfer function (ISO 10534-2: 1998) and the PULSE measuring system. Values of the acoustic absorption coefficient for the frequencies from 100 Hz to 1600 Hz were determined experimentally. Subsequently, those values were processed graphically.
