Original Abstract

This work deals with realisation of laboratory instrument focused on measurement of sound absorption coefficient of low frequency acoustic resonating systems. Construction based on the mechanism of impedance tube using transfer-function method is chosen with operating frequency chosen between 30 Hz - 200 Hz. Proposed impedance tube was constructed, and its functionality was verified using a set of Helmholtz resonators. Vibration properties of the tube were tested by the means of additional measurement using accelerometers.
