Abstract :
The paper describes the results of complex wall impedance measurements and the influence to the eigenfrequencies and Q-factors of cavity resonators. The prediction of the eigenfrequency of cavity resonators under non-ideal reflection conditions is technical relevant to develop acoustic gas sensors for industrial use.
