Abstract

This paper examines the acoustic characteristics of a Helmholtz resonator experimentally using a two-microphone transfer function method and numerical modeling. The experiment was conducted in the Perm State University in Aerodynamics Laboratory using a set-up whose central element is an impedance tube. The impedance and sound absorption coefficient were determined during the experiment and then compared with the results of mathematical modeling performed numerically using the finite element method in the LOGOS Aero-Hydro package. Satisfactory agreement between the calculations and experimental data was achieved in the frequency range most commonly used in practice.
