Annotation
The work is devoted to the study of absorption characteristics of the Helmholtz resonator in the channel. Discusses models of the Helmholtz resonator with and without taking into account the presence in the cavity resonator the wall boundary layer. The results of the calculations are compared with experimental data obtained when measuring the acoustic properties of the resonator in the impedance tube.
