| Abstract: | A dipole resonance scatterer of sound in the form of a short (in comparison with the quarter-wave) tube closed on one side with a stretched membrane is investigated theoretically and experimentally. The coefficient of sound transmission through the cross section of a measuring tube, into which the resonance scatterer is placed, is calculated and measured. It is shown that the waveguide is totally blocked at the resonance frequency of the resonator. |
