Abstract : The paper presents the results of an experimental investigation of the excitation of sound by an air stream blowing over the mouth of a resonator. It is shown that this excitation can be regarded as the result of resonance between the oscillations of a system of vortices, which are shed at the edges of the resonator, and the natural oscillations of the resonator.
