Add to ORKGUsing a parallel flow approximation, a simple model of hydrodynamic instability is proposed for describing the behavior of an orifice as an acoustic amplifier. It is shown that the growing of perturbations in the vena contracta can generate negative damping for Strouhal numbers of the order of 0.2-0.5. Experimental data are provided to support the modelization: a qualitative agreement is obtained
