At some operating conditions shrouded jets are observed to undergo an intense howling resonance. The coupling of vortical modes in the jet with acoustic modes at the shroud exit, which potentially close the resonance loop, are investigated with a vortex sheet model, which is solved using scalar Wiener-Hopf techniques. Peculiar sensitivities to flow parameters are observed that might explain the sporadic character of the observed howling resonance.
