N2 - This paper reports an extensive near- and far-field analysis of the noise generated by an isothermal, subsonic, circular jet in the presence of a solid, flat plate shield. Far-field polar and azimuthal acoustic images are presented initially to characterize the interaction noise source. Near-field streamwise microphone phase analysis along the plate trailing edge reveals a deeper understanding of the link between the jet hydrodynamic field (both linear and non-linear regions) and the mechanisms behind interaction noise generation. Near-field point spectrum data have also been used successfully to validate Amiet's far-field trailing edge dipole prediction code for low-speed jet acoustic Mach numbers.
