The purpose of this paper is to reduce edge tone generated by flow of a jet-wedge system. An attempt to reduce the edge tone has been carried out by attaching projecting objects to the nozzle exit. It is found that the edge tone is reduced even though a pair of projecting objects is attached to the nozzle exit. In addition, the flow patterns of the jet oscillation are visualized by the color tracer injection method.
