An experimental study of acoustic resonance generated by a submerged water jet has been carried out using various size of the nozzle and various jet velocities. Sound pressure level is measured by a hydrophone in a small water tank. It is found that the jet with water mixed and the jet without air mixed show higher SPL level than the conventional jet with air mixed. Furthermore, SPL level for the jet without air mixed persists in the downstream section. In addition, the optimum nozzle size and the optimum jet velocity are investigated.
