Abstract
A method and system for a tone generator assembly are provided. The tone generator assembly includes a resonance chamber that includes a first end and a second end and a body extending therebetween. The body surrounds a cavity therein, wherein the first end includes a resonance chamber opening in flow communication with the cavity. The tone generator assembly also includes a nozzle having a bore therethrough. The bore includes an inlet opening configured to receive a flow of relatively high pressure fluid and an outlet opening coupled in flow communication with the inlet opening and configured to discharge an underexpanded jet of fluid when the flow of relatively high pressure fluid is received at the inlet opening. The resonance chamber and the nozzle are positioned relatively and sized to facilitate emitting a tone from the tone generator assembly having a frequency less than two kilohertz.
