ABSTRACT:
A sound reduction system (40) reduces noise generated by a fluid cutting jet (10). The fluid cutting jet moves along a predetermined path of travel to pass the stream across another object (14) for cutting the object. The system includes a tank (42) for collecting the liquid stream from the fluid cutting jet. A plurality of tubes (46) are supported in the tank for directing the liquid stream into the tank. The tubes are arranged side-by-side in the tank along the path of travel of the stream. The tubes are positioned in the tank with their upper collection ends (54) extending above the tank and their lower drainage ends (52), directed towards the bottom of the tank. A cover (64) caps the collection ends of the tubes. A thin aperture (63) is formed in the cover to allow entry of the liquid stream into the tubes.
