An energy attenuation method and apparatus for a system conveying liquid under pressure. The apparatus is disposed in a liquid conveying structure of the system and includes first and second outer hose conduits, each of which respectively defines an associated first and second tuning chamber each having an inlet end and an outlet end. A tubular conduit interconnects the two hose conduits such that the chambers communicate with one another via the tubular conduit. A first tuning tube of polymeric material is disposed in the first chamber and has a first end connected to the inlet end of the first chamber for receiving liquid therein and has a second open end that is spaced from the outlet end of the first chamber for emptying liquid into the first chamber. A second tuning tube of polymeric material is mounted in the second chamber and has a first end connected to the outlet of the second chamber for conveying liquid thereto and a second open end that is spaced from the inlet end of the second chamber for receiving liquid conveyed to the second chamber via the tubing conduit. Seven additional alternative embodiments of fluid noise attenuation systems are also disclosed.
