Abstract
A split cylinder compliant tube baffle for absorbing and/or canceling noise signals generated within a submarine or surface ship is described. The split cylinder tube baffle includes an air-filled tube having a longitudinal gap extending the length of the tube. The baffle further comprises a rubber jacket for enclosing the gap and end covers for sealing end portions of the tube. A split tube baffle assembly is generally constructed of tube baffles adjacently aligned to form a panel. The panels can then be stacked for increased attenuation of acoustic signals. The split cylinder baffle offers significant size reduction and improved performance over conventional compliant tube baffle designs.
