Claim:
A jet nozzle apparatus comprising: a nozzle housing; and a shield generally in a shape of a visor spaced from a trailing edge of the nozzle housing and extending over an arc of less than about 180 degrees, that interacts with an output flow from the nozzle to affect noise generated by an output flow exiting the nozzle housing; said shield having a central portion and a pair of arm portions extending from the central portion that taper to distal ends, the shield, when in an operative position, positioned such that the central portion covers at least a trailing edge of said nozzle housing and also extends downstream beyond the trailing edge of the nozzle housing; and the shield, when in the operative position, having an interior surface of the central portion spaced a distance corresponding to approximately 1/12 a diameter of the nozzle housing, from an exterior surface of the nozzle housing.
