Abstract: Method and apparatus for suppressing noise in machinery a having movable element and fixed element in close proximity to the movable element is disclosed. The movable element and fixed element may coact to disturb the atmosphere and produce noise. A fluid system is provided for inducing a pressure variation proximate to the movable element and fixed element to thereby reduce the level of noise.
