A gas compression apparatus and method are disclosed, according to which an impeller (12) rotates to flow fluid through a casing (10), and a plurality of vanes are mounted on a plate (20) in the casing. A series of cells (34a-c/36a-c) are formed in the plate (20) to form an array of acoustic resonators to attenuate acoustic energy generated by the impeller. <IMAGE> |
