Abstract	The subject of this paper is the redesign a flat panel to couple less effectively to acoustic enclosures, and improve transmission loss between the enclosures. First presented is a brief background of the theory of acoustic noise in reverberant enclosures. Finite dimensional acoustic and structural models are linked producing a fully coupled linear control design model. These developments are then specifically applied to a 3D acoustic chamber consisting of two separated 4ft times 4ft times 8ft enclosures. Passive redesign of the structure for minimal coupling and several mass mimicking active noise controllers were investigated. A decentralized MIMO controller was designed and simulated to mimic the effect of additional mass. These models and designs are currently being validated on an experimental test bed. Future efforts will examine additional control design strategies including modal clustering, passification by optimal blending of sensors and actuators, and the use of locally reacting sources on the plate surface to target acoustic structure coupling directly
