Patent ID: 8128076

Claim:
A noise attenuator for attaching a load bearing wall panel to a frame that is subjected to vibratory loads, wherein said attenuator includes: a rigid core comprising an elongated tubular sleeve having a front plate located at one end of said sleeve and a rear plate located at the other end of said sleeve, said plates each having an end face that is normal to the longitudinal axis of said sleeve; a bracket having an opening that encircles a portion of said sleeve between said front and rear plates; a single elastomeric bushing that is bonded to said core and to said bracket so that the single bushing fills the space between said front and rear plates; a plurality of voids that pass longitudinally through said at least one of said front and rear plates and which extends axially substantially through said single bushing between said bracket and said sleeve; fastening means for securing one of the rear and front plates of said core tightly against said one of said frames and said load bearing wall panel; and mounting means for attaching said bracket to the other of said load bearing wall panel and said frame such that said bracket is radially loaded from the weight of the load bearing wall panel, said voids being oriented such that the non-voided regions of said bushing are placed under a combined tension and shear or a combined compression and shear in order to provide attenuation.
