Abstract: A flexible sound barrier and rigid mounting assembly, and a method of attaching to a vehicle. The sound barrier assembly includes a rigid substrate, and flexible noise barrier and decoupling layers. The decoupling and noise barrier layers are bonded, and an adhesive bonds the decoupling layer to the substrate. The decoupling and noise barrier layers are fixedly held in place by the substrate. The substrate can include slots that fit over mounting studs on the vehicle wall. The noise barrier and decoupling layers can include mounting holes that extend through both layers, where the mounting holes line up with the slots, and fit over the mounting studs. The assembly can be mounted on the mounting studs and stud fasteners can fit through a mounting hole without compressing the noise barrier and decoupling layers and sandwich the rigid substrate surrounding a slot between the stud fastener and the vehicle wall.

Abstract: A separator module for an agricultural machine. The separator module includes a feederhouse configured to receive crop from a harvesting platform, a casing enclosing a rotor positioned therein and rotatable relative to the casing for processing crop from the feederhouse, a cover extending between the feederhouse and the casing, and a noise control treatment coupled to the cover.
