    Abstract: Systems and devices are disclosed herein for absorbing unwanted target sounds. In one example, an acoustic scatterer for absorbing a target sound includes a housing defining a plurality of channels having an open end and a terminal end. The terminal ends of the plurality of channels are separate from each other and extend along a length of the housing. The acoustic scatterer also includes one or more spacers subdividing the plurality of channels along the length of the housing. In another example, a system for absorbing a target sound includes a plurality of acoustic scatterers, each having a housing that defines a plurality of channels having an open end and a terminal end. The terminal ends of the plurality of channels are separate from each other and extend along a length of the housing. The plurality of acoustic scatterers are stacked on top of each other in a lengthwise direction.

    Abstract: The present teachings generally relate to an acoustic panel including a backing layer, honeycomb core attached to the backing layer, a mesh layer attached to the honeycomb core, and a face sheet including a flexible acoustic fabric face sheet attached to the mesh layer. The acoustic fabric face sheet can provide improved sound dampening characteristics over, for example, a perforated face sheet, and at a lower manufacturing cost, weight, and a simplified manufacturing process. The acoustic fabric face sheet can be or include a flexible woven and/or knitted fabric including a polymer such as an aromatic polyamide that includes a meta-aramid fiber, or a fiberglass fabric.

    Abstract: Apparatuses, systems, and methods for vehicle floor silencers include a silencer wall extending from a floor of the vehicle floor silencer and creating a barrier between an unsecured portion of a wire harness and a shift lever boot. The floor can be configured to be mounted to a vehicle support liner. The silencer wall can protrude from the floor. The silencer wall can be located immediately adjacent the shift lever boot (e.g., the silencer wall can at least partially define an opening through the floor so as to accommodate the shift lever boot). The vehicle floor silencer (i.e., the floor and the silencer wall in combination) can be fabricated as a single, monolithic piece.

    Abstract: An all-terrain vehicle includes a frame, a vehicle cover, a plurality of wheels, a suspension, a prime mover assembly with an engine and a transmission, and an intake system. The intake system includes an air inlet on an instrument shield providing cooling air to the transmission. The instrument shield windward surface extends transversely, upwardly and rearwardly at an angle to horizontal in the range of 45 to 90 degrees. The vehicle cover includes left and right side cover assemblies each with insulation covers. The prime mover assembly is in an accommodation space extending inside of the left and right insulation covers, substantially isolated from contact with the left and right insulation covers by airflow within the accommodation space. Flow-guiding cavities are defined adjacent wind-in surfaces on the underside(s) of left and/or right front fenders, and the flow-guiding cavities introduce airflow into the accommodation space.

    Abstract: [Problem] To realize, by means of a simple structure, a soundproofing material having a soundproofing property equal or superior to that of a conventional one against sound including noise arising from vibration generated by a panel (dash panel) that separates the inside and outside of a vehicle cabin or an automotive component and penetrating into the vehicle cabin, and further to realize an excellent soundproofing property in a method for attaching an automotive component using the soundproofing material.
    [Solution] An automotive soundproofing material made of a urethane foam material, characterized in that the urethane foam material has a single-layer structure, the urethane foam material is configured to have either a uniform thickness or an increased thickness only in a region where it is needed, and an automotive component can be installed while compressing the urethane foam material.

    Abstract: A transfer cooling structure of a vehicle is provided, the vehicle including a power source, a transmission, and a transfer device provided with a torque-distribution-control friction clutch, disposed in the order from forward of the vehicle. The structure includes a floor provided to the vehicle and having a tunnel part configured to cover a transmission case of the transmission and a transfer case of the transfer device from above, an insulator attached below the tunnel part to cover the transmission case and the transfer case while having a gap with respect to the transmission case and the transfer case, and a cooling acceleration part provided to the insulator protruding toward the transfer case from the floor side.
