  • Multi-chambered sound attenuation with resonant frequency targeting
    Patent number: 11236653
    Abstract: An apparatus for engine exhaust sound attenuation includes a housing, a plurality of baffle plates arranged within the housing. The baffle plates are disposed apart from each other to define a plurality of intermediate chambers. The plurality of intermediate chambers includes a first resonant chamber proximate to the outlet chamber, a second resonant chamber proximate to the inlet chamber, a first intermediate chamber proximate to the second resonant chamber, and a second intermediate chamber proximate to the first intermediate chamber and the first resonant chamber. An inlet tube and an outlet tube are included. A first tube directs a flow of exhaust from the inlet chamber to one of the plurality of intermediate chambers via an interior of the first tube. Additionally, a second tube directs the flow of exhaust from a second one of the plurality of intermediate chambers to the outlet chamber via an interior of the second tube.
