Patent number: 11446980Abstract: A sound damper and associated system are disclosed for damping sound. In embodiments, the sound damper is utilized within an automotive HVAC system. A passage wall defines an air passageway that transmits air. The sound damper includes a micro perforated panel (MPP) located within an opening formed into a passage wall. A back wall is spaced from the MPP, and a cavity is provided between the back wall and the MPP that is outside the air passageway. In embodiments, the MPP can be covered by a non-perforated film that is acoustically transparent and air impermeable.Type: GrantFiled: March 5, 2021Date of Patent: September 20, 2022Assignee: DENSO INTERNATIONAL AMERICA, INC.Inventors: Prakash Thawani, Stephen Sinadinos, Joseph Burtch
