  • Method and apparatus for reducing structural vibration and noise
    Patent number: 9725154
    Abstract: A conjugate damper for a structural panel includes a constraining sheet extending between a first edge and a second edge. Each of the first edge and the second edge is at least partially coupled to a first surface of the structural panel. The conjugate damper also includes a damping layer coupled between the constraining sheet and the first surface such that, when the structural panel is in a compressively deformed state, a thickness of the damping layer in a direction generally normal to the first surface is decreased relative to a baseline state. The damping layer includes a viscoelastic material.
    Type: Grant
    Filed: May 13, 2014
    Date of Patent: August 8, 2017

  • Noise reduction system for composite structures
    Patent number: 9353518
    Abstract: A method and apparatus comprising a composite panel and a number of structures to reduce noise radiation from the composite panel. The composite panel has a first face sheet, a second face sheet, and a core located between the first face sheet and the second face sheet. The number of structures is associated with the first face sheet. The number of structures has a mass with a configuration to reduce a speed of waves propagating in the composite panel such that noise radiating from the composite panel is reduced.
