1. A conjugate damper for a structural panel, said conjugate damper comprising:

  • a constraining sheet extending between a first edge and a second edge, wherein each of said first edge and said second edge is at least partially coupled to a first surface of the structural panel; and

    a damping layer coupled between said constraining sheet and the first surface such that when the structural panel is in a compressively deformed state, a thickness of said damping layer in a direction generally normal to the first surface is decreased relative to a baseline state, said damping layer comprises a viscoelastic material.
