ABSTRACT:
A vibration damping laminate includes a magnetic layer and an uncoated constraining layer joined by a viscoelastic layer, wherein the modulus of elasticity of the viscoelastic layer is substantially less than that of either of the other two layers. The laminate is magnetically attached to an associated source of vibrations by the magnetic layer, and substantially all vibrational damping is effected by the viscoelastic layer.
