Abstract
Abstract A composition for vibration damping of a structure releasing vibrational energy through its surface is disclosed. The composition includes either a substantially non-homogeneous visco elastic damping layer on the surface of the structure, or a visco elastic damping layer that is either homogeneous or non-homogeneous discontinuously attached to the surface of the structure. The non-homogeneity of the damping layer is caused by substantially planar voids, substantially spherical voids, or particles. The discontinuous attachment of the damping layer and the surface of the structure is caused by a plurality of grooves, indentations, or by the presence of a non-adhesive material where the damping layer and the surface structure are not secured.
