Abstract
Structural damping indicates the energy loss in materials and systems respectively. Hereby, different loss mechanisms must be distinguished: namely internal losses or material damping due to conversion of kinetic energy into heat and coupling losses due to transmission of energy to adjoining systems, e.g. by structural transmission at connection points or even sound radiation from a structure into a room. Having the ability to reliably measure the damping loss factor should enhance the capability of predicting the transmission loss in wall or floor assemblies.
