Abstract [en]

Some basic parameters used in a traditional SEA calculation are coupling loss factors, modal densities, mobility and energy flow. For calculating the coupling loss factor the group velocity as well as the transmission coefficient for the energy flow from one structure to another must be known. These parameters are derived and discussed for some simple sandwich structures and are compared to the corresponding parameters for homogeneous structure.
