In this report : part-6, Calculations and experiments on structure-borne sound propagation in multi-storied plate construction model are compared. And they are shown that calculated values are fairly coincided with measured values, by introducing some corrections for lower frequency range. This calculating method is able to predict(estimate) frequency characteristics at important frequency range. But at the higher frequency range, measured values tend to show lower values than calculated. Additionally calculation programs are applied to study of the relation between the loss factor of material and the additional structure caused mechanical damping. The relation between experimental frequency response and material loss factor are explained as structural damping by calculated values.
