When the complex connected structures with many vibration modes received stationary random vibration due to broad-band excitation, if it is assumed that the natural frequencies within the frequency bandwidth are statistically distributed, the vibrational energy of structure-borne sound are solved by Statistical Energy Analysis (SEA) method. On this method the connected structure is divided into structural elements with some similar modes, and the energy sharing of each element can be derived by dissipation and coupling loss factors. For analysis of structure-borne sound, the model of plate juction were made of concrete, and SEA was applied to between the connected plates.
