Statistical Energy Analysis (SEA) method is utilized to investigate the vibration energy of structure-borne sound. This method analyses the complex connected structures with many vibration modes received stationary random vibration in broad-band excitation, if the natural frequencies within the frequency bandwidth are statistically distributed. The present paper describes equations of power balances and coupling loss factors between coupled systems from theoretical perspective. The paper also discusses the diffuse vibration field of plates and the transmission efficiency of junctions in detail. Moreover, the author calculated the "average" transmission efficiency using reciprocity relations by three incident bending, longitudinal, transverse waves. A series of experimental investigation was conducted by using the "average" transmission efficiency.
