It is the aim of this paper to develop a strategical method for the determination of SEA total loss factors (TLFs) and some of the coupling loss factors (CLFs) for built-up structures based on the recent development of in situ measurement techniques and the Statistical Energy Analysis theory. An obvious advantage of the method is that the determined TLFs would include the dissipation of coupling, and 'automatically' share the dissipation loss of the coupling to each coupled subsystem. The present strategy provides an applicable means for determination of total loss and some coupling loss factors of built-up structures for high frequency structure borne vibration and sound prediction. Satisfactory results of numerical experiments of the present strategy have been achieved
