Abstract
There is a need for in situ experimental estimation of loss factors and proper subsystem division when analysing assembled systems using statistical energy analysis (SEA). On the basis of a physical measure, the modulation transfer function computed from the squared impulse-response, a method has been developed for this purpose, see Fahy and Ruivo (1997), Lundberg (1997).
