Abstract

In this paper, it is shown how a strategy based on algorithms for computing cuts in undirected networks, can be applied to reduce energy transmission in realistic statistical energy analysis (SEA) models, with the sole modification of a limited number of internal and coupling loss factors. The frequency dependent case of SEA systems with multiple sources and targets is considered. A mathematical justification for the strategy is also provided, which relies on an analysis of the series expansion of the energy vector, in terms of the powers of the SEA graph adjacency matrix. A numerical example of vibroacoustic transmission in a simple test building has been included to show the performance of the approach.
