Abstract
In this work an energy model for the acoustic insulation of absorbing ma- terials is shown. This model is an extension of Statistical Energy Analysis (SEA) [1] in order to account for the effect of non-conservative connections [2, 3]. The energy-based approach allows to solve sound insulation problems in large domains (such as those in building acoustics) in an efficient way for the whole frequency range required by regulations (50-5000 Hz). In particular, this approach is applied here for the s...
