The aim of the work presented in this article was to estimate sound energy transmission at asymmetrical junctions in buildings. Several kinds of tee-shape and cross-shape joints have been investigated. Theoretic calculation model to obtain transmission loss has been concluded and equation system was fixed. After the equation system is solved, we receive expressions to predict transmission coefficient (transmission loss). Using this procedure for different structural connections, the simplified calculation formulas for different cases of asymmetrical joint were received. With the help of the received equations the basic parameters are determined and those parameters influence the sound energy damping in the connections of the building. The received results may be applied for evaluation of influence of indirect noise transmission via different asymmetric connections of the building.
