CTMedia at ICA 2010

The CTMedia La Salle was at ICA 2010, the 20th International Congress on Acoustics, held in Sidney, Australia, 23-27 August 2010. The ICA is an international recognized congress that takes place every three years since 1953. Dr. Oriol Guasch presented the paper “Ranking energy paths in a SEA model” authored by Oriol Guasch and Àngels Aragonès. Abstract A link between graph theory and statistical energy analysis (SEA) has been recently established. This allows resorting to the former to solve many issues related to energy transmission paths in SEA models. In this work, we benefit from this connection to implement an algorithm for ranking the set of K maximum energy transmission paths from a source subsystem to a target subsystem, in a SEA model. Problems arising if the stochastic nature of loss factors was to be incorporated in the computation of paths are also outlined. The algorithm can prove very useful for the noise control engineer. For instance, knowing whether energy transmission between sources and targets in a SEA system is drawn by a limited set of paths or not, can be helpful to determine noise control treatments. Moreover, is it at the core of the existence of transmission loss regulations between dwellings.
