A comparison of ISO 9613-2 and advanced calculation methods: Predictions versus experimental results

Panos Economou, Richard J. Peppin


Standardization provides methodologies by which independent investigations of the same situation are able to derive the same conclusions. However, standardization is sometimes also perceived as absolute and accurate, beyond which one should not investigate matters deeper. The responsibility of the accuracy of these methods does not lie with the developers but with the standards organizations. This is not the case with algorithms based on pure scientific research where the full responsibility lies with those who turn it into software applications. The Simulation and prediction of outdoor sound propagation using advanced calculation methods are based on principles of physics with an effort to try to avoid empirical or approximate methods, often found in published outdoor propagation standards.
