Abstract
In the framework of ISO/TC 43/SC 1/WG 56 Working Group, the ISO 17534 series of standards and technical reports is being developed to deal with the quality assured implementation of calcula- tion methods for the outdoor noise propagation. The ISO 17534 series is currently composed of two general documents (ISO 17534-1 and -2) as well as a technical report (TR) dedicated to ISO 9613-2 propagation method (ISO 17534-3). A new TR dealing with CNOSSOS-EU is currently focusing the attention of the WG. In connection with this WG, and in the wake of the publication of NMPB 2008 method (standardized in AFNOR NFS 31-133:2011 French standard), similar works have been carried out in France. On the one hand, a number of additional recommendations were prepared to correct mistakes or clarify ambiguities present in NFS 31-133:2011 document, in order to reduce the risk of mistakes in the implementation of this standard. On the other hand, a set of test-cases has been defined and documented in order to help software developers check the good implementation of this method, taking as a basis ISO 17534-3 format and content. In these test-cases, specificities of NFS 31-133 are checked such as long distance propagation, industrial source description, embankments, retrodiffraction, vehicle body-barrier interaction. The paper proposed to this session aims at presenting this work in close articulation with CNOSSOS-EU implementation.
