Conformity to ISO 17534-1:2015 ============================== .. This document has been generated with noisemodelling-tutorial-01/src/main/java/org/noise_planet/nmtutorial01/GenerateReferenceDeviation.java Clarifications on the ISO Standard and Identified Issues ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ It is important to note that the ISO standard provides recommendations rather than regulatory obligations. While it serves as a reference framework, its application is not mandatory from a legal standpoint. During our analysis, we identified several issues within the standard that hinder a complete and reliable comparison. Notably, we observed inconsistencies between 2D and 3D visualizations, preventing us from achieving a coherent assessment. Additionally, discrepancies exist between the geometric description of the scene and the corresponding acoustic response, raising concerns about the accuracy and reliability of the standard’s methodology. Furthermore, with respect to favorable rays, our findings indicate a different implementation of CNOSSOS compared to the approach suggested by the standard. This divergence may have implications for the interpretation and reproducibility of results, necessitating further clarification and alignment.
