Lecture
This lecture introduces SonROAD18, a new road noise emission model developed to address the limitations of the outdated StL86+. The presentation covers the requirements, modular structure, emission calculations, vehicle categories, and surface corrections of SonROAD18. It also discusses the comparison with existing models, software implementations, and the validation process. The lecture emphasizes the model's state-of-the-art approach, predictability of source impact, detailed vehicle categorization, and compatibility with the CNOSSOS model.
