Metodik för att förfina prediktering av stomljud

Research Project, 2023 – 2025

Within the project "Development of methodology for ground-borne noise in road andrailway projects" funded by the Swedish Transport Administration, a designmethodology for ground-borne noise has been developed. The project has been runwithin the framework of a doctoral position and has been end reported in June 2023. Alicentiate presentation is planned for September 2023. In the project, the need forfurther development for more relevant cases and increased precision has been identified.The project in the current application aims to continue within the framework of thedoctoral position to further develop the methodology and the model, for instance makingadjustments based on feedback, include ballast-free tracks and structural sounddampening measures, manage the variations in the connection between rocks andbuildings and develop a recommended methodology for measurements under theconstruction stage to achieve increased precision in the prediction. The project has beendeveloped in dialogue with representatives of the Swedish Transport Administration's IV,PL and NS: Alf Ekblad PLkvh, Magnus Källman IVmv2, Maria Luisa Botella IVmv2 (NStechnical design).
