A numerical and experimental study of micrometeorological effects on urban sound propagation

Résumé

Within the framework of the EM2PAU project, this study aims to quantify the influence of micrometeorological effects on sound propagation in a street canyon, both numerically and experimentally. The numerical approach leads to specific developments of the Parabolic Equation (PE) method in order to take into account such physical phenomena. Qualitative and quantitative results are presented and discussed. In addition, an experimental approach is carried out through monitoring measurements of both acoustical and meteorological data in a ½ scale street canyon. Experimental results are presented and discussed, regarding numerical model validation and statistical exploration. This statistical analysis of experimental data shows the real stakes for considering such micrometeorological phenomena in urban sound propagation.
