This paper deals with the problem of sound propagation in urban areas, a real tool leading to smart cities design. It begins by studying the propagation of sound in order to determine and extract the physical parameters that direct this propagation. Then it deals with the formalism of cellular automata and their relation to the specification of physical phenomena with discrete events, such as s...
The propagation of sound in a density-stratified fluid is examined in an experiment with a tank of salty water whose density increases continuously from the fluid surface to the tank bottom. Measurements of the height dependence of the fluid density are used to calculate the height dependence of the fluid salinity and sound speed. The height-dependent sound speed is then used to calculate the r...
Predictive skill for outdoor sound propagation is assessed using high-resolution atmospheric fields from large-eddy simulations (LES). Propagation calculations through the full LES fields are compared to calculations through subsets of the LES fields that have been processed in typical ways, such as mean vertical profiles and instantaneous vertical profiles synchronized to the sound propagation...
