Description
The simulation of urban sound propagation is challenged by the strong impact of diffraction around building edges.Although several geometric propagation models can account for diffraction, their validation is hindered, because real-world measurements are inherently noisy or do not exist.For this reason, this work presents a database of scale-model measurements specifically designed for urban environments with an emphasis on diffraction.The database includes measurements of different urban scenarios, ranging from simple terraced houses to more complex configurations with multiple buildings, varying source-receiver placements and different scale factors.Due to the reduced scale, the measurements could be performed in an anechoic chamber, reducing the influence of noise and other environmental factors.The database is made publicly available to facilitate the validation of sound propagation models in urban environments and to encourage further research in this area.
