Database of Acoustic Bidirectional and Random-Incidence Scattering Coefficients

Acoustic Database of Bidirectional and Random-Incidence Scattering Coefficients This dataset provides a continuously expanding collection of measured and simulated scattering coefficients. The dataset contains 3 parts as well as the workflow to generate the results: Acoustic Database of Bidirectional and Random-Incidence Scattering Coefficients contains the scatting and diffusion coefficients derived from the measured and simulated results. Simulations were performed in Aachen and Sydney. https://doi.org/10.5281/zenodo.17660108 Acoustic Database of Bidirectional and Random-Incidence Scattering Coefficients: Raw Measurements contains the measured impulse responses in free-field and diffuse field (ISO 17497-1:2004) for a broad set of rough surfaces https://doi.org/10.5281/zenodo.17660089 Acoustic Database of Bidirectional and Random-Incidence Scattering Coefficients: Simulation Results contains the simulated impulse responses in free-field for a broad set of rough surfaces mesh2scattering was used for the numerical simulations. https://doi.org/10.5281/zenodo.17660055 Workflow to generate 'Database of Acoustic Bidirectional and Random-Incidence Scattering Coefficients' contains the code to generate the database results based on the Raw Measurements and Simulation Results https://doi.org/10.5281/zenodo.17701035 This data is supplemented to: A. Heimes, D. Cabrera, J. Holmes, D. Reinhardt, I. Tokac Celikyay,S. Brell-Cokcan, M. Vorländer: Interlaboratory Comparison and Analysisof Bidirectional Scattering Coefficients for Various Surfaces (2025). under review.
