Comparing Room Acoustics Simulation Tools: Dataset for Reproducing and Expanding the Results

This is the database connected to the paper Dijkman, L., Hoekstra, N. and Hornikx, M. Comparing Open-Source Room Acoustics Simulation Tools: Performance and Usabillity Insights (2025). This database contains the following information: Simplified room geometries for Complex Room 2 (CR2) and Complex Room 4 (CR4) from the Benchmark for Room Acoustical Simulation (BRAS). Material data (absorption, scattering and approximated reflection coefficients) for all materials in both rooms. Source and receiver positions (x, y, z) according to the simplified room models. All simulation results for the simulation tools used in the research. Scripts for post processing of the results. For an overview of all research on open-source simulation tools for room acoustics conducted by the TU/e Building Acoustics group, see: https://github.com/Building-acoustics-TU-Eindhoven/OSS_RoomAcoustics References @inproceedings{Dijk2025c, author = {Luc Dijkman and Niels Hoekstra and Maarten Hornikx}, title = {{C}omparing {O}pen-{S}ource {R}oom {A}coustics {S}imulation {T}ools: {P}erformance and {U}sability {I}nsights}, booktitle = {{P}roceedings of the 11th {C}onvention of the {E}uropean {A}coustics {A}ssociation {F}orum {A}custicum / {E}uro{N}oise 2025}, year = {2025}} @techReport{Aspo2020, author = {Lukas Aspöck and Michael Vorländer and Fabian Brinkmann and David Ackermann and Stefan Weinzierl}, doi = {10.14279/depositonce-6726.2}, institution = {RWTH Aachen}, keywords = {Room acoustic simulation,acoustic modeling,virtual acoustic}, title = {\{B\}enchmark for \{R\}oom \{A\}coustical \{S\}imulation (\{BRAS\}) - \{D\}ocumentation of the database}, year = {2020}} @article{Mond2020, author = {Boris Mondet and Jonas Brunskog and Cheol Ho Jeong and Jens Holger Rindel}, doi = {10.1016/j.apacoust.2019.04.034}, issn = {1872910X}, journal = {Applied Acoustics}, keywords = {Absorption coefficient,Inverse problem,Room acoustics,Surface impedance}, publisher = {Elsevier Ltd}, title = {\{F\}rom absorption to impedance: \{E\}nhancing boundary conditions in room acoustic simulations}, volume = {157}, year = {2020}} @inproceedings{Berz2017, author = {Marco Berzborn and Ramona Bomhardt and Johannes Klein and Jan-Gerrit Richter and Michael Vorländer}, booktitle = {DAGA}, title = {\{T\}he \{ITA\}-\{T\}oolbox: \{A\}n \{O\}pen \{S\}ource \{MATLAB\} \{T\}oolbox for \{A\}coustic \{M\}easurements and \{S\}ignal \{P\}rocessing}, year = {2017}} Revision history Version Date (yyyy-mm-dd) Changes 0.2.0 2025-11-01 Added *.3ds file for room CR4.
