BRAS - Benchmark for Room Acoustical Simulation

Aspöck, Lukas; Brinkmann, Fabian; Ackermann, David; Weinzierl, Stefan; Vorländer, Michael

The Benchmark for Room Acoustical Simulation (BRAS) contains eleven acoustical scenes that are intended for the evaluation of room acoustical simulation software. This comprises simple scenes that isolate certain acoustic phenomena, as well as complex environments of different shape and size. Each scene consists of a scene description giving the room geometry, and the positions of the acoustic sources and receivers, the corresponding source and receiver characteristics, the description of the acoustic materials by means of absorption and scattering coefficients, and the measured single channel and binaural impulse responses.
  • Increased the level of detail in the 3D models and added scale pictures of scene details. Added directivity data for the dodecahedral speaker. Added fitted absorption coefficients that result in an Eyring reverberation time that matches the measured reverberation time.
