Auralization of Simulated Sound Fields

The audio examples on this accompany the manuscript

J. Ahrens, “Perceptually Transparent Auralization of Simulated Sound Fields” (submitted), 2024.

All audio examples are binaural, so make sure that you are listening with headphones. The examples were created with the Chalmers Auralization Toolbox. For convenience, we only provide audio examples for ambisonic auralization. It would otherwise simply be too many…

All grids have an edge length or diameter of 140 mm.

We noticed that it can depend on the headphone model that is used whether or not audible differences between auralization and ground truth occur. This is seems to be related to the fact that the most relevant differences between auralization and ground truth occur at very high frequencies beyond 10 kHz where the transfer functions of headphones can differ significantly. Please be aware of this while we are investigating it.
