Differences between considered studies with respect to methodological details and data availability. Visible refers to the visibility of a loudspeaker at the intended source location. Model simulations were either compared with the reported average results retrieved from the original publications (Avg.) or on the basis of individual results from N listeners. Modeled parameters are formatted in upright font, ignored parameters in italic font. For instance, the duration of stimuli was not considered in the model. In fact, non-spatial properties of the source signal besides its frequency bandwidth were only considered for Exps. I & II. In all other cases, the model was applied directly on the HRTFs or BRIRs.

Exp. Study Signal Bandwidth Duration Azimuth Reverb Visible Data
I and II [33] Tone complex 0.1–5 kHz 1 s 37° none yes Avg.
III [17] White noise 0.05–6 kHz 4 s 0°, 50° 200 ms yes Avg.
IV [34] White noise 1–16 kHz 0.5 s 0°, ±90° none no N = 10
V [35] Speech varied 3 s 30° 350 ms yes N = 3
