This data set contains stimuli and results from two experiments for human localisation of virtual sound source simulated via binaural synthesis using head related impulse responses (HRIRs). The corresponding binaural room scanning (BRS) files for the binaural simulation can be found in the directory `brs`. The employed noise stimulus is contained in `stimuli`. The localisation results are stored in `results` together with a text file to describe the content in more detail. The `analysis` directory includes scripts for the statistical evaluation and reproduction of the figures in the paper.
Abstract of the Publication:
Sound Field Synthesis reproduces a desired sound field within an extended listening area using up to hundreds of loudspeakers. The perceptual evaluation of such methods is challenging, as many degrees of freedom have to be considered. Binaural Synthesis simulating the loudspeakers over headphones is an effective tool for the evaluation. A prior study has investigated, whether non-individual anechoic binaural synthesis is perceptually transparent enough to evaluate human localisation in sound field synthesis. With the used apparatus, an undershoot for lateral sound sources was observed for real loudspeakers and their binaural simulation. This paper reassesses human localisation for the mentioned technique using a slightly modified setup. The results show that the localisation error decreased and no undershoot was observed.
