Do individual HRTFs matter for localization, front-back confusion and externalization in head-tracked headphone playback, and how do room reverberation and training modify the answer?

In one open-access head-tracked VR experiment (Jenny & Reuter 2020; 39 listeners, headphones, free field, noise from a visible moving drone), listeners rated their own measured HRTF as easier to localize, easier to externalize and more natural than the KEMAR or two other nonindividualized HRTFs, and reported front-back confusions in 27% of KEMAR responses versus 0% with their own. A 2020 review reports mixed results for externalization in reverberant conditions (no individualization effect in Begault 2001 and Leclere 2019; a gain in Werner 2016), and a 2021 Acta Acustica abstract reports that adding a dry room response accelerated learning of non-individual HRTFs. Which factor dominates in reverberant, head-tracked content is not settled by the sources read.

Curator qualifications: Jenny & Reuter 2020 (39 listeners, head-tracked VR): own measured HRTF rated easier to localize/externalize and more natural than KEMAR/generic. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
