Examines how HRTFs influence sound localization in auditory-visual settings, indicating key implications for immersive audio experiences.

The research investigates the role of HRTFs in sound source localization during auditory-visual integration in different environments.
Participants localized sound using a hemispherical loudspeaker setup.
Conditions included real loudspeakers and virtualized sounds with (non-)individual HRTFs.
Vertical spacing of loudspeakers was varied to assess discrimination.
The static and dynamic localization performance was compared.
Static experiments showed increased vertical localization confusions with non-individual BRIRs.
Dynamic localization with non-individual HRTFs exhibited similar horizontal performance to real speakers but impaired vertical mapping.
Confusion rates in the frontal area supported static findings, indicating common patterns between static and dynamic tasks.

Riedel et al. (2025) studied this question.
