In this study, subjects had to localize sound sources in free‐field listening conditions and in virtual environments. Under virtual listening conditions, three auditory displays with distinct degrees of individualization were used. In contrast to previous studies using verbal reports or pointing techniques, the participants indicated the perceived location of a sound source by turning their eyes toward it. Localization performance under virtual conditions was comparable to free‐field conditions for all subjects, at least if individual HRTFs were used. In general, judgments turned out to be more accurate than in previous studies, especially with regard to dispersion of single judgments. This may be due to a close link between the auditory and the oculomotor system, leading to a quasiautomatic saccade toward an auditory stimulus, even without a corresponding visual target. |
