Abstract
Yost and Zhong (2015, JASA, 137, 2200) recently showed that sound source localization when listeners rotate depends on both spatial cues and information about the world-centric location of the listener. In these experiments, the sound was a broad-band (0.125—15 kHz), 200-ms noise burst. This stimulus does not allow for an estimation of the role of interaural time (ITD) and/or level (ILD) differences in sound source localization when listeners rotate. The present experiment used the following stimuli: low-pass noise (0.125–0.5 kHz) implicating ITD cues, high-pass noise (2–8 kHz) implicating ILD cues, broad-band noise (0.125–8 kHz) implicating both ITD and ILD cues, and mid-frequency noise (1–4 kHz) for which neither an ITD nor an ILD cue provides good information about sound source location. Listeners rotated at constant velocity (45o/sec) in the azimuth plane, while sounds changed position around a 24-loudspeaker array in the same azimuth plane. Listeners responded in an eyes-open condition in which they ...
