In virtual auditory display, sound source motion is typically cued through dynamic variations in two types of localization cues: the inter-aural time delay (ITD) and binaural spectral cues. Generally, both types of cues contribute to the perception of sound source motion. For certain spatial tra jectories, however, namely those lying on the surfaces of cones of confusion, ITD cues are absent, and motion must be inferred solely on the basis of spectral variation. This paper tests the effectiveness of these spectral variation cues in eliciting motion percepts. A virtual sound source was synthesized that traversed sections of a cone of confusion on a particular sagittal plane. The spatial extent of the source’s trajectory was systematically varied to probe directional discrimination thresholds.
