Abstract
Sound image location associated with onset or offset disparity was quantified by a scaling procedure in each of three experiments. Steady‐state lateralization cues were minimized by using as the stimulus broadband noise which was uncorrelated at each ear. Onset and offset disparity produced lateralization toward the leading and lagging ear, respectively. For a given disparity a greater shift of the sound image in phenomenal space was obtained when the disparity was at onset rather than offset, a finding consistent with earlier work. It has been suggested [G. A. Miller, J. Acoust. Soc. Am. 20, 160–167 (1947)] that offset cues arise from the differential levels of integrated neural activity (loudness) associated with differing duration of the stimuli delivered to each ear. Two tests of this hypothesis were attempted. In one case the potency of a given disparity in producing lateralization was found to be inversely related to stimulus duration, a result in keeping with the hypothesis. However, when equal ene...
