Mateo, Julio C., Simpson, Brian D., Gilkey, Robert H., Iyer, Nandini and Brungart, Douglas S. (2012): Spatial Multisensory Cueing to Support Visual Target-Acquisition Performance. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 1312-1316.

“The impact of spatial multisensory cues on target-acquisition performance was examined. Response times (RTs) obtained in the absence of spatial cues were compared to those obtained when tactile, auditory, or audiotactile cues indicated the target location. Visual scene complexity was manipulated by varying the number of visual distractors present. The results indicated that all these spatial cues effectively reduced RTs. The benefit of cueing was greater when more distractors were present and when targets were presented from more eccentric locations. Although the benefit was greatest for conditions containing auditory cues, tactile cues alone had a large benefit. No apparent advantage of audiotactile cues over auditory cues was observed, suggesting that the auditory cues provided sufficient information to support performance. Future research will explore whether audiotactile cues are more helpful when the auditory cues are degraded (e.g., when presented in noisy environments or in generic virtual auditory displays).”

Good, Michael D. and Gilkey, Robert H. (1992): Masking between Spatially Separated Sounds. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 253-257.

“The development of optimal three-dimensional auditory displays requires a more complete understanding of the interactions among spatially separated sounds. Free-field masking was investigated as a function of the spatial separation between signal and masker sounds within the horizontal, frontal, and median planes. The detectability of filtered pulse trains in the presence of noise maskers was measured using a cued, two-alternative, forced-choice, adaptive staircase procedure. Signal and masker combinations in low (below 2.3 kHz), middle (1.0-8.5 kHz), and high (above 3.5 kHz) frequency regions were examined. As the sound sources were separated within the horizontal plane, signal detectability increased dramatically. Similar improvement in detectability was observed within the frontal plane. As suggested by traditional binaural models, interaural time cues and interaural intensity cues are likely to play a major role in mediating masking release in both the horizontal and frontal planes. Because no interaural cues exist for stimuli presented within the median plane, traditional models would not predict a release from masking when the stimuli are separated within this plane. However, with high frequency signals, masking release similar to that observed in the horizontal and frontal planes could be observed in the median plane. The current literature suggests that sound localization in the median plane may depend on direction-specific spectral cues that are introduced by the pinna at high frequencies. The masking release observed here may also depend on these "pinna cues."”
