Monitoring the Simultaneous Presentation of Multiple Spatialized Speech Signals in the Free Field
Abstract
The effect of spatial auditory information on listeners ability to detect, identify, and monitor multiple simultaneous speech signals was evaluated in the free field. Factorial combinations of three variables, including the number of localized speech signals, the location of the speech signals along the horizontal plane, and the sex of the talker were employed using a within-subjects design. Participants were required to detect the presentation of a critical speech signal among a background of non-signal speech events. Results indicated that the spatialization of simultaneous speech signals (1) increased the percentage of correctly identified critical signals and (2) lowered ratings of perceived mental workload as compared to a non-spatialized control condition.
