Localization of Virtual Auditory Cues in a High +Gz Environment

Abstract

The ability to localize a virtual auditory source was evaluated under varying levels of sustained (+Gz) acceleration. Participants were required to judge the locations of virtual auditory cues located along the horizontal plane (elevation 0 ) during exposure to 1.0, 1.6, 2.5, 4.0, 5.6, and 7.0 +Gz. The experiment was conducted at the Air Force Research Laboratory's Dynamic Environment Simulator - a man-rated, three-axis centrifuge. No significant increases in localization error were found between 1.0 and 5.6 +Gz; however, a significant increase did occur at the 7.0 +Gz level. In addition, the percentage of reversals did not vary as a function of +Gz level. Collectively, these results indicate that one's ability to localize virtual auditory cues is well maintained at various levels of sustained acceleration.
