The ability to localize a virtual auditory source was evaluated under varying levels of sustained (+G z ) 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 +G z . The experiment was conducted at the Air Force Research Laboratory's Dynamic Environment Simulator -a man-rated, threeaxis centrifuge. No significant increases in localization error were found

Collectively, these results indicate that one's ability to localize virtual auditory cues is well maintained at various levels of sustained acceleration.
