Title
Auditory Localization under Sustained +Gz Acceleration
Abstract
The ability to localize a virtual sound source in the horizontal plane was evaluated under varying levels of sustained (+G(z)) acceleration. Participants were required to judge the locations of spatialized noise bursts in the horizontal plane (elevation 0 degrees) during exposure to 1.0, 1.5, 2.5. 4.0, 5.5, and 7.0 +G(z). The experiment was conducted at the U.S. Air Force Research Laboratory's Dynamic Environment Simulator, a three-axis centrifuge. No significant increases in localization error were found between 1.0 and 5.5 +G(z); however, a significant increase did occur at the 7.0 +G(z) level. In addition, the percentage of front/back confusions did not vary as a function of +G(z) level, Collectively, these results indicate that the ability to localize virtual sound sources is well maintained at various levels of sustained acceleration. Actual or potential applications include the incorporation of spatial audio displays into the human-computer interface for vehicles that are operated in acceleration environments.
