An evaluation of three-dimensional audio displays for use in military environments

G.R. Arrabito


A relatively new technology, the three-dimensional (3-D) audio display, has been proposed for improving operator performance. However, many of the studies supporting 3-D audio displays have been conducted in controlled laboratory settings and it is not clear if all gains in performance will transfer into corresponding real-world applications. The Canadian Department of National Defence (DND) and the defence forces in allied nations are presently investigating 3-D technology for use in operational environments. The implications of the use of 3-D audio technology in real-world applications and recommendations for further research are discussed in this paper.
