The purpose of this study was to isolate and investigate specialized auditory stimuli with respect to spatial orientation. An evaluation of subjects' ability to use frequency specific binaural clues and vision, separately and in combination, in setting the horizontal position of a rod-and-frame device was performed. The data demonstrated that the auditory clues improved performance regardless of the presence of visual stimuli. The combination of auditory and visual clues provided the optimal arrangement. The implications for human factors design in aircraft systems are discussed. (Author).
