Valencia, German and Agnew, Jeffrey R. (1990): Evaluation of a Directional Audio Display Synthesizer. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 6-10.

“A three-dimensional (3-D) auditory display imposes directionality to audio signals, over headphones, so that they are perceived as originating from unique spatial locations outside the listener's head. This study evaluated subjects' localization performance with a Directional Auditory Display (DIRAD) synthesizer. Subjects' ability to perceive the direction of target sounds in the azimuth plane was measured as a function of head movement with four types of audio stimuli. Results showed significant localization performance differences as a function of sound location, head movement condition and stimulus type. These results help to define the functional requirements of a 3-D auditory display prior to the integration of synthesized directional audio into flight simulators and advanced aircrew systems.”
