Virtual Acoustic Orientation Instrument

摘要

Virtual instrumentation developed to create acoustic stimuli for use asorientation signals and the rationale for selecting these target signals is described. A commercially available computer-assisted software engineered programming system, LabVIEW, was used to develop the acoustic signals and the manner of their presentation. Two different acoustic signals are presented. One sound seems to change pitch without limit, and the other is a narrow band-pass noise. The pitch, loudness, and lateral position of the signals are controlled by different functions. Listeners can control the variations in pitch and lateralization and also the rate at which these features change. Programs to generate the signals with sinusoids or with noise bands are described. LabVIEW representations of the programs are included with text descriptions.... Acoustic, Auditory, Auditory lateralization, Acoustic orientation, Flight instruments, Spatial disorientation.
