Abstract
The invention discloses a parametric system for testing a capability of auditory spatial positioning and a method of providing a parametric minimum audible angle. The system includes: an host computer system calculating spatial movement data and communicating with a slave computer; a spatial movement system realizing control of any spatial position through circumferential movement, radial movement and vertical movement; a real-time three-dimensional display system built into the host computer system; an audio system randomly generates a type of audio data of a sound source and a sound source with equal-difference decibels; and a test system for matching human spatial positioning results to sound source spatial data and providing an objective evaluation. The invention further provides a method of providing a parametric minimum audible angle for a capability of auditory spatial positioning, the invention improves the control accuracy.
