Sensorimotor Coupling in Virtual Audio: Psychoacoustic Studies on the Minimum Audible Angle with 6 DoF Movement
* Präsentierender Autor
Zusammenfassung:Virtual reality systems with 6-degrees-of-freedom tracking enable sensory information to be rendered in real time in response to the listener's motor actions. The minimum audible angle (MAA) has been studied with a stationary listener and a stationary or a moving sound source. The studies at hand focus on a scenario where the angle is induced by listener self-translation in relation to a stationary sound source. First, the classic stationary listener minimum audible angle experiment is replicated using a headphone-based reproduction system. This experiment confirms that the reproduction system is able to produce a localization cue resolution comparable to loudspeaker reproduction. Next, the self-translation minimum audible angle (ST-MAA) is shown to be 3.3° in the horizontal plane in front of the listener. Furthermore, in contrast to stationary listener MAA, the ST-MAA is shown to be unaffected by an additional visual cue.
