Abstract
Movement detection for a virtual sound source was measured during the listener’s horizontal head rotation. Listeners were instructed to do head rotation at a given speed. A trial consisted of two intervals. During an interval, a virtual sound source was presented 60° to the right or left of the listener, who was instructed to rotate the head to face the sound image position. Then in one of a pair of intervals, the sound position was moved slightly in the middle of the rotation. Listeners were asked to judge the interval in a trial during which the sound stimuli moved. Results suggest that detection thresholds are higher when listeners do head rotation. Moreover, this effect was found to be independent of the rotation velocity.
Highlights
For azimuthal sound localization, we use the interaural time difference and the interaural level difference (Blauert, 1997)
Previous reports have described that if a sound is presented during head movement, the sound localization accuracy is reduced (Brimijoin and Akeroyd, 2014; Cooper et al, 2008; Masumi, Honda, et al, 2014; Masumi, Suzuki, et al, 2014)
This experiment involves the following issues: First, the angular amount of virtual sound source movement differed between two conditions
Summary
We use the interaural time difference and the interaural level difference (Blauert, 1997). They reported the result that presentation of sound stimulation during head rotation movement caused reduction in the sound image localization accuracy compared with a case in which the head is not moved. This study examined sound image movement detection during horizontal head rotation using the VAD.
