- Abstract
- For the reproduction of 3-D acoustic images, the horizontal plane of loudspeakers should be extended to vertical directions using additional loudspeakers. In this paper, 32 channel double layered loudspeaker arrays were proposed for the reproduction of sound images in front of a listener. For the localization of virtual sources in both azimuth and elevation, WFS based rendering method is used. First of all, 2-D wave field is synthesized by virtual loudspeaker array, and then each column of upper and lower loudspeaker pair generates virtual loudspeakers by vertical amplitude panning using calculated elevation vectors. Subjective listening test comparing proposed method to 3-D VBAP were conducted for the evaluation of frontal localization quality in this system.
