Promotion Effect of Sound Image Location by Unity Audio-Visual Interaction

Based on audio-visual interaction of Unity, we built a sound image localization subjective evaluation platform in the form of a game and compare it with a conventional platform. The experiment shows that 3D scenes and animation effects of Unity can effectively relieve fatigue, the way using head rotation to find the direction of sound source can make the result get closer to the certain sound azimuth. The direction wheel can prompt the azimuth value, which makes the measurement more accurate. The loudspeakers can achieve higher resolution by this platform.
