AB  - In order to design efficient 3D audio coding and rendering systems, it’s important to understand how spatial resolutions of human hearing are affected by sound source directions and its bandwidths. However, sufficient study has not yet been done with this problem. We therefore investigated the spatial resolution of human hearing with different azimuths, elevations, and bandwidths of the source signal. We also provide measured results, which will be useful to design 3D immersive audio systems. When the azimuth angles of the sound source signals come to the lateral side of a listener, or when the bandwidth of the source signals become narrower, the resolution decreases. Additionally, when the elevation angles of the source signals become larger, the resolution decreases.
