The rapid development of 3D video stimulates demand for 3D audio and promotes the research on perceptual characteristics in 3D sound field. The traditional researches of 3D orientation characteristics were measured sensitivity for some specific locations on site. The test efficiency and results are not good to practical application. This paper first designed a new device to collect optional position in order to establish a 3D sound database and proposed a test method which can be large-scale test. It can ensure the consistency of the experimental data and can't interfere by the experiment pers...
