抄録

To a achieve highly immersive auditory experience, physically accurate sound field reproduction is required. Many local sound field synthesis (SFS) methods have been proposed to accurately reproduce the sound field around a listener. However, the narrow listening area in local SFS prevents the listener from moving freely. In this study, we developed a dynamic 2.5-dimensional local SFS system, which moves the listening area to follow the movements of the listener using a body-tracking camera. For the evaluation the proposed system, the azimuth localization accuracy was investigated by measuring interaural level differences in an anechoic chamber. The results show that when the distance between the listener and the virtual point source is 1.0 m, the proposed system has a small azimuthal localization error compared with conventional SFS.
