Abstract
In the field of virtual reality, mixed reality (MR) has recently been drawing attention as a technology to experience the virtual space by superimposing the computer graphics (CG) objects in real space. The technologies to reproduce 3-Dimensional (3-D) acoustic sound fields in conjunction with MR can especially experience a higher realistic sensation than the conventional MR. A parametric loudspeaker based on an ultrasound with the higher directivity can reproduce 3-D acoustic sound fields by designing a sound image. However, it is difficult to present the realistic sensation depending on the reverberation, because an acoustic wave emitted by it shouldn't diffuse in the room. In this paper, we newly proposed to reproduce 3-D acoustic sound fields utilizing multiple parametric loudspeakers and indirect non-parametric surround loudspeakers for realizing the realistic- reverberation sensation. It could realize a higher realistic- reverberation sensation without affecting the sound image localization. The eff...
