To reproduce a highly realistic sound field reproduction, we have developed a three dimensional sound reproduction system based on the boundary surface control principle. We set up an Internet connection among multiple systems, which enables distant speakers to carry out voice telecommunication by simultaneously hearing the same sound field and perceiving the other speakers' simulated positions as if they were in the same location. In this reproduction system, a listener can freely move his head and rotate his body because the system reproduces the sound not only at the point but at the area. In this paper, we introduce a 'Sound Cask', which is a 96-channel sound reproduction system based on the boundary surface control principle. The 'Sound Cask' is used to realize such musical telecommunication as if musical performers were all playing in the same hall. The system provides space large enough to play a small musical instrument such as violin, which allows listening and communication accompanied with natural body movements by the performer. Another specific feature of the system is that loudspeakers are installed aiming every possible direction excluding the floor. The system design is suitable for relocation as it can be assembled or disassembled when needed.
