Computers' synchronization for large-scale loudspeaker array system

This paper proposes a method for synchronizing plural personal computers for developing a large-scale loudspeaker array system. Loudspeaker array system has to be controlled by a personal computer. The loudspeaker array system can generate high sound pressure areas. The loudspeaker array system is controlled with micro sec order. The loudspeaker array system is required to be enlarged for serving as a guide at a museum etc. To enlarge the system needs to increase a number of the computers. This paper proposes the method of synchronizing the plural computers by micro sec order.
