Summary:PURPOSE:To realize a Hass effect localizing sound image corresponding to the position of a player in a theater or a sound hall. CONSTITUTION:Plural antenna systems 211, 222,... are arranged in an area for position discrimination and a communication available range of the antenna systems are partly overlapped. Moving tags 251, 252 send a signal having a specific identification number by access from the antenna system and a signal from a tag in the communication available range is received by a predetermined antenna system. Then the position of the tag is discriminated based on location data of the antenna system receiving the signal from the tag 251. When the plural antenna system receive the signal from the tag, the antenna system receiving signal is established based on reception signal intensity and the position of the tag is recognized by location data.
