Development of Real System in Near 3D Sound Field Reproduction System Using Directional Loudspeakers and Wave Field Synthesis

摘要

It is very important to develop near 3D sound field reproduction techniques in order to realize the ultra-realistic communications such as 3D television and 3D tele-conference. In this paper, the near 3D sound field reproduction system using directional loudspeakers and wave field synthesis is developed by constructing the surrounding microphone array, where 157 microphones are attached on the 5 planes of the rectangular room, and the radiated loudspeaker array, where 157 loudspeakers are directly attached to the 5 planes of the rectangular enclosure. The performance of the developed system is evaluated by displaying the developed system to general public at the exhibition.
