| Outline of Final Research Achievements |
In order to improve the overall performance of a sound field reproduction system, a system consisting of 24 narrow directional microphone arrays and the same number of loudspeakers was investigated. The performance of the system was evaluated using both physical measurements and human subjective evaluations, based on the assumption that the performance depends on the following four conditions: A) physical basis for the reproduction, B) robustness against inevitable disturbances such as the presence of listeners, C) room for additional effects, and D) high compatibility with video information.
The results show that beamforming, which limits the nature of the signal during recording, is very effective. In addition, it was found that video information significantly improved the sense of immersion. However, there was some compatibility with the content.
