Outline of Final Research Achievements

We developed acoustic space separation system based on individual phase control of carrier and sideband waves. As a result, the development of the proposed system was completed and its performance was evaluated. The research result was published as a journal paper. Furthermore, as a research that applied this technology, we developed the technology of acoustic hologram which creates virtual sound source in three dimensional space and evaluated its performance. The research result was also published as a journal paper. In addition, we also promoted various researches applying the research results. As a result, the research results include one patent, seven journal papers and 21 international conferences.
