Theory of Three-Dimensional Sound Field Reproduction

Abstract

臨場感の高い音響を実現するため，様々な音場再生技術が研究開発されている．これらは，心理音響モデルに基づく方式と，物理音響モデルに基づく方式に大別できる．前者としては，5.1サラウンドから22.2マルチチャネル音響に至る様々な方式が提案されている．いずれも，2チャネルステレオの音像制御方式を基本としており，チャネル数を増やすことで，音場再生能力を向上させている．一方，後者は，音の物理量再現を目的とした方式であり，Wave Field Synthesisや境界音場制御法など，音の場の再現を目指す方式と，アンビソニックスに代表される，受音点での音の物理量を再現する方式に分けることができる．本稿では，これらの方式の基本技術を概観するとともに，その背景となる理論を紹介する．
