Research Projects

  • 多次元時空間スペクトルにおける特異点に着眼した音オブジェクト抽出・再生手法の確立

    次世代の聴覚メディアにおいては,音オブジェクトの抽出が肝となる。本研究では,小規模マイクロホンアレイによる高精度な音オブジェクト抽出の実現を目指す。その原理として,アレイ出力の音響信号を画像と見なした場合に,目的音の到来方向が,その時空間スペクトルにおいて特異点となることを利用する。すなわち,時空間スペクトルを画像と見なした場合に,目的音抽出が空間直流成分の画像修復と同様に扱えることを利用する。

  • 音楽信号を用いた電子打診による体調管理の支援可能性の探求

    物理的打撃によるインパルス応答の測定である「打診」は,古くから体内の状態を知る有効手段であった。本研究では,「音楽(メロディ)が聞こえる試験信号(5秒程度)」を体表面から振動子により与え,インパルス応答を算出することを電子打診と称する。
    まず,健常者を対象とした臓器位置の推定という課題を通じて,電子打診システムを構築する。続いて,妊婦を対象にして,電子打診による胎位の推定を行う。また,SN比の高い体表位置を特定し,胎児心拍数を計測する。さらに,肺炎治療中患者を対象として電子打診を行い,胸水の溜まり具合の推定に挑む。これらを通じて,電子打診による体調管理支援の可能性を探究する。

    音声インタフェースが身近な存在となり,また米国・韓国ではテレビのオブジェクトベースオーディオ放送が開始されるなど,所望の音のみを抽出することが有益な場面が増えている。本研究では,眼鏡フレームに搭載可能な程度の小規模マイクロホンアレイにより,高精度な目的音抽出の実現を目指す。その基本戦略として,アレイ出力を画像と見なした場合に,その時空間スペクトルにおいては音源位置が特異点となることを利用する。特に,方向が同一で距離のみが異なる複数音源からの抽出を可能とすることに意義があり,これにより空間全体を音オブジェクトの集合として分解できることを示す。
