It was used to limit acoustic reflection and noise in large vaulted ceilings.〔William J. Cavanaugh, Gregory C. Tocci, Joseph A. Wilkes, ''Architectural Acoustics: Principles and Practice,'' Hoboken: John Wiley and Sons, Inc., 2010. 71.〕 The most prevalent use was to aid speech intelligibility in cathedrals and churches prior to the widespread use of public address systems. Akoustolith was bonded as an additional layer to the structural tile of the Tile Arch System ceilings built by the Raphael Guastavino Company of New Jersey. Akoustolith was a patented product of a collaboration between Rafael Guastavino Jr. and Harvard professor Wallace Sabine over a period of years starting in 1911. ==References== John Ochsendorf, Guastavino Vaulting: The Art of Structural Tile, New York: Princeton Architectural Press, 2010. 133. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Akoustolith」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
