Description
はじめに、本実施の形態に係る防音室の概要について説明する。なお、本実施の形態において、音の発生源に近い側(部屋の中心側)を「前方」、遠い側を「後方」という。
次に、本発明の実施の形態2に係る防音室の吸音構造について説明する。本実施の形態では、吸音構造が、低音域の音響を可変とする機能を有している。
図17は、実施の形態2の変形例に係る吸音構造1Bを模式的に示す断面図である。吸音構造1Bは、低音音響可変機構5Aを備えている。低音音響可変機構5Aは、上記低音音響可変機構5と同様に仕切り部材51を含んでいるが、その配置位置、および、通路面積の調整の仕方が、低音音響可変機構5とは異なる。
次に、本発明の実施の形態3に係る防音室の吸音構造について説明する。本実施の形態では、吸音構造が、全音域の音響を可変とする機能を有している。
上記実施の形態1〜3では、横幅2Pの側壁を有する防音室を例に説明したが、それ以外の横幅の側壁に囲まれた防音室にも、上記したような吸音構造を適用可能である。この場合の防音室の構成例について説明する。
上記各実施の形態の吸音構造では、前方面部材22と開口部23とが横幅方向に隣接するように配置されることとしたが、これらは上下方向に隣接して配置されてもよい。この場合、図21に示される側壁92のように、上下方向中央部に開口部23が設けられてもよい。
