SOUND ABSORBING/INSULATING WALL
To provide a sound absorbing/insulating wall capable of effectively performing sound insulation and sound absorption in a low frequency region of 100 Hz or less without increasing the size of a resonator.SOLUTION: The sound absorbing/insulating wall includes a gypsum board 11 as an interior wall arranged so as to face a wall surface 2a or a ceiling surface 3, and a plurality of resonators 12 including a main body 12A having a hollow inside and a tubular body 12B attached to one surface of the main body 12A between the wall surface 2a or the ceiling surface 3 of a room 1 and a room 5 via a back air layer 15. The plurality of resonators 12 are attached to the gypsum board 11 so that an opening portion 12s of the tubular body 12B communicates with the back air layer 15.SELECTED DRAWING: Figure 1
【課題】共鳴器のサイズを大きくすることなく、１００Ｈｚ以下の低周波数領域における遮音と吸音とを効果的に行うことのできる吸遮音壁を提供する。【解決手段】室１の壁面２ａもしくは天井面３と室内５との間に、背後空気層１５を介して、前記壁面２ａもしくは天井面３に対向するように配置された内装壁としての石膏ボード１１と、内部が中空である本体１２Ａと前記本体１２Ａの一面に取付けられた筒体１２Ｂとから成る複数の共鳴器１２、とを備えるとともに、前記複数の共鳴器１２を、前記筒体１２Ｂの開口部１２ｓが、前記背後空気層１５と連通するように、前記石膏ボード１１に取付ける構成とした。【選択図】図１
