Title
(EN) SOUND ABSORBING BODY AND SOUND ABSORBING STRUCTURE
(FR) CORPS D'ABSORPTION SONORE ET STRUCTURE D'ABSORPTION SONORE
(JA) 吸音体、および、吸音構造
Abstract
(EN) This sound absorbing body is provided with a main body having a bottomed cylindrical shape with an opening portion and a bottom portion, and a porous sheet covering the opening portion. The main body is provided between the opening portion and the bottom portion with at least one hole which is larger than holes with which the porous sheet is provided, and which penetrates through the main body.
(FR) L'invention concerne un corps d'absorption sonore, qui comprend un corps principal ayant une forme cylindrique à fond avec une partie formant ouverture et une partie formant fond, et une feuille poreuse recouvrant la partie formant ouverture. Le corps principal est disposé entre la partie formant ouverture et la partie formant fond avec au moins un trou qui est plus grand que des trous que comporte la feuille poreuse, et qui pénètre à travers le corps principal.
(JA) 吸音体は、開口部と底部とを有した有底筒状を有する本体と、前記開口部を覆う多孔質シートと、を備える。前記本体は、前記開口部と前記底部との間に、前記多孔質シートが備える孔よりも大きく、かつ、前記本体を貫通する少なくとも1つの孔を備える。
