SOUND ABSORPTION AND SOUND INSULATION MATERIAL AND ENCLOSURE
To provide a sound absorption and sound insulation material which not only exerts sound absorption performance but also can improve sound insulation performance for insulting passage of sound to an opposite side of a sound source on a side where the sound source exists.SOLUTION: A sound absorption and sound insulation material 1 comprises a hollow boad B having one or more core layers C which are three-dimensionally formed, and two facing skin layers S1 and S2 for sandwiching the core layers C. The hollow board B comprises a plurality of small chambers X and communication spaces Y isolated from the small chambers X in an inner space region R formed between the skin layers S1 and S2. At least a part of partition walls Z partitioning the respective small chambers X from the communication spaces Y and outside the hollow board B is constituted of the skin layer S1, the communication space Y is sealed at an end 21 of the hollow board B, an inside of the communication space Y is filled with liquid L, and small holes H for communicating outside the hollow board B and the small chambers X are opened in the skin layer S1 constituting a part of the partition walls Z of the small chambers X.SELECTED DRAWING: Figure 5
【課題】音源が存在する側において吸音性能を発揮するだけでなく、音源と反対側への音の通過を遮断する遮音性能をも高めることができる吸音遮音材を提供する。【解決手段】立体的に成形された１層以上のコア層Ｃと、当該コア層Ｃを挟持して対向する２層のスキン層Ｓ１、Ｓ２とを有する中空ボードＢを備え、前記中空ボードＢは、前記スキン層Ｓ１、Ｓ２間に形成される内部空間領域Ｒに、複数の小室Ｘと、これら小室Ｘから隔離された連通空間Ｙとを有し、前記各小室Ｘを前記連通空間Ｙ及び中空ボードＢ外部から区画する隔壁Ｚの少なくとも一部が前記スキン層Ｓ１により構成され、前記連通空間Ｙが前記中空ボードＢの端部２１において封止され、当該連通空間Ｙの内部に液体Ｌが充填され、前記小室Ｘの隔壁Ｚの一部を構成する前記スキン層Ｓ１に前記中空ボードＢ外部と前記小室Ｘを連通させる小孔Ｈが開通する吸音遮音材１を採用する。【選択図】図５
