PROBLEM TO BE SOLVED: To provide sound absorbing structure that has the great effect of reducing a floor impact sound and a wall radiation sound.SOLUTION: There is provided sound absorbing structure 1 which is placed on a ceiling 1 and absorb a floor impact sound of an upper floor. The sound absorbing structure 1 comprises a first sound absorbing body 11 that has a granular material 13 and a first container 14 for accommodating the granular material 13 and that is placed on a top surface of a ceiling board 31 of the ceiling 3, and a second sound absorbing body 12 that has the granular material 13 and a second container 15 for accommodating the granular material 13 and that is placed on a top surface of a substrate material 32 of the ceiling 3. The first sound absorbing body 11 is fixed to ceiling board 31, and the second sound absorbing body 12 is fixed to the substrate material 32.
【課題】床衝撃音や壁放射音の低減効果が高い吸音構造を提案する。【解決手段】天井３に上載されて上階の床衝撃音を吸収する吸音構造１であって、粒状体１３と当該粒状体１３を収容する第一容器１４とを有し、天井３の天井板３１の上面に上載された第一吸音体１１と、粒状体１３と当該粒状体１３を収容する第二容器１５とを有し、天井３の下地材３２の上面に上載された第二吸音体１２とを備えていて、第一吸音体１１は、天井板３１に固定されており、第二吸音体１２は下地材３２に固定されている。【選択図】図１
