SOUND ABSORBER, ADJUSTMENT METHOD OF SOUND ABSORBER, CEILING STRUCTURE, AND BUILDING
To provide a sound absorber which can more effectively reduce noise to be transmitted from an upper floor to a lower floor, an adjustment method of the sound absorber, ceiling structure, and a building.SOLUTION: A box type sound absorber 1 is provided with an aperture 5 communicating with an air space A inside, of which the resonance frequency is adjusted to a frequency of a half-wavelength standing wave to be determined on the basis of dimensions of an indoor space R at a lower part of a ceiling space C.SELECTED DRAWING: Figure 1
【課題】上階から下階に伝わる騒音をより効果的に低減可能な吸音器、吸音器の調整方法、天井構造、及び建物を提供する。【解決手段】内部の空気層Ａに連通する開孔５が設けられた箱型の吸音器１であって、共鳴周波数が天井裏空間Ｃの下方の室内空間Ｒの寸法に基づいて決定される半波長定在波の周波数に調整されていることを特徴とする。【選択図】図１
