SOUND INSULATION SHEET AND SOUND INSULATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a sound insulation sheet capable of improving sound insulation performance by exceeding a mass law.SOLUTION: In a sheet 11 fixable to an adherend 2, in a sound insulation sheet 1, when fixing the sheet 11 and the adherend 2, two or more independent space parts 3 can be formed between the sheet 11 and the adherend 2, and an acoustic intensity level (LI) in 4000 Hz when fixing the sheet 11 and the adherend 2 so that the space part 3 is formed between the sheet 11 and the adherend 2 and an acoustic intensity level (LI) in 4000 Hz when fixing the sheet 11 and the adherend 2 so that the space part is not formed, satisfy a condition indicated by the following mathematical expression (F1). LI-LI≥1 dB ...(F1).SELECTED DRAWING: Figure 3
【課題】質量則を超えて遮音性を向上できる遮音シートを提供すること。【解決手段】被着体２に固定できるシート１１であって、シート１１と被着体２とを固定した際に、シート１１と被着体２との間に独立した空間部３を２つ以上形成でき、シート１１と被着体２とを、シート１１と被着体２との間に空間部３が形成するように固定した場合の４０００Ｈｚにおける音響インテンシティレベル（ＬＩＯ）と、シート１１と被着体２とを、前記空間部が形成されないように固定した場合の４０００Ｈｚにおける音響インテンシティレベル（ＬＩＮ）とが、下記数式（Ｆ１）で示される条件を満たす遮音シート１。ＬＩＯ−ＬＩＮ≧１ｄＢ ・・・（Ｆ１）【選択図】図３
