SOUND INSULATION STRUCTURE BODY
PROBLEM TO BE SOLVED: To provide a sound insulation structure body 1 capable of exhibiting sound insulation effect over a wide frequency range from a lower frequency to a high frequency.SOLUTION: A sound insulation structure body 1 includes a plate-like body 2, a bag body 3 as a press body which comes into partial or entire contact with an inner surface 20 of the plate-like body 2 to apply pressure, and a net body 4 serving as a retainer arranged opposite to the plate-like body 2 across the bag body 3. The net body 4 retains the bag body 3 at a predetermined position against reaction force as the bag body 3 presses the plate-like body 2. The net body 4 has a plurality of through holes. The bag body 3 presses the plate-like body 2 with pressure of a gas charged to the inside. The bag body 3 presses the plate-like body 2 and then gives the plate-like body 2 rigidity for exhibiting sound insulation performed at least in a frequency range of 10-40 Hz.SELECTED DRAWING: Figure 1
【課題】 低周波から高周波まで幅広い周波数領域に対する遮音効果を発揮することができる遮音構造体１を提供する。【解決手段】 遮音構造体１は、板状体２と、板状体２の内面２０の一部または全部に接触して加圧する加圧体としての袋体３と、袋体３を挟んで板状体２と対向して配置された保持体としての網体４と、を含む。網体４は、袋体３が板状体４を加圧した反力に抗して袋体３を所定位置に保持する。網体４は、複数の貫通孔を有する。袋体３は、内部に封入された気体の圧力によって板状体２を加圧する。袋体３が板状体２を加圧することで、少なくとも１０Ｈｚ〜４０Ｈｚの周波数領域における遮音性能を発揮する剛性を板状体２に付与する。【選択図】図１
