SOUNDPROOF UNIT
To provide a soundproof unit for effectively reducing noise in an elevated structure having an opening.SOLUTION: A soundproof unit 1 installed below an opening part penetrating an elevated structure in the vertical direction is provided with a cylindrical wall part 2 having a cylindrical middle part communicating with the opening part and projecting downward and a soundproof member 3 arranged at the lower end of the cylindrical wall part 2; the soundproof member 3 is provided with a sound-insulating plate part 4 of an inclined plate shape directed to the inside of the opening part as it goes downward, the tip of the sound-insulating plate part 4 is arranged lower than the lower end of the cylindrical wall part 2, and sound-absorbing materials 51, 52 are arranged at positions on the opposite side of the opening part to the sound-insulating plate part 4. Since the sound-absorbing materials 51, 52 are arranged at a position on the opposite side of the opening part with respect to the sound-insulating plate part 4 whose tip is arranged at a lower position, the noise diffracted at the position of the tip of the sound -insulating plate part 4 is attenuated, and the noise passing through the cylindrical wall part 2 is less likely to reache a far distance.SELECTED DRAWING: Figure 5
【課題】開口部を有する高架構造物において騒音を効果的に低減する防音ユニットを提供する。【解決手段】高架構造物を上下方向に貫通する開口部の下方に設置する防音ユニット1であって、筒中部分が前記開口部へ連通し下方へ突出する筒状の筒壁部２と、この筒壁部２の下端に配置する防音部材３を備え、前記防音部材３に、下方へ至るほど前記開口部の内側へ向かう傾斜板状の遮音板部４を備えさせると共に、この遮音板部４の先端を前記筒壁部２の下端より下方に配置させ、前記遮音板部４に対して前記開口部の逆側の位置に吸音材５１、５２を配置する。先端をより低い位置に配置させた遮音板部４に対して前記開口部の逆側の位置に吸音材５１、５２を配置させるので、遮音板部４の先端の位置で回折した騒音が減衰されて、前記筒壁部２を通過する騒音が遠方へ届きにくくなされる。【選択図】図５
