SOUNDPROOF UNIT
To provide a soundproof unit capable of effectively damping noise passing through the unit and noise passing upward.SOLUTION: A soundproof unit comprises: an inclined plate part having a front inclined plate and a rear inclined plate that project in an inclined manner upwardly of the front side and the rear side respectively; and a sound insulation plate part having a front side sound insulation plate and a rear side sound insulation plate arranged at intervals longitudinally. The front inclined plate and the rear inclined plate are arranged in a substantially V-shape. The sound insulation plate and the inclined plate part are provided so as to form a cylindrical wall of a cylindrical body. The noise from a front sound source side is blocked by the front inclined plate, so that the sound is dampened, and the noise diffracted at the position of the front end is dampened so as to enter between the front inclined plate and the rear inclined plate. Further, since the sound insulation plate part and the inclined plate part are provided so as to form a cylindrical wall of the cylindrical body, the rigidity of each sound insulation plate is improved, and the sound insulation effect of the sound insulation plate part is improved.SELECTED DRAWING: Figure 5
【課題】ユニット内を通過する騒音と上方を通る騒音とを効果的に減衰できる防音ユニットを提供する。【解決手段】前側の上方と後側の上方へそれぞれ傾斜状に突出する前側傾斜板及び後側傾斜板を有する傾斜板部と、前後に間隔をあけて配置される前側遮音板及び後側遮音板を備える遮音板部を備えさせ、前側傾斜板と後側傾斜板を略Ｖ字形状に配置させ、前記遮音板と傾斜板部が筒状体の筒壁を構成するように設ける。前方の音源側からの騒音は前側傾斜板に遮られて遮音されると共に、その先端の位置で回折した騒音が前側傾斜板と後側傾斜板の間に入り込むようにして減衰される。また、前記遮音板部及び傾斜板部で筒状体の筒壁を構成するように設けるので、各遮音板の剛性が向上し、遮音板部における遮音効果が向上する。【選択図】 図５
