To provide a soundproof device which can improve sound insulation performance while suppressing increase in cost.SOLUTION: A soundproof device 1 for suppressing propagation of sound to outdoor from a louver 4 of a building 2 includes: an upper ventilation passage 10 and a lower ventilation passage 20 which are provided on the indoor of the building 2, and constitute a ventilation passage of air supplied to indoor through the louver 4 from the outdoor; a sound absorption part 30 which is provided on the ventilation passage and is configured to absorb sound; and a reflection part 40 which is provided on the ventilation passage, and reflects the sound moving toward the louver 4 and guides the sound to the sound absorption part 30.SELECTED DRAWING: Figure 1
【課題】コストの増大を抑制しつつ、遮音性能の向上を図ることができる防音装置を提供する。【解決手段】建物２のガラリ４から屋外への音の伝搬を抑制するための防音装置１であって、建物２の屋内に設けられ、屋外からガラリ４を介して屋内に給気される空気の通気路を構成する通気路上部１０及び通気路下部２０と、前記通気路に設けられ、吸音可能に構成された吸音部３０と、前記通気路に設けられ、ガラリ４に向かって移動する音を反射させて吸音部３０に誘導する反射部４０と、を具備する。【選択図】図１
