To provide a sound arrester that is easy to install at a rental house or a wooden apartment, easy to air-condition or ventilate a space for which sound is insulated, inexpensive, and readily installable.SOLUTION: A sound arrester 2 includes: a plurality of shield members 51; a holding part composed of two support members 54a, 54c vertical to a floor surface of a floor 10, the support members holding a plurality of shield members 51a-51e at a predetermined interval, and two support members 54b, 54d parallel to the floor surface of the floor; and flow channel deforming members 57b-57d formed between adjacent two shield members and deforming a flow channel through which air flows. In the flow channel, a flow channel outlet 58c through which air flows out has an area formed to be smaller than that of a flow channel inlet 58a through which air flows in, and the area of a flow channel inner part 58b is deformed to be smaller than the area of the flow channel inlet 58a by the flow channel deforming members.SELECTED DRAWING: Figure 7
【課題】賃貸住宅や木造アパートに設置しやすく、防音される空間の空調又は換気を行うことが容易で、費用が嵩まず、手軽に設置可能な防音装置提供する。【解決手段】防音装置２は、複数の遮蔽部材５１と、複数の遮蔽部材５１ａ～５１ｅを、所定の間隔を空けて保持する、床１０の床面に対して垂直な２本の支持部材５４ａ～と、床の床面に対して平行な２本の支持部材５４ｂ～により構成される保持部と、隣接する２つの遮蔽部材の間に形成され、空気が流れる流路を変形する流路変形部材５７ｂ～５７ｄと、を備える。流路は、空気が流入する流路入口５８ａより、空気が流出する流路出口５８ｃの面積が小さく形成され、かつ、流路変形部材により、流路内部５８ｂの面積が流路入口５８ａの面積より小さく変形される。【選択図】図７
