The present invention aims to provide a sound insulating device that exerts excellent sound insulating property, the sound insulating device capable of maintaining the sound insulating property over a long period, excelling in assembly workability, and being simply manufactured and readily disposed. In the sound insulating device, a long sound insulating member including a polyhedron body bent at a predetermined angle to open a sound source side is sequentially stacked between supporting columns arranged in an upstanding manner at a predetermined spacing to configure a sound insulating wall 10 having an appropriate height; and sound wave from the sound source is interfered with each other by the polyhedron body to reduce noise.

La présente invention concerne un dispositif antibruit qui présente d'excellentes caractéristiques antibruit. Le dispositif permet de conserver les caractéristiques antibruit pendant longtemps, présente une excellente capacité de montage et peut se placer facilement. Dans le dispositif antibruit, chaque long élément antibruit (11) possède un polyèdre (12) courbé selon des angles prédéterminés et ouverts du côté de la source sonore, et une paroi antibruit (10) d'une hauteur appropriée est construite en déposant séquentiellement chaque élément antibruit (11) les uns sur les autres entre des supports (30) érigés à des intervalles prédéterminés. Les polyèdres (12) permettent aux ondes sonores, entrant dans le dispositif depuis la source sonore, d'interférer entre elles et de réduire ainsi le bruit.
