Abstract

PURPOSE: To reduce the noise level by forming, on at least one surface plate of a door, a three-dimensional louver having upward cut ends protruding to the interior of the surface plate, and allowing both the surface plates to pinch therebetween a sound absorbing material with a cloth material attached to the surface thereof. CONSTITUTION: The objective door 5 is constructed by joining surface plates 8 each having a louver 7 on both surfaces of a peripheral frame 6, and allowing the surface plates 8 to pinch a sound absorbing material 9 therebetween. The louver 7 has horizontally extruding upward cut ends 71 which protrude to an inner side 84 of each surface plate 8, and downward ventholes 74 which each open at multiple stages. The material 9 is formed by attaching a cloth material to the surface of a thick sheet made of glass wool or the like, and prevented from coming in contact with the surface plate. Voice or the like let out in the front of the surface plate 8 is propagated from the ventholes 74 to the interior of the surface plate 8, to be absorbed by the material 9. Accordingly, the noise level in a room can be reduced.
