description The utility model relates to a silencing device for building ventilation, which comprises a building main body, a mounting rack is fixedly connected to the outer wall of one side of the building main body, a case is mounted on the outer wall of the top of the mounting rack, an extension frame is slidably mounted on the case, and a shutter frame is mounted on one side, far away from a storage groove, of the extension frame. A positioning assembly is arranged on the machine box and used for fixing the position of the extending frame, and a silencing assembly is arranged in the machine box. According to the noise reduction device, the noise reduction assembly is arranged, when the draught fan in the machine box is started, the noise generated during operation of the draught fan is absorbed through the noise reduction assembly, and then the effect of reducing the noise is achieved. 本实用新型涉及一种建筑物通风的消声装置，包括建筑主体，所述建筑主体的一侧外壁固定连接有安装架，所述安装架的顶部外壁安装有机箱，所述机箱上滑动安装有延伸框，所述延伸框远离收纳槽的一侧安装有百叶框，所述机箱上设置有定位组件，所述定位组件用于对延伸框的位置进行固定，所述机
