High-rise residential building noise control system
Technical Field
The invention relates to the technical field of noise prevention, in particular to a high-rise residential building noise prevention system.
Background
The high-rise building refers to a residential building with the building height of more than 27m and a non-single-storey factory building, a warehouse and other civil buildings with the building height of more than 24m, and at the present stage, most of the residential buildings are high-rise buildings.
When the high-rise building is used, due to the fact that surrounding shelters are few, when the building is arranged close to the road side, particularly close to a main road, the noise of the road is large, and obstacles met by the noise in the transmission process are few, so that the sound volume is large, the life of residents is affected, and most of high-rise wind noise is generated at the present stage due to the fact that the sealing effect of a window body is poor and the sealing position of the window body is vibrated.
