When consumers choose home wooden doors, they tend to pay more attention to the material, design and style of the door. In fact, the sound insulation function of the door is much more important than the style and style. Sound insulation is an important standard to ensure safe privacy.
There are many factors that affect the sound insulation performance of wooden doors. Under normal circumstances, if it is a solid wooden door, the door with higher density of solid wood material has better sound insulation effect. The sound insulation effect of the flat hollow door is better than that of the solid wood door, and its sound insulation effect mainly depends on the filling of the inner core of the door.
In general, the inner core of the molded soundproof door is filled with a paper base of a honeycomb structure, and the closed air layer formed by the core can provide a good sound insulation effect. According to Wang Chunmei, manager of RATA's R&D department, the fillers used in the common wooden doors on the market are mostly dense, and the use of bridge mechanics not only has the advantages of stronger structural stability and easy cutting, but also its sealing and resistance. Pressure and bending resistance are also better, and other functions are enhanced while ensuring sound insulation.
From the perspective of the door panel structure, the wooden door of the T-shaped structure has better sound insulation effect. The so-called T-port is named after the traditional flat door. The sound insulation effect of the T-shaped door is several times higher than that of the ordinary flat door. The reporter learned that this is because the T-shaped structure makes the door panel and the door frame form a double-curved joint, and the bite is tight, which is smaller than the flat door door and blocks the sound. The ability to penetrate seams is stronger.
In order to further improve the sound insulation effect, some enterprises use rubber sealing strips or magnetic strips at the joints of the doors to make the joints of the door and the door frame more tight to reduce noise.
In addition to this, the sound insulation effect of the door is related to the installation in addition to the door itself. For example, the reserved space before installation should not be too large. Generally, a gap of 3 mm is left on both sides and above.
