Assembled partitionWall PanelIs a new type of contemporary energy-saving environmental protection wallboard materials.Assembled partition wall panelIt has male and female slots. During the installation process, only the wall panels need to be erected to connect the male and female card slots, and a small amount of sand and dust is applied to connect them together. So...Assembled partition wall panelIs the sound insulation good? belowAssembled partition wall panelManufacturerwill provide you with answers.

ImpactAssembled partition wall panelThe factors of sound insulation effect are:

1. The law of mass: The universal law of wall sound insulation is the surface density of the material. The greater the surface density, the better the sound insulation effect. Compared with a single-layer solid wall, whenever the surface density is doubled, the sound insulation capacity will theoretically increase by 6Db. This law is the law of mass. For the double layerAssembled partition wall panelThe law of mass plays a more important role.

2. Resonant frequency: All partitions have a resonant frequency. When the frequency of the sound wave and the resonance frequency of the wall reach the same level, the wall will resonate, and the sound insulation of this frequency will be greatly reduced.

3. coincidence effect: acoustic contactAssembled partition wall panelAfter that, in addition to the forced vibration in the vertical direction, the wall panel also produces forced bending vibration along the surface of the panel. At a certain frequency, the forced bending vibration will be consistent with the inherent free bending vibration of the board, and the wall board will bend gently with the incident sound, resulting in a large amount of sound energy penetrating to the other side, thereby forming sound. The violent coincidence effect of the double-layer board is particularly obvious.

4. Sound bridge: The strong rigid connection between the double-walled air layer should be avoided as much as possible. If there is an acoustic bridge, it will destroy the elastic layer effect of the air layer and reduce the sound insulation capacity. When the plate is fixed to the keel, the vibration of the side plate that receives the sound will be transmitted to the other side plate through the keel. This phenomenon of transmitting acoustic energy like a bridge is called an acoustic bridge. The more sound bridges, the larger the contact area, the stronger the rigid connection, and the worse the sound insulation effect. Adding elastic pads between the wood board and the keel, elastic metal strips and elastic material pads have some room for improvement in the sound insulation of the wallboard.

5. Panel joints and holes: If there are joints and holes in the partition wall, the sound insulation of the partition wall will be affected. Usually, plastic elastic strips are inserted when the keel is installed around the wall. The two-layer composite sound insulation board should be installed in the form of staggered seams, otherwise the sound insulation capacity will be reduced.
