In home decoration, most owners want to live with the elderly, children or nannies, plus the size of the house is not too big, the sound insulation effect is particularly critical. However, the sound insulation index is a very professional number. It is not too big for the merchants to say, so it is very practical to learn a way to check the sound insulation of the wooden door. Here are three tips for reference:
1. Look at the weight, the formula of the sound insulation is directly related to the density of the material, so the sound insulation with high density is relatively good, and the molded door is relatively light, which is the source of poor sound insulation of the molded door.
2. Look at the thickness of the wooden facade laminate. The thicker the laminate, the better the sound insulation effect. The TATA wooden door panels are 8mm thick, which is rare in the wood door industry. The thickness of the surface layer is also good, but the cost is increased.
3, look at the flatness of the wooden door, the flatter the wooden door, the better the combination of the same door cover, regardless of the structure. As long as the deformation of the wooden door is not soundproof, it will leak.
There is also a slightly more professional, the quality of the expansion glue between the door cover and the wall. If this is not good, it will seriously affect the sound insulation.
In order to avoid the impact of noise on people's health and create an indoor green sound environment, the T-type door has gradually become a protector of people away from noise.
Green soundproofing standard - 25 decibels
When people buy home doors, they tend to pay more attention to the materials and styles of the doors. In fact, the sound insulation function of the door is much more important than the modeling style. To measure the quality of the door, the sound insulation is the primary standard. The sound insulation standard index for indoor homes in China is 22 to 25 decibels, that is, the door should resist at least 20 decibels of noise. But the calculation of car engine sound, high-frequency stereo sound of various electrical appliances in the room, neighboring singer karaoke, kitchen range hood, refrigerator, air conditioner... noise is everywhere, the general door is already overwhelmed. Many families endure day and night pollution caused by noise, making people emotionally upset and seriously affecting normal life. The soundproof door represented by the T-shaped door can withstand at least 40 decibels of noise, ensuring a green indoor environment and a quiet home.
T-port - the revolution of the soundproof door
The so-called T-shaped door, that is, the door panel looks like a capital letter T from above, which is named after the traditional flat door. Because it is produced in Germany, it can also be called German-style door. In China's traditional flat door still dominates, the T-port is only in the promotion period, and the T-port has been popular in Europe for more than 20 years. The sound insulation effect of the T-type door can be several times higher than that of the flat door. The main reason is the T-shaped technical structure and the internal sound absorbing material.
Double-curve structure
The T-shaped structure forms a double-curved joint between the door panel and the door frame, and the bite is tight. Compared with the flat door, the door seam is smaller, and the ability to block the sound from penetrating the seam is stronger. The author personally experimented and stood in the flat door and the T-shaped door, and found that the latter can effectively block the noise outside the door. It is also the conversation between the two people. It is still after the flat door.
In order to hear the individual words, the T-type mouth can not hear any sound. In addition, the door of this structure uses a rubber sealing strip at the seam because the rubber has strong stretchability and sound insulation. The sound report of the German rubber seal used in the T-port is that the rubber seal is usually squeezed to a thickness of about 5 mm when the door is closed, and the sound insulation effect has reached 50 decibels, exceeding the national standard.
Three layers of sound insulation are remarkable
The T-port door is divided into three layers. The exterior is two high-density solid wood panels. The middle is a wood particle layer similar to the particle board. At the same time, the air holes are arranged neatly, which has sound insulation and heat preservation effect. The door core is environmentally friendly and capable. Sound insulation is about 30 decibels. When the noise sound waves come, the high-density solid wood first resists the reflected part of the noise, the middle layer absorbs the penetrating part, and the other side of the solid wood board continues to block, thus ensuring the minimum noise penetration.
