In home life, if you want to give yourself a comfortable and quiet rest space, then sound insulation is very important. In general, everyone will think that when the door is closed, it will be sound insulation, this depends on the sound insulation effect of wooden doors, so what door has good sound insulation effect? The following website gives you a detailed introduction to the selection skills of soundproof wooden doors.
Each door has a certain sound insulation effect, but the effect varies greatly. According to relevant national regulations, the sound insulation effect of bedroom door should reach 22 to 25 decibels. In terms of the materials used in bedroom door, the sound insulation performance of solid wood door and solid wood composite door is much better than that of paint-free door, steel wooden door and mould door. From the difference of the door, the sound insulation and sealing effect of T-shaped door (German door) is better than that of traditional flat door.
Door partition no sound insulation in addition to the sealing after the door is closed, the quality of the door panel is also very important. The sound insulation effect of the door panel mainly depends on the filling of the inner core of the door. Generally speaking, the molded soundproof door inner core is filled with cellular structure paper base, and the sealed air layer formed by it can play a very good sound insulation role. However, the inferior door panel only uses cardboard to make several partitions in hollow-core, and the sound insulation effect is very poor. In addition, the door with particleboard used in the inner core has better sound insulation performance, and the sound insulation effect can reach 32 decibels. In addition to the inner filler of the door, for solid wood door and solid wood composite door, the higher the density of the wood itself, the heavier the weight, and the thicker the door plate, the better the sound insulation effect.
The sound insulation effect of plastic steel door depends on the thickness and type of glass. Carved glass doors and double hollow glass doors have the best sound insulation effect, which is suitable for the partition between bedroom, study or kitchen and living room. Even if the quality is soundproof door, it needs to be installed tightly, and poor installation will affect the sound insulation effect. Therefore, we recommend that professionals install doors and door set.
Sound insulation wooden door selection skills:
1. Depending on the weight, the anacoustic formula is directly related to the density of the material, so the sound insulation with high density is relatively good, and the mould door is relatively light, which is the root of the poor sound insulation of mould door.
2. Look at the thickness of the wooden facade laminate, the thicker the facade laminate, the better the sound insulation effect. The surface laminate of wooden door is 8mm thick, which is rare in the wooden door industry. The thickness of the surface layer is also better, but the cost will increase.
3. Look at the flatness of the wooden door. The flatter the wooden door, the better the combination with door set, no matter what the structure is. As long as the deformed wooden door is soundproof, it will definitely not work, air leakage.
There is also a little professional, door set the quality of the expansion glue between the wall, which will seriously affect the sound insulation if it is not good.
In order to avoid the impact of noise on people's health and create an indoor green sound environment, T-shaped gate has gradually become the protector for people to stay away from noise.
Green sound insulation standard?? 25 dB
when people buy home doors, they often 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, sound insulation is the primary standard. The sound insulation standard index for interior home doors in China is 22 to 25 decibels, that is, the doors should resist at least 20 decibels of noise. But calculate the car engine sound, the high-frequency stereo sound of various indoor electrical appliances, the next-door neighbor singing karaoke, the kitchen (kitchen decoration effect diagram) range hood, refrigerator, air conditioner...... Noise is everywhere, and ordinary doors are already overwhelmed. Many families endure the pollution caused by noise day and night, which makes people restless and seriously affects their normal life. The soundproof door represented by T-shaped door can resist at least 40 decibels of noise, ensure the indoor green sound environment and return you a quiet home.
T-shaped plug-soundproof door revolution
the so-called T-shaped door is that 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 door. The traditional Pingkou gate still occupies a dominant position in our country. The T-shaped gate is only in the promotion period, while the T-shaped gate has been popular in Europe for more than 20 years. The sound insulation effect of T-shaped door can be several times higher than that of flat door. The main reason is T-shaped technical structure and internal sound absorption material.
Double trisquare structure
the T-type structure makes the door panel and the door frame form a double trisquare seam, and the bite is tight. Compared with the flat door, the door seam is smaller and the sound blocking ability is stronger. The author personally tested and listened behind the flat Gate and the T-shaped plug Gate respectively. He found that the latter could effectively block the noise outside the door. It was also the conversation between the two. After the flat gate, he could still hear some words clearly, and T-shaped plug behind the door, you can't hear any sound. In addition, the door of this structure uses rubber sealing strip at the joint, because the rubber has strong elasticity and sound insulation. The sound measurement report of German rubber seals used in T-shaped doors usually squeeze the rubber seals to a thickness of about 5mm when closing doors, and the sound insulation effect at this time has reached 50 decibels, exceeds national standards.
Three-layer sound insulation effect is remarkable
t-shaped door is generally divided into three layers. The outside is two high-density solid wood boards, and the middle is a wood particle layer similar to particleboard. At the same time, air holes are arranged neatly, which has sound insulation and heat preservation effects, this kind of door core is both environmentally friendly and soundproof about 30 decibels. When the noise sound wave comes, the high-density solid wood first resists the noise of the reflected part, the middle layer absorbs the part with strong penetration, and the solid wood boards on the other side continues to block, thus ensuring the minimum noise penetration.
The size of the door seam is standard.
The website reminds that there are relevant requirements in the industry standards of wooden doors regarding how many seams are left. Generally speaking, the gap between the door and the ground should be between 5-8mm, the gap between the left and right of the door and the door frame should not be more than 6mm, and the gap between the upper side of the door should not exceed 2mm. The gap is too large, which not only affects the appearance, but also affects the sound insulation effect. In winter, the inlet wind does not keep warm. Of course, the gap is too small. The wooden door is dry shrink and wet, and it will deform when it is wet in summer, it will cause the situation that it is not easy to switch. You can take a scale to measure the size of the door crack to see if it is compliant.
Sound insulation non-definable targets
as for the sound insulation effect of wooden doors, Chen Huimin pointed out that there is no anacoustic about definable targets in the current wooden door industry standard, unless it is a special soundproof door. Generally speaking, consumers can achieve the sound insulation effect required by normal living room as long as they buy qualified wooden door products with high prices and above.
In addition, the sound insulation performance of wooden doors is also related to materials. Generally speaking, the higher the material density, the stronger the sound insulation performance. If the dragon skeleton in the wooden door is very loose and the two door panels on the surface are also thin, the sound insulation performance of this kind of wooden door is relatively poor. In addition, the sealing strip of the wooden door is not tightly fitted and the upper and lower seams of the door are too large, which will also affect the sound insulation performance of the wooden door.
