In family decoration, most people hope to live with the elderly, children or nannies. In addition, the area of the house is not too large, and the sound insulation effect is particularly critical. However, the sound insulation index is a very professional number, which is not very effective only according to the merchant. Therefore, it is very practical to learn a little way to check the wooden door anacoustic.
The following three detection methods are the recommended detection methods of ordinary consumers, which are short and fast detection methods summarized according to the characteristics of wooden doors on the market.
1. Look at the weight
Anacoustic formula is directly related to the density of materials, 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. But note: adding sound insulation cotton in the middle of the flat hollow door will be more soundproof than solid wood door.
2. Look at the thickness of the wooden facade laminate
The thicker the surface layer board, the better the sound insulation effect. Generally, the surface plate of wooden door should be 8mm thick. The thickness of the surface layer is also better, but the cost will increase. But: The surface sheet of the iron plate fire door is 3mm thick, and the sound insulation effect is also good.
3. Look at the flatness of wooden doors
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.
Note: In fact, the sound insulation of doors and windows industry has the same national grade as fire doors, rather than a single definition of a certain content. The concepts of "sound insulation" and "sound absorption. Anacoustic the principle depends on the quality or the density of the material (when the overall weight of the iron plate door is less than that of the wooden door per unit area, its sound insulation is not as good as that of the wooden door), the sound absorption depends on the fine surface area and uneven surface space of the material (rock wool, mineral wool, and foam are all acoustical material rather than sound insulation materials)
