How to test the sound insulation of wooden doors

Sound insulation index is a very professional number, only rely on the business said, the role is not too big, so learning a little bit to check the sound insulation of wooden doors is very practical.

The following three detection methods are recommended by 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. The formula of sound insulation is directly related to the density of materials. Therefore, the sound insulation with high density is relatively better, and the molded door is relatively light. This is the root cause of poor sound insulation of molded doors. But note: flat hollow doors with sound insulation cotton in the middle will be more sound insulation than solid wood doors.

2. Look at the thickness of the wood door veneer. The thicker the laminate, the better the sound insulation effect. Generally, the veneer of wooden door should be 8mm thick. At the same time, the thickness of the surface layer is better, but the cost will increase. However: the surface layer of the iron plate fireproof door is 3mm thick, and the sound insulation effect is also good.

3. Look at the flatness of the wooden door. The smoother the wooden door, the better the combination with the door cover, regardless of the structure. As long as the deformation of the wooden door sound insulation is certainly not good, air leakage.

There is a little bit more professional, the quality of the expansion glue between the door pocket and the wall, if this is not good, it will seriously affect the sound insulation.

Note: as a matter of fact, the sound insulation of doors and windows industry is of national level, not defined by a single content. About the concept of "sound insulation" and "sound absorption". The principle of sound insulation is determined by the quality or the density of material. The sound insulation of a door is less than that of a wooden door. The sound absorption depends on the surface area and uneven surface space of the material (rock wool, mineral wool and foam are sound absorbing materials, not sound insulation materials).
