What material is good for sound insulation of movable partition?
The inspection method of sound insulation effect is to play music normally in a room, and measure the sound attenuation degree at one meter from the door. For example, the sound pressure level in the room is 90dB, and the sound pressure level measured at one meter outside the room is 60dB, which means the sound insulation is 30dB. The treatment of the door of the room is also a more difficult problem in the decoration design. The processing of the door of the recording studio is professional, and the sound insulation effect is very good, but the cost is very high. Generally, the price of a sound insulation door is as low as 4000 to 5000 yuan, and more than 10000 yuan. At present, the more practical method is to use the molding integrated door and add seal on the side of the door. The sound insulation effect of the door closer is good.
The first choice is sound insulation wallboard, which belongs to professional sound insulation material. There are metal plates on both sides and foam plastic with sound insulation effect in the middle. The greater the thickness of the wall panel, the better the sound insulation effect. In some places, due to the problem of bearing weight, brick walls or other methods of building walls can not be used, only the method of light steel keel gypsum board can be used.
Secondly, economic and practical is 2 / 4 red brick wall, both sides of the cement wall. This kind of partition wall must be built to the top. When it needs to go through the ventilation pipe or other lines, the sealing problem of the pipeline should be paid attention to, otherwise it can also cause crosstalk.
It is also possible to add a layer of cement board with high hardness outside the gypsum board. The appearance of the cement board is the same as that of the gypsum board (the size is similar), but the hardness is far higher than that of the gypsum board, which is a good sound insulation material. Attention should be paid to the construction technology problems, especially the gap part must be sealed.
