The walls of the premises are designed not only to distinguish between rooms for their functional purpose, but also to carry out obstacles to the spread of sound. All walls can be divided into two types: single -layer (which are built of stone, brick, etc. D.) and multi -layer (combine several building materials and form from several layers). The former are better missing sound waves, others are worse. To improve sound insulation, you can use one of the following options. The first option is to make the wall massive or quite stiff. So, the sound wave will not be able to inflict a barrier (wall) of oscillations. The heavy wall has less vibration, and therefore, sound insulation is the best. By the way, the cost of the frame house is much growing if the walls are sounded there. After all, it is not a pity to give the palatine more money, but to live in peace.
The second option provides for the creation of conditions under which the sound penetrates the wall and is scattered there. Such a plan can be implemented thanks to the construction of walls from fibrous or porous materials.
The multilayer wall consists of several sheets, between which there is also the air part. The plasterboard partition with a thickness of 150mm and the air layer inside has a sound insulation of 52 dB. This is a good enough indicator that makes it possible to enjoy silence.
If additional soundproofing is required, then a layer of mineral wool or fiberglass plate can be placed in a multilayer wall.
