Sound insulation - is the decoration in the room walls, floor and ceiling with special materials that can absorb noise and provide the desired level of silence.
Sound insulation in the apartment is not less important than thermal insulation. It is proved that loud noises, which do not give rest, have a very negative effect on the human psyche, causing nervous disorders, psychoses, failures and depressive state. Making sound insulation by one's own hands is not so difficult as it might seem, you will not need super-expensive tools and materials for your work. A little effort to prepare the room and adhere to all the stages of work, and problems in the form of sound tires from the roadway, annoying playing the violin of a neighbor's girl and the old man's TV turned on at full volume will disappear forever. And you yourself will not allow neighbors to scold you for stormy viewing of football with friends, for barking your favorite dog and music of the most unexpected style, no matter how loud it may be. Sound insulation of the walls is the main stage of the work, followed by the finishing of the floor and ceiling, it must be carried out carefully, without fuss, because haste can lead to defects in work and poor sound insulation of the premises, and accordingly a waste of finance.
Sound insulation in the apartment with their own hands
Noise types and permissible norms
Noise is subdivided into air, impact and structural noise. The first include screams, laughter, loud conversation, that is, those sounds that penetrate through the cracks, doors, windows. The second - the work of a puncher, and to the third, all the noise transmitted through vibrations.
The noise level is measured in decibels. The human whisper is 20 dB, a quiet conversation is 40 dB, the acceptable noise level at the enterprise is 85 dB, but a sound with a strength of 130 dB causes physically unpleasant sensations. Measure the noise level to find the material with the required degree of sound insulation.
Kinds of the most popular soundproof materials
- fiberglass;
- foam polyethylene( with poor waterproofing on this material develops mold);
- elastomeric plates and gaskets;
- cork-rubber substrate( as well as polyethylene foam is prone to mold);
- bitumen-cork substrate( additional to sound insulation quality - waterproofing);
- extruded polystyrene foam, for example Isoplat ISOPLAAT and Isotex ISOTEX( has a good level of noise insulation and insufficient level of noise absorption).
When choosing a material, pay attention not only to the cost and ease of installation, but also to the environmentally friendly, non-toxic soundproof layer.
Self-preparation room
Preparing the premises for work. The first thing to do is to remove all existing furniture, cornices, chandeliers from the room, remove old wallpaper and plaster. The walls should be as level as possible, with a difference of not more than one centimeter. To do this, carefully inspect and repair the plaster( gypsum or cement mortar), existing cracks, gaps in the sockets and the door frame, and then completely plaster the wall, level it with a long spatula, the dried walls are scraped with irregular mesh or coarse wool. Places connecting the heating pipes with the wall must be sealed with a sealant based on silicone. This is done to exclude the appearance of gaps during periods of seasonal temperature differences.
Sound insulation of walls with own hands
Stages of fastening of aluminum profiles:
- - we do marking with a pencil on the ceiling, using the laser level;
- - we put on lighthouses;
- - lay soundproof tape under the guiding profile;
- - we fix the profile guides to the floor, ceiling and along the edges, fastening them together with self-tapping screws for metal;
Fastening the metal profile to the wall
- - install the rack profiles at a distance of 60 cm from each other, check the level and apply a soundproof tape.
Installation of rack profiles
Installation under the frame of insulating material
Pre-selected type of insulation material is installed inside the metal frame so that there are no gaps and voids. It is desirable to install the device in a respirator and rubber gloves to protect the skin and respiratory tract from irritating particles of the soundproof layer.
Installation of soundproof material between the walls 
Installation under the frame of the soundproof layer Sheathing of the metal frame with gypsum board
- glue the entire surface of the profiles with soundproof tape;
- sheets of gypsum board( GKL) are attached to the frame with screws 25 mm in length;
Sheathing of metal frame by gypsum board
joints - crevice between gypsum cardboard and walls, ceiling, floor sealant.
- we ground the surface of sheets of gypsum board before the subsequent facing( pasting).
The easiest way to install soundproofing on walls is to use ready-made ZIPS panels that are fastened without a frame base. The disadvantage is not the low cost of the panels. The system consists of sheets of gypsum board and sandwich panels, which in turn have two layers - GVL( gypsum fiber) and staple glass fiber.

Assembly:
- leveling and plastering walls;
- sealant glue to the floor and ceiling two layers of soundproof tape;
- we cut the panels and mount them through the vibro nodes;
- after assembly joints are treated with a sealant.
In addition to the above methods, sometimes soundproofing is produced by unconventional methods. For example, as a sound-proof material of factory production, cardboard egg gratings or a password are used. Saving on this, of course, will succeed, but the quality is unlikely to be good enough.
