I really want to protect my house from external noise,to feel at ease. It can give a soundproofing of walls with own hands. The main thing is that the materials meet your needs and be of high quality. 
Sound insulation of a brick wall. It is almost impossible to make soundproofing of walls with the help of usual partitions. But today there are several ways to sound and noise insulation of walls. They will take a few centimeters from the total area of the entire room, but this will eventually justify itself. Consider the most popular methods of isolation.
Wall Preparation
Principle of soundproofing the walls. Before any soundproofing, you need to prepare the walls. We must free the room of all furniture, remove all the fixtures. Then remove the old wallpaper from the walls and carefully examine each wall. The existing cracks and holes should be well plastered and covered with a primer. Further we carry out soundproofing of all sockets, it is through them that very often strange sounds from neighbors are heard. To do this, first of all, you need to de-energize the room, untwist the outlet and gently remove it. The opening under the socket is filled with soundproofing material, for example, foam rubber, foam or fiberglass. We insert the socket and seal it in the wall with the help of alabaster or gypsum, we twist the lid. The same procedure is carried out with the installation boxes in which the wires are hidden. Best of all, if all work related to electricity, will be carried out by an expert. 
Sound insulation of the wall with mineral wool andplasterboard. Places connecting the heating pipes or water supply to the wall must be sealed with silicone or elastic sealant. The space near the pipe is cleaned from the old solution and closed with a new cement mortar. A place of joints, it is desirable to additionally seal with silicone sealant, so that when the temperature drops, do not allow the appearance of crevices on the solution. Carefully seal the joints between the walls, between the wall and the ceiling, between the wall and the floor. All detected voids can be eliminated with cement mortar or gypsum plaster. If necessary, close the gaps around the door frame and the window frames. Back to contents</a>
Use of soundproof panels
You can make soundproofing walls with the help ofmulti-layer panels, which consist of dense sheets and light layers of fiberglass or mineral wool. The peculiarity of such panels is that they can be mounted on walls without a frame. The thickness of such panels can be from 40 to 120 mm. The panels already have special holes through which they are fastened to the wall. There are also pazogrebnevye joints, which facilitate fixing. Preliminary on the walls with the help of acoustic sealant, glue two layers of a special gasket. Then proceed to the direct fastening of the panels. Do this from the bottom up using dowels. For additional strength, the grooves of the joints are tightened by screws. After the installation is completed, the joints of the panels are sanded with an emery cloth and we seal it with a sealant. After this, the panels can be plastered and proceed to the decorative finish. This method of noise isolation is considered quite simple and affordable. Back to contents</a>
Soundproofing based on carcass
Back to contents</a> Preparation of tools and material 
Tool for working with plasterboard. For this method, a pre-installation of the frame is required, on which the noise insulation material will be fixed. Then the entire structure is covered with plasterboard. Today this method is the most reliable. This is explained not only by the fastening, but also by the good circulation of air between the insulating material and the final finish. Disadvantages are considered to be the relative difficulty of fastening and taking more of the useful area of the room than in the case of gluing the material. There are two methods of wireframe soundproofing: on the basis of a wooden frame and metal. Working with metal is very similar to the structure of the frame from gypsum board. With a tree all is a bit more difficult, as there are no ready places for fastenings. It is more susceptible to deformation and requires good pretreatment for protection from pests and moisture. Therefore, we will consider in more detail the work with a metal frame. This noise insulation of the walls with their own hands is very reliable, as the lack of glue will ensure a longer service life of the panels and resistance to moisture and steam. To perform laborious work on the installation of the frame, you need to prepare the tools:

- building level and roulette;
- drill and screwdriver;
- sharp construction knife and hacksaw;
- a hammer;
- Furniture stapler;
- The container in which the glue will be mixed;
- set of screws;
- a simple pencil for markings;
- putty knife.
You still need to choose the material that will beused to noise insulation of the room. Basically, mineral wool is used, which absorbs all sounds well and is easily inserted into the frame. This is achieved by the air bubbles inside the material. Analogues of mineral wool can also be considered basalt slabs, which are also quite light and simple to install. 
The device of a metal skeleton under gypsum cardboard. The most budgetary and old variant of isolation of a premise from extraneous sounds it was long ago considered to consider trays from under eggs. Here we have in mind not plastic trays, but special paper trays, which were used since the Soviet era for the packaging of eggs. They absorb the sound very well, which was the reason for their installation, even in the premises for recording. However, fixing such material on the walls is a rather difficult and long work. And they are not particularly resistant to moisture. Before buying, measure all the walls well to determine the correct amount of material. It is always necessary to take it with a margin, in order to ensure the minimum distance between joints. This is extremely important, since in the process of thrusting the material into the frame there will be a significant contraction of the material. Back to contents</a> Mounting the frame to the wall 
The device of a wooden skeleton. So, first make a metal frame. It should be noted that this work requires a maximum level wall. Then everything will be much more reliable. How to prepare the wall, has already been described above. In general, this process is no different from the preparation of the wall before gluing the soundproof material. Now proceed to mount the frame. First, mark the wall. On the perimeter it is necessary to apply straight lines using the tape measure and pencil, where the guide profiles will be installed. Particular attention should be given to the corners. Correct and maximum tight connection of joints of horizontal and vertical bars will ensure good fixation of sound insulation. When the perimeter marking is complete, take the markings for the inner laths. Particular attention should be paid to the distance between them. It must always be remembered that the resulting space between the inner slats should be slightly smaller than the pieces of soundproof material that will fit there. You need to make metal squares. To do this, measure the dimensions of the insulation boards, take about 20-25 cm on each side. You will get the size of the squares. The wall should be noted in accordance with such dimensions. It often happens that you can not provide the same clear squares at the edges of the wall. Then you simply need to divide the remaining area into two or three parts. When the markings are made, proceed to fasten the frame. Mount is necessary from one end of the wall to the other. It is necessary to use self-tapping screws and screwdrivers. But, if the walls in the room are panel, one screwdriver can not do. You'll have to drill the wall with a puncher first, punch the dowels in the holes, and then attach the frame to the screws. The distance between the fasteners should be kept approximately 20 cm. Back to the table of contents</a> Fastening in the frame of insulating sheetsconcerns the installation of soundproofing plates, then everything is simple. The main thing is to be guided by simple rules, observance of which will make it possible to do everything as quickly as possible in a short time: 
Types of metal profile.
So after this you will only have to sewthe wall with plasterboard, seal the joints between the sheets and make the finishing with the desired method. When plating, you need to use a level so that the wall does not turn out to be a curve. During fixing, try to heat the screws of the screws so that they do not break the smoothness of the surface. When sealing joints, do not neglect the sufficient amount of putty. Features of soundproofing of walls with their own hands by frame and frameless methods are considered. Now you can easily get down to work. If you follow the above sequence of work and simple advice, then the insulation will be quite reliable and will protect the room from noise.
