One of the problems of high-rise buildings is noise. That is why residents of city apartments make soundproofing. This event is quite expensive if you order it from professionals. But with a basic knowledge of noise and vibration and a minimum of building skills, you can inexpensively isolate a room from excessive noise from your neighbors.
Where does the noise come from
Insulating a room does not start with the purchase of materials or installation work. First you need to find out what type and in what direction the noise source is located. Here it is necessary to determine as clearly as possible: it is necessary that the sound does not enter the room or that it does not go outside the premises. Also, perhaps the question is much more global. That is, complete soundproofing of the room. It is on these conditions that the complexity of the work depends, as well as the selection of materials.
In order for this event to be effective, you need to learn that there are only two types of noise sources. This is the penetration of sound waves due to thin partitions between the walls and the ceiling. In this case, everythingwork is reduced to cladding with appropriate materials. Or it is a noise of a vibrational nature - it is he who creates a serious problem during insulation work. In this case, the noise source may be remote. Vibrations can pass through all contacting planes through facing materials. Therefore, in order to reduce these fluctuations, it is necessary to use special, dedicated and effective materials.
It should also be taken into account that sound can enter a room not only through ceilings or walls. Sound also effectively penetrates through windows, various communication wells, cracks or crevices. If this is the case, soundproofing a room may not be effective if all these factors are not taken into account.
Which materials to choose
Remember that these materials vary greatly in their purpose and also in their effectiveness. Before purchasing them, it is recommended that you study their features as carefully as possible.
Many people confuse heat-insulating materials with noise-insulating ones. However, some of those products that are designed for insulation, quite effectively absorb sound waves. Perhaps, in some cases, simple thermal insulation will be enough to create silence.
All materials designed to eliminate noise can be divided into absorbing and reflective. To achieve maximum effectiveness, they must be used in combination.
Features of materials
Materials for soundproofing differ in one feature - thisdirection. So, their structure consists of several layers. Before soundproofing a room, it is recommended to take into account the direction of sound absorption. And to increase efficiency, it is best to lay the material in two layers with opposite sides.
There are also elements for vibration isolation. They have absorbent properties. Install it even under various mounting structures. Often, foamed silicone or other rubber-based products are used for this. Efficiency here depends on the thickness.
Do-it-yourself room soundproofing
To make the room really quiet, you can use drywall technology. At the same time, soundproof products can be placed in the cavity between the drywall and the walls.
Many believe that there are serious differences between ceiling and wall work.
It's not. Technology is one. But to perform work on the floor, it is recommended to use sound insulators of greater density. Then, after laying, they should be covered with any floor covering.
Wall work
First of all, you should inspect the walls for cracks, various strobes or internal sockets. If you find something, it is desirable to eliminate this problem, otherwise the efficiency of getting rid of noise will be close to zero. Gypsum plaster is best suited for these purposes.
Now you need to build a frame. You can use drywall. You need a profilefor him. You can also use wooden slats. In addition, you should prepare fasteners that are suitable for attaching the sound insulator to the wall, the material itself, drywall sheets and self-tapping screws.
Stages of work
First of all, the frame is created. But there is a small nuance here. Do not fasten the profile directly to the wall. Professionals recommend retreating from the wall by about 2 cm. Materials must be placed under the metal profile to absorb vibrations based on cork or rubber. It should be laid with maximum density. Then, after you get the frame, you can proceed to the next step - laying the funds. If you need effective soundproofing of a room, the materials for this purpose are mineral wool, glass wool or non-rigid slabs.
When choosing the right insulator, carefully read the sound absorption coefficient. If the material is soft enough, then this value will be higher. This means that absorption and noise isolation will be much more effective.
Now you can install drywall sheets on the profile using self-tapping screws. Well, then you can do the finishing.
Price
Soundproofing the walls in the room will not cost too much. So, drywall has an average price of 90 rubles. Sound absorbers will cost from 60 to 400 rubles. Well, add here the cost of self-tapping screws and a profile.
Ready-made decorative panels for noise insulation
Today the market offers several of these panels. So, if the wall is not too smooth, thenyou may need to perform trimming. Then the panels will be fixed to the grid with liquid nails. They are connected to each other by the tongue-and-groove method. This is a fairly effective and beautiful soundproofing of the room. In addition, the installation of such panels is very simple. Often these products already have a decorative finish based on fabrics or paper.
How much does it cost
Prices for these products average about 750 rubles. for 1 m2. Their efficiency and properties are quite comparable with the same mineral wool. Among the advantages - extraordinary lightness. For example, one panel has a weight of 4 kg.
This is suitable for those who want to complete the entire room. Also, the panels can be a great decoration for the interior.
Stick material on the wall - simple and inexpensive
This is the cheapest and easiest way. It does not even need mineral wool. In this case, sound insulation in rolls is simply purchased. It is conveniently glued to the walls with glue for vinyl wallpaper. Such a substrate will cost about 1310 rubles. for 1 roll. This is 7 m2. But this is a budget and not very effective solution. The noise level in this case will decrease by only 60%.
This is true for those who rent housing and do not want to make expensive repairs.
Material for soundproofing the walls of the room: which is better?
Acoustic experts claim that soundproofing materials do not exist. There are only designs for this. But we'll look at some sound deadeners anyway.
Zips systems
These are sandwich panels, as well as special facing sheets based on drywall. This panel is a dense and soft materials. So, gypsum fiber is used as a dense layer, and mineral wool or glass wool is used as a soft layer. As for the thickness, it depends on the specific model. There are special structural units for fastening panels to walls.
ISOTEX
This material is based on environmentally friendly softwood fibers. These durable, maximum resilient and flexible panels will save you from airborne noise and vibration. Such products are decorated with vinyl wallpaper or a special linen fabric. They are easy to install as well as clean.
For an ordinary apartment, special acoustic panels are considered the best material, but if it is expensive, then mineral wool will do. This solution is inexpensive and of high quality.
Now you know how to soundproof a room. You don't need any special skills to do this. Any person can handle this, and in return they will receive complete silence.
