Learning to determine the sources and nature of noise
Before sound insulation of the floor, walls and ceilings of the apartment is carried out, it is necessary to correctly determine the source of sounds. That is sometimes easier and more economical to control or eliminate directly the source itself. Sometimes the elevator can rumble or neighbors rustle. Often it happens that just your house is located next to the road, and you can hear the sounds of vehicles.
In order to determine the nature of noise, it is important to conduct a series of studies. How to do it, we will tell below. First, we identify where the sounds come from. If it's barking dogs, screaming neighbors, then you have to deal with air noise. In the event that anxiety is caused by steps or trampling, it is a shock noise. Well, or maybe it's the sound of an elevator and other equipment. This is structural noise.
Next, the frequencies are determined. They are already selecting a soundproof material( each has an acceptable acoustic load on the packaging).
Secondly, it is necessary to examine the premises in detail. It is important to pay attention to whether there are cracks and cracks. Typically, cracks and crevices for panel houses are characteristic. It is also important to pay attention to sockets, switches. In some cases it is necessary to make switches and sockets external, instead of internal. All existing cracks and cracks should be repaired before the insulating material is laid.
Noise isolation of the apartment floor: typical errors
Before asking how the sound insulation of the floor is made by one's own hands, let's take a look at the typical mistakes that occur in the process. If you avoid them, you can assume that half of the work has already been done. So, to begin with it is worth listening only to professionals or professionals. Do not accept the recommendations of experienced "advisors" who do not really know what's what.
For example, if you are told that the best material for floor noise insulation is polystyrene, then know that an acoustics specialist would never advise this. The fact is that this material is not soundproofed, since its noise absorption coefficient is extremely low. Most often it is used in the general structure of floating floors.
Also do not place high hopes on paints, carpeting. They are usually used as an additional means, but by no means the main one. At best, they will get rid of the echo in the room.
How to make floor noise insulation?
In the event that a soundproofing is planned for a laminate, linoleum or any other coating, the technology is extremely simple. First, remove the old floor. The base is cleaned of dust and dirt and checked for gaps and cracks. If there are any, then it is important to seal them. At the same time, mineral wool is used. Accurately clog her all the holes. After this, installation of wooden logs begins, on which it is first necessary to put polyethylene.
The lag laying itself should be carried out in such a way that the soundproofing material can be placed in the lumens( cages).For a more even installation of the log, self-tapping screws and level are used. Then in the gaps are placed materials for floor noise insulation( any of the listed: mineral or stone wool, gipsovolokno).
Next, the surface is poured with a concrete screed and laid some kind of covering. This can be both plywood and fiberboard. Well, a massive board, a parquet, a laminate, etc. are placed on the formed structure. On this one can assume that the floor soundproofing is done. Note! When installing the log, be sure to make a 20 mm clearance between the wall and the entire structure. It must also be filled with soundproofing material.
