How to protect yourself from unnecessary noise
Neighbours top to me, the bottom neighbours without interruption Voet dogs, neighbors left forever rebuild their apartment and haunt you man drills, and the window is busy road, the roar of engines and wailing alarm. Say, the picture is not very encouraging ... And given that intense sound dangerous for the health and can cause increased aggression and even stress-start thinking about how to protect themselves from unnecessary noise.
First of all, you must understand that between acoustic insulation and sound absorption is a significant difference. The first term refers to reflect sound waves, and the second of its acquisitions. The limited space only finish absorbent material is not. Marine Construction work better.
For example, to reduce noise at 50 dB, an absorbent material layer thickness of two metres. A layer of the same fire material, in this case, should be the thickness of 10-20 cm, ideally, the sound space is so that the material and reflect, and absorbed sound.
If possible, preferably in advance to think about audio comfort of your home. In fact, the sound is primarily determined by the weight of internal partitions, ceiling, floor and walls, and then the products.
The thicker wall, the more it will reflect sound. Besides bricks, other building materials are well reflected sound. Among them - place reinforced concrete, and keramzito- penobetonnye blocks. The main thing is that they, together with the connecting water-sealed structures formed without gaps and holes. So it is only through the mass ceiling and walls with appropriate tightness compounds can be good noise.
But there are also subtleties. Even if you pick up the bulk of construction doubled soundproofing grow by only 6 dB, which is not too many. But with the increase in mass and thickness of the wall will rise. This in turn will increase the pressure on the foundation that in the case of multilevel buildings might end up miserable.
They significantly reduce noise and light enough for construction standards. To combat the decibels need to use at least two layers : a hard (plasterboard, gipsovolokno or brick) and soft (zvukopoglotitel). Part of the sound waves reflect the first layer of the second-absorbed.
For good sound absorption material to be porous, EExp, it is able to skip through the air itself, and of course quite tight.
Often zvukopoglotiteli are part of the interior. Hence, they should have prezentabelnuyu appearance, but also water and fire. Last not least because many goryuchi absorbent material and can release toxic substances during combustion.
Experts say that the cause of 70% of tenants to noise complaints, the sound is transmitted through the floor. It almost does not matter what the house is built, sound will vulnerability in soundproofing as a brick, and solid buildings, not to mention the block or panel.
Bad if you flat on the floor pushed ceramic tiles. In addition, excess noise can be low massiveness bands, rigid in its structure, as well as the stiffness of the material field.
One possible way out is to apply the so-called "floating" floor, when the finishing floors (parquet, linoleum, tile), or by smoothing plate fit thin zvukoizolyatora.
Springs construction of stekloholsta thickness of 3 mm, carried by levelling plate thickness of 60 mm, reduce the impact of noise levels at 23 dB, and steklomatov layer thickness of 20 mm by 37 dB. Moreover, the field dimensions are podlozhit sheets penopropilena, cork agglomerates, kremnozemnoe fiber or any other elastic cushioning.
Paul called "floating" because parquet board or plate must not come into contact with the side wall. Violating this condition, you will significantly reduce fire effects. But then between the floor and the floors are formed units, which will be transmitted sound.
