Soundproofing floor - how to avoid common mistakes ?

Learn to identify the sources and nature of noise

Before the floor will be insulation, walls and ceiling of the apartment, it is necessary to determine the true source of the sounds.That is sometimes easier and more economical to control or eliminate the source itself directly.Sometimes it can rattle the elevator or noisy neighbors.as often it happens, that your house is located just next to the road, and heard the sound of vehicles.

In order to determine the nature of the noise, it is important to conduct some research.How to do it, we describe below.First, identify where sounds come from.If the barking dogs, screaming neighbors, it will have to deal with the air noise.In that case, when anxiety steps or deliver the tramp, this impact noise.Well, or maybe it's the sound of the elevator, and other equipment.This pattern noise.

further define frequency.As it is already selected sound-insulating material (written on the packaging of each speaker permissible load).

Secondly, it is necessary to inspect the room thoroughly.It is important to note whether there are cracks and crevices.Usually characterized by cracks and crevices for prefabricated houses.It is also important to pay attention to sockets, switches.In some cases it is necessary to make external switches and sockets, rather than internal.All existing cracks and crevices is repaired before the insulation material to be laid.

Noise floor apartment: typical mistakes

Before wondering how to make a soundproof floor with their hands, let's look at the typical errors that occur in the process.If you avoid them, you can assume that half the work is already done.So, to get started is to listen only to experts or professionals.Do not take the recommendations of experienced "counselors" who do not really know what's what.

For example, if you say that the best materials for sound insulation of a floor - foam, then know that the acoustics expert would never advise this.The fact that this material is not applicable to sound-proof because its sound absorption coefficient is very low.Most often, it is used as part of the general construction of floating floors.

Also, do not have high hopes for paints, carpets.They are typically used as an additional tool, but in any case, not the main one.At best, they get rid of the echo in the room.

How to make sound insulation sex?

In the event that planned sound insulation under laminate, linoleum or any other cover, the technology is very simple.To begin with remove the old floor.The base was purified from dust and dirt and examined for cracks and fissures.If there are any, they are important to patch up.Moreover, when using this mineral wool.Gently hammer in her all holes.After this, the installation of wooden log, which you need to put a pre-polyethylene.

itself laying the lag should be carried out in such a way that the gaps (cells) could fit sound-insulating material.For a smoother installation lag screws and the level of use.Then put in the gaps soundproofing materials for the floor (you can use any of the following: mineral or rock wool, gipsovolokno).

Then the surface is poured a concrete screed and put some cover.This may be as plywood and fiberboard.Well, on the resulting structure is put solid wood, parquet, laminates, and others. In this we can assume that the floor sound insulation made. Note! When the device lag necessarily make 20 mm gap between the wall and the whole structure.He subsequently also need to fill in the material for insulation.
