how to fight, what distance- Review + Video

Building your own home and arranging the local area is a rather important step. Not the last thing in it is the choice of a site suitable for construction. We are surrounded by a civilized, comfortable world, which not only provides us with all kinds of conveniences: in addition to them, we get noise and polluted air.

Numerous transport, railways and airports and, accordingly, trains and airplanes cause incessant noise and rumble. Constant background noise, in turn, causes poor health.

Often he is guilty of poor health, irritability, insomnia, increased blood pressure, and so on.

A little theory about road noise

It's great when your home is in a quiet, secluded place. But there are not so many lucky ones enjoying the silence. The overwhelming majority have to somehow adapt, and, to the best of their strength and capabilities, fight annoying decibels. To isolate yourself from noise, two different techniques are used:

• sound reflection,
• sound absorption.

Well-thought-out combination is most effective. For owners of private houses and their own plots, it is, of course, easier to deal with noise. Especially if the size of the territory allows it. The larger the plot, the more optimally you can plan the structure and location of the house, and competently improve the garden plot.

Protecting ourselves from the noise outside

We conquer the noise if the house is by the road

True, it should be:

• made of fairly dense material,
• not have cracks and openings,
• have a height of three meters.

The choice of homeowners most often falls on fences made of brick, concrete blocks or corrugated board. This, of course, is a good protection of the house from uninvited guests and prying eyes. But their noise-absorbing characteristics are the most insignificant.

They are much higher, for example, near a solid wooden fence, which will perfectly fit into any landscape. But wood, especially when not properly processed, deforms and decays over time.

Cracks and flaws can form on it, which will allow street noise to pass through.

Green spaces will help to perfectly fight noise. A higher degree of protection is possessed by rather large trees - from five meters high. They should be planted in two to three rows in a checkerboard pattern. Pine, then spruce, and then various types of deciduous trees are best resisted to noise.

Special acoustic screens that widely distributed in Europe, a very effective and fairly low-cost tool. They are installed along the perimeter of the estate or plot not far from noisy roads. The fact is that their efficiency increases as they get closer to the source of the noise.In each case, the necessary parameters are calculated individually, and this is carried out by qualified employees of the acoustic laboratory.

Screens can be made of:

• concrete,
• polycarbonate
• aluminum.

It is desirable that acoustic screens and green spaces completely protect the house from the noisy side.

Choosing a layout for noise isolation

During the day we do not notice extraneous noise as much as at night. Based on this, it is advisable to plan the layout of the rooms so that the bedroom windows face the quiet side.

On the side of noisy roads and highways, storerooms, laundries, stairs or kitchens should be located.

In the noise absorption room use:

• volumetric curtains with drapery,
• carpets and upholstered furniture,
• it is better to equip fewer window openings on the side of noisy avenues,
• the windows themselves should have excellent sound insulation ...

Many believe that with increasing properties.

But this is not quite the case.

It may well be a single chamber package. If you choose one with a low-emission coating, then its thermal characteristics will also be at their best. When buying, pay attention to seals and locking mechanisms: it is their quality that guarantees tightness.

Protecting ourselves from the noise from the inside - choosing special materials for the walls

The wall of the house is a powerful barrier to noise. Therefore, the material from which it is made is of great importance. The highest soundproofing properties are possessed by buildings made of monolithic reinforced concrete. The minimum number of seams provides just such indicators.
If it is decided to build a building of bricks, then the difference in the functional characteristics of different grades must be taken into account:

• silicate and porous bricks have the best soundproofing properties,
• grades of their hollow and ceramic analogs are less effective in this regard,
• porous shell rock is able to significantly reduce noise indicators ,
• the multilayer structure is more important than the material that makes it up - this is an important fact.

But this does not mean that a two-layer brick wall has two times better properties than a single layer. To provide better sound insulation, it is desirable to combine different materials. For example, lay a layer of basalt fiber or glass wool on a brick wall, upholster it with sheets of drywall or combine the wall with layers of shell rock and brick.Natural or bituminous shingles also successfully resist various road noise.

Frame-type residential building: types of possible noise and their reduction

When choosing the type of potential home, many potential homeowners are sure in advance that it is impossible to provide good sound insulation for a frame structure.

Is this so?

Modern technologies offer different ways to solve this problem :

• special materials made with the latest technology,
• special design dwellings (arrangement of noise-absorbing partitions and floors).

Conventionally, all annoying noises can be divided into two groups: shock and air type. Trying to get rid of each of them using special methods, you can achieve good sound insulation of the frame structure.

Reducing airborne noise

This type of noise is the most common and widespread.

Airborne noise is everything that spreads by air:

• dog barking,
• noise and din from the playground,
• the sound of strong wind and rain outside the house,
• the sounds of a running vehicle engine.

Due to the vibrations of walls and vertical partitions, through cracks and gaps, they spread along the structure itself, inside it. Wooden walls have rather high characteristics of protection from such noise: their effect extends to frame houses.

However, additional measures will not be superfluous:

• absolute adherence to the rules for assembling a house,
• full adherence to the technology of assembling a house,
• high-quality door and window structures,
• the use of additional finishing materials in order to reduce the sound transmission of walls.

Ideally, they should, without increasing the weight of the building structure itself, reduce possible vibrations of the floors.

As such, it is good to use:

• a laminated material in which a porous fiber material is combined with a dense,
• special gaskets made of foamed polyethylene or cork, they will significantly improve the soundproofing qualities of floors. The thickness of such a protective layer should be five to six millimeters.

Foam and polyurethane, contrary to popular belief, are not a guarantee of excellent sound insulation. Their closed cellular structure does not contribute to damping sound waves.

Reducing impact noise

Impact sound travels very quickly in a solid environment and over long distances.

In rooms, this sound propagates through floors and floors.

Impact noise can occur, for example, when:

• a spoon hitting tiles,
• when drilling walls,
• hammering in nails,
• moving furniture,
• walking around the room, and many other reasons.

True, this method is not suitable for a light frame structure. In frame-type buildings, you can use a variety of floor coverings, soft and flaky.

It can be carpet or linoleum on a thick foam base.

3mm cork or polyethylene spacers during installation floors are used in rooms where the following will be used as a topcoat:

• laminate,
• hard linoleum,
• parquet.

These materials are placed between the leveling screed (or monolithic coating) and the supporting structure.

Glass fiber or basalt fiber 3 centimeters thick to provide reduction noise is placed under the ceramics. The fiber acts as a kind of floating floor, which in permanent buildings will serve to dampen impact noise.

From all that has been said, it follows that there are different ways that are aimed at improving the sound insulation of frame-type buildings. Of course, many of these increase the overall construction costs. However, all investments of this kind are vital and well-founded.
