The advantages of the house of the tree in front of stone buildings attracts more and more wishing to such buildings. Environmentally friendly, warm and cozy house, which remains heat for a long time, is an indicator of a refined taste and a certain wealth of its host. In addition, the wooden house is not electrified, and dust is almost not going to. However, a sound insulation is always needed for a comfortable stay.

What is the sound insulation?

Along with a lot of advantages, the tree is an excellent sound conductor, and the structure of it has many resonant frequencies, on which the sound is enhanced several times. This property of wood products are used when creating musical instruments, manufacturing special resonance panels for concert halls.

However, in the built wooden house a huge amount of sound resonance, and those that are simply transmitted through the walls without amplification, they will deliver a lot of trouble to the owners who wish to relax in silence. That is why therefore the construction of wooden houses necessarily take into account the need for sound insulation with the use of modern materials.

It should be borne in mind that on the principle of implementation, two main types of sound insulation are distinguished:

• soundproofing is a series of measures to reduce the penetration of sounds outside in the residential premises;
• sound absorption - carrying out measures to reduce the passage of sounds from the room outward.

Planning noise insulating activities, the valid noise level requirements should be taken into account.In particular, for residential premises, a maximum daytime level of 40 dB is installed, and during the day 30 dB. You can measure this level using special devices - noiseomers. Increasing sound levels (noise) above these limits significantly reduces the comfort of stay in the room, and the level of 120 dB is already dangerous for hearing organs.

By specifying the factors affecting the level of noise in the room, it is necessary to consider that:

• the whisper creates the sound level of 20 dB;
• quiet speech - 40 dB;
• noise from the passing car - about 80 dB;
• music player - an average of about 90-100 dB;
• fireworks and Petardes - up to 130 dB.

Varieties nois

Before planning noise insulation measures should take into account the main sources of noise and the types of noise from which it is necessary to protect the indoor facilities of a wooden house. External noise can be divided into several types.

Acoustic

These are sounds propagating the air and are acoustic waves. Sources of such noise can be both conversations of neighbors and working audio equipment (players, tape recorders, amplifiers, radio tape recorders, TV), sounds from engine engines, animal voices.

Drums

This type of sounds are transmitted quite well and far directly by solid bodies to which the shock or vibrational impact is applied. Such sources include, for example, perforators, hammer blows, the tramp of walking people, the sound from the objects falling to the floor, the sound of the railway line.

Combined noise

This is the presence of noise of both acoustic and drums. For example, the same perforator creates two types of noise. When exposed to the nozzle on the surface, frequent strikes are created, and from the operation of the perforator engine - acoustic noise.

Thus, when conducting noise insulation, it is necessary to take into account which sources of noise are near, and from which type of noise it is necessary to isolate the room. In addition, the audio intensity should be taken into account (its volume).

Types of noise insulation and its installation

First of all, for effective noise insulation, it is necessary to eliminate sound bridges in the room, which occur in places of connecting wooden parts and beams. Through these bridges, sounds are very effectively transmitted, in addition, there are additional resonant frequencies in these places where the sound is enhanced.

When conducting sound insulation of premises, various materials and compositions are used, such as firmware mats, ready-made plates from different material, rolled sound insulation, liquid compositions applied by spraying.

The use of one or another material depends on the type of wall design, floor and ceilings of the room. Thus, when framework, it is necessary to fill in the inner part of the wall with special sound insulation materials, and in this case the wall consists of three parts (two outer coated and internal sound insulation).

• In the case of limited thickness between the outer parts of the wall as a sound and heat insulator, use polyethylene foamed or polyurethane.

• To reduce sound transmission between wooden parts of the house use Sound insulators from glass gamblersand other materials. They are located between the beams and lags, eliminating the immediate contact of the wooden parts of the structure. And also to reduce the level of sound transmission and vibration, beams are wrapped with special construction felt, and under the floor placed a polypropylene or cork substrate. Such work is made in the construction of the house, as it is later difficult to fulfill them.

• Very simple but very effective is flooring in places of stop on sound insulators without rigid fastening to the base.Thus, it turns out the "floating floor", not connected to the rest of the design. This ensures very high-quality sound insulation. And also uses the option of fastening floors on damping support springs or brackets, which requires the use of special springs (brackets) designed for greater load. At the same time, the load is calculated on the basis of the total weight of the floor with furniture plus the weight of several people (depending on the area of \u200b\u200bthe room).

• For additional inter-storey noise and thermal insulation Between the ceiling and the floor of the next floor, it is most often covered with a clay crumb. It is light, but at the same time perfectly performs its functions. Sometimes they fall asleep and sand, but at the same time it is necessary to significantly increase the overall strength of the design, given that the total weight of the structure will increase, use stronger materials for the ceiling. In order to reduce the total weight in the sand add leaves or dry sawdust.

You can start soundproofing and do it yourself, gradually applying certain methods.

In particular, it should be started with careful embelling of all the cracks through which sound passes, special mastic or putty. Voids made to install electrical switches are filled with mounting foam. Seal the inputs of water supply and gas pipes into the house with the help of elastic sealants.

In the implementation of intercommunicable sound insulation, noise-insulating materials are located in the voids of wall partitions. Often, sound insulation is combined with thermal insulation by applying heat-insulating materials lined with plasterboard.

In general, noise insulation of walls in a wooden house requires a comprehensive approach with eliminating all possible sound conductors indoors. At the same time, the location of the ducts, which, especially made of wood, are excellent conductors of sounds both indoors between rooms from neighbors and outside - to the room.

Cork soundproofknown for a long time, it was used in the construction of various houses and buildings. For example, on the Black Sea coast in Gagra (the former name of Gagra), a small castle was built specifically for recreation of members of the royal family, in which in all walls and doors in order to increase the efficiency of sound insulation are laid stoves from traffic jams. Thus, the sounds outside almost do not penetrate the rooms of this building.

Currently also applies panels made of cork trees to finish the premises. Such panels, except for an excellent appearance, successfully perform the function of sound insulation. Sound insulation membranes made of cork wood apply not only when finishing houses, but also during the construction of professional recording studios, where the high-quality sound insulation of the room where the sound is recorded is essential for obtaining high-quality sound.

And the sound insulation of the wooden structure can be performed using modern special liquid adhesive compositions. In this case, the quality of sound insulation is at a fairly high level.

Very often, foam, polyurethane and other materials are used to perform sound insulation, which are quite successful absorbing the sound wave, are not subject to corrosion and are very durable.

The correct soundproofing of the walls is a pledge of a comfortable pastime.

The partition is used to separate space on zones in private buildings, offices or public spaces. Soundproofing interior partitions is an important factor. Waves of sound can pass through the surface. To stop them, you need to reduce sound pressure. This uses various sound insulation materials. This article will consider how the partitions sound insulation and that it is necessary for this.

Distribution and absorption of sound

Sound is called mechanical oscillations that apply to the source in an elastic medium. Creating oscillations, the source forms a pressure that is distributed in different directions. A sound wave formed as a result of such processes penetrates human hearing organs and transmits fluctuations on the eardrum, which is perceived by the brain as a sound when vibrating.

Sound propagation characteristics are directly dependent on the density of the medium and can vary greatly. For example, if the sound on its path meets any obstacle, its waves are reflected or refracted.

If there is a porous material on its path, it absorbs the wave by inner dispersion. This characteristic of products is often used in construction for or other surfaces. The materials produced taking into account such features are the name of sound absorbing or sound insulation. In the following table, you can see a comparison of such materials.

Soundproofing of plasterboard structures

Products from plasterboard sheets are becoming increasingly popular. When solving, split the space of the room into zones of noise insulation should be ensured necessarily. With proper planning, costs will be small. The following video will help you familiarize yourself with such a procedure.

Itself has a high level of soundproof, but it can be enhanced with the following actions:

• application of materials with sound insulation;
• noise insulation of walls by special technology;
• the use of fasteners with sound insulation when mounting a frame;
• application of special profiles;
• an increase in the interval between partitions;
• use of frames with a large thickness;
• an increase in the thickness of the finish;
• the use of various frame fillers.

The plasterboard partition is placed in two layers: the external is a shell of a material sheet, and the internal assumes the installation of a special filler.

Its cost is quite high, so you can use fillers. Porous plates in the soundproofing partitions are the main component providing noise insulation.

Soundproofing the partition is impossible without taking into account the metal frame, which is a good sound conductor.

Under the initial horizontal profiles, you will need to put the sealing tape, and metal mounts are mounted with polymer gaskets.

Soundproofing frame partitions is as follows:

• One side of the frame is trimmed with a leaf of plasterboard.
• Communication laying, installation and connection of sockets and switches is performed.
• In the inner part of the partition is hampering sound-absorbing material. Between the sheets should not be empty sections.
• The layer is covered with a membrane or porous ribbon.
• On the other hand, a plasterboard sheet is mounted.
• The slots and empty spaces are filled with sealant.

Comparison of various partitions with noise insulation can be seen in the following table.

Using new developments

Greater competition in the building materials market causes manufacturers to invent new soundproof materials. Work is carried out in the following directions:

• production of acoustic drywall;
• the use of special fillers with noise absorption functions for partitions;
• plastic gaskets that are mounted under the frame and have a function of reducing sound from impact;
• filling partitions and installation of fake walls;
• spraying fibers inside structures.

Acoustic plasterboard

Various brands began producing such a drywall, which significantly reduces the noise level when finishing interior partitions or the processing of other surfaces. Good sound absorption is ensured by a large number of holes that reflect sound waves directed to the coating. In addition, on the reverse side, a nonwoven canvas with sound absorption feature is pasted.

Noise absorbing filler

Soundproofing partitions is possible at the flooring inside the sound absorbing filler. For such purposes, polystyrene foam is often used. In addition to sound insulation, the finish can provide a good level of thermal insulation. When adding antipyrin, the fire resistance of the filler significantly increases.

Mineral wool plates also have good sound absorption. For sound insulation, acoustic stoves are commonly used with a thickness of no more than 4 cm. Good sound insulation can provide only homogeneous plates.

Fillers for partitions with improved sound insulation parameters have a higher cost, but allow you to achieve complete noise insulation in the home. In addition, you can use a filler of a lesser thickness, which reduces the cost of work and loss of space space.

High quality sound absorption is able to provide membranes from a thin pile coating membrane. Their thickness can vary from 2.5 to 12 mm.

Panels made of polyester and polyurethane foam are used as internal fillers and when installing fake walls. Some varieties may be fire hazardous, as they contain flammable materials.

Inexpensive filler is. It slightly reduces the noise level, but has extremely low efficiency.

Spraying coatings

Spraying products are often used by the low cost of simplicity of procedures. This method allows you to adjust the acoustic parameters within the entertainment and public buildings. It will take help from experts.

The possibility of spraying the foamed composition of cellulose on various surfaces allows you to abandon the installation of the framework, which is used to hold drywall partitions. The method is inexpensive and no high difficulty.

When using special tools, the soundproofing of partitions can be increased by applying cellulose from the inside.

Errors when creating sound insulation

Beginner builders often allow mistakes when trying to sound interior structures. The most common miscalculations are:

• Facing houses only sound-absorbing components. In order to increase sound insulation, the material must be used together with special panels, as well as apply large fencing with acoustic junction in the adjoint areas.
• Placing noisy equipment in rooms with partitions. The effectiveness of the noise-forming materials has borders. It will not always be possible to create high-quality protection from sounds. Equipment emitting a large number of sounds, it is better to have a distance from partitions.
• Soundproofing partition with three layers of plasterboard with filler. For high efficiency, you need to use special components and mount gaskets between the frame and the partition, as well as fill the joints with special sealants.
• Soundproofing buildings with thin soundproofing screens. The sound insulation partition can be created only with structures with a minimum thickness of 40 mm.

Sound-insulating screens can be seen in the following photo.

As can be seen from the article, the soundproofing of partitions is possible in different ways. It will only be necessary to carefully choose the material, since it is from it that the level of protection against sound will depend on it. Work is not too complicated, so even a newcomer in the construction craft will be able to cope with them. Thanks to the photo and video used in the article, it will be possible to see how this procedure is performed.

Protection of residential premises from extraneous sounds - this is the task of the implementation of which the builders break the head from the moment of the construction of the first buildings. One of the most effective methods to protect the rooms from unnecessary noise was the installation of plasterboard partitions with sound insulation.

Distribution of sound and its absorption

The concept of "sound", as its physicists determine - these are mechanical oscillations distributed by any source in an elastic medium - air, wood, metal, etc. Publishing fluctuations, the source creates pressure (low or elevated), which extends all directions. The sound wave formed at the same time entering the human hearing organs and transfers fluctuations on the eardrum, the vibration of which is perceived by the brain as a sound.

Sound propagation parameters are largely dependent on the density of the medium and can change significantly. So, encouraging the obstacle, sound waves are reflected or refracted. If there is a porous substance on their path, it absorbs the wave, dissipating it within himself. This physical property of materials is widely used in construction, for example, with noise insulation of ceilings and plasterboard partitions.

The greatest scattering of sound energy is due to an increase in the amount of pores and voids present in the substance. The materials themselves made taking into account these features are called sound-absorbing or sound insulation.

Types of soundproofing materials

So, having studied a brief theoretical certificate, we can conclude: Effective protection of the dwellings from foreign sounds is impossible without using additional materials. The modern market offers a huge amount of solutions to achieve the required level of sound insulation of the premises. Materials that are used in the fight against excessive household noise are divided into two main categories:

• Sound absorbing (Figure 1). Able to absorb sound waves, preventing them from reflecting and further spread. They have grain, fibrous or porous structure and are most suitable for protecting residential premises from outsiders, thanks to light installation, optimal characteristics and low cost. For example, they are widely used during sound insulation of overlaps and partitions from plasterboard.
• Soundproofing (Figure 2). Prevent the penetration of sound oscillations, reflecting them. Noise insulators are distinguished by massiveness, since it is the thickness and mass that affects their sound permeability. The most common, reliable and high-quality materials, insulating the sound, are concrete, brick and plasterboard.

Note that only the joint, combined use of these materials allows to achieve the necessary effect in the housing equipment with sound insulation.

Materials for noise insulation of partitions

The choice of soundproofer largely depends on the nature of noise. To combat "air" noise (loud cry, music or a neighbor dog) use materials with a porous structure (soft or semi-rigid). "Impact" noise (sound from falling items, trap steps or vibration drill drill) effectively eliminate only dense gasket (hard) materials.

Among the most common and most effective materials used in noise insulation of plasterboard partitions should be noted:

• Glass gambler. Elastic, non-combustible, durable and vibration resistant material. It is easily ease and elasticity. The glass gamble does not absorb moisture and has a high sound absorption coefficient. It is made in the form of rolls or briquettes and conveniently mounted.
• Mineral wool. Material made of silicate and metallurgical slag material is distinguished by the unique characteristics of sound insulation. The advantages of mineral wool are absolute non-combustible, environmental purity and the possibility of creating, with its help, multilayer structures. Noise insulation of the plasterboard partition, using this material, will not be much difficult, as it is very easy in installation and relatively inexpensive.
• Pressed cork crumb. These sheets have excellent insulating characteristics, are not subjected to rotting, influence of insects or rodents. The plug is distinguished by durability and environmental friendliness, but its use, compared to the rest of the soundproofers, is common less frequently due to quite high cost.

Soundproofing of interior particles from drywall

Building a new home or changing the standard planning of ready-made housing, we often think about installing interior framework partitions for more efficient zoning and increasing the useful area of \u200b\u200bpremises.

We will not describe all stages of the construction of structures, since this will be devoted to a separate detailed article. We will tell only about the peculiarities and benefits of partitions, as well as the rules of their sound insulation:

• Since these designs are not carriers, use heavy massive brick or concrete, with their manufacture, optionally.
• In a wide range of building materials intended for such work, the greatest preference is given to the plasterboard. His advantages are that it is universal, inexpensive, easy to install and is distinguished by an ideally smooth surface.

However, along with the installation, one should not forget about sound insulation of plasterboard partitions between rooms.

• The design efficiency depends on the combination of a soft inner layer absorbing noise, with rigid sound-pressing outer layers.
• The soundproofing level in such structures depends on the thickness and stiffness of the facing layers, the width of the gap between them, as well as the coefficient of noise absorption of the inner material.
• Narrow multi-layered partitions are much more efficient than thick monolithic. In addition, they can significantly save the useful housing area.

Having equipped a soundproofing septum with soundproofing, it is necessary to remember that the places of fastening the frame to rigid structures, the ceiling and the floor, it is necessary to isolate with elastic gaskets.

Important! For security reasons, the entire wiring mounted in the interior partition must be laid only in corrugated tubes!

Modern ideas about the ergonomics of the working and residential space, current interior design trends suggest the highest possible layout of the premises, a good level of illumination, ventilation and sound insulation.

The problem of reducing the level of noise in buildings has gained special relevance in recent years. In large megalopolis, a huge number of noise sources: transport, mechanisms, technician create a uncomfortable environment and interfere with normal work and rest people. Traditional walls and partitions installed in the premises do not meet modern requirements for comfort: they take a lot of useful area, have high sound permeability, worsen illumination, impede ventilation.

We often face the need to divide a large room into smaller. At the same time, it is hardly paramount to newly formed rooms has acoustic polls. The separation occurs by erecting new capital or time wall structures - partitions. It is about them, or rather about how to enhance sound insulation of interroom partitions and will be discussed.

From a constructive point of view, interior partitions can be divided into two classes: single-layer and multi-layered.

Single-layer structures involve the use of any self-supporting relatively dense building material on a rigid binder (solution). These may be brick, plaster, ceramzite concrete and even reinforced concrete structures. Their sound insulation characteristics are determined, first of all, weighing and are improved by about 6 dB when it is doubled.

The porosity of the partition material also plays a role in ensuring its sound insulation qualities. However, as practice shows, the winnings due to the increase in the porosity of the material is leveled by losses due to the weight of the construction. Therefore, with rare exceptions, such partitions have sufficiently modest sound insulation.

Multilayer partitions, as follows from the name, consist of several (minimum three) alternating layers of hard (dense) and soft (lung) building materials. Dense materials (drywall, brick, metal) show sound insulation properties and work similarly to single-layer partitions: sound insulation is the higher, the greater the surface density of the material. Materials of the lung layer perform a sound-absorbing function, i.e. The structure of the material should be such that during passing through it sound oscillations the latter weakened by friction of air in the pores of the material.

It should be noted a low efficiency of use in sound insulation partitions of materials such as foam, polyurethane foam or cork. This is due to the fact that for good sound insulation materials, they have an insufficient density, and to calculate them to the class of sound-absorbing materials - too low absorption due to the lack of air purge.

The most common variant of the multi-layer partition is a three-layer frame-and-in-wing plasterboard partition. Its soundproofing characteristics depend on a larger number of factors than the single-layer partition. Ways to achieve the necessary sound insulation of the plasterboard partition only three:

• Increase the density of material of hard layers
• An increase in the distance between the extreme layers, i.e. An increase in the total thickness of the partition.
• Filling into the internal space of the septum with layers of a special sound absorber.

The most important thing is to implement the entire soundproofing potential of multilayer structures, the requirement of layer-by-layer sound through the thickness of the partition should be performed. Ideally, the sound wave must pass first only through the first rigid layer, then only through soft, then only through the second rigid layer, etc. In practice, the mandatory presence of a carrier frame leads to the fact that the sound oscillations of the first rigid layer are transmitted through a common frame (or common foundation) to the last rigid layer and re-energized them into the protected room. Thus, sound energy for rigid frame elements successfully passes specially prepared internal sound-absorbing layers traps, as a result of which the real soundproofing of multilayer structures is significantly lower than theoretically calculated values.

Select the correct sound insulation partition

When choosing one or another type of partition, the question inevitably arises: which partitions have the best sound insulation characteristics with the smallest thickness, mass and value? The traditional answer sounds like this:

Multilayer frame partitions as internal enclosing structures are preferable. With a much smaller mass (which is very important to reduce loads on overlapping and the foundation) and the thickness, they have almost the same, and sometimes greater, air noise isolation index (RW) than single-layer structures.

Table 1 Comparison of sound insulation partitions

Soundproof design	Thickness	RW
Wall in Polkirpich (thickness with plaster 150 mm)	150 mm	47 dB.
Wall in one brick (thickness with plaster 280 mm)	280 mm	54 dB.
Wall in two bricks (thickness with plaster 530 mm)	530 mm	60 dB.
Soundproofing frame partition on a frame of 50 mm	108 mm	56 dB.
Sound insulation frame partition on a frame of 100 mm	158 mm	61 dB.
Soundproof frame partition on double frame 2x50mm	168 mm	65 dB.
Soundproof frame partition on double frame 2x100mm	268 mm	68 dB.

Note! For the isolation of interroom "household" noise, it is more preferable to use the structure of a light partition with a thickness of 108 mm, having a level of noise insulation, comparable in magnitude with sound insulation of a substantially more massive and thick wall with a thickness of 280 mm.

In our table, for comparing the sound insulation properties of partitions, we use the RW air noise insulation index. Despite some disadvantages, it is a very convenient parameter for a quick comparison of sound insulation of various partition structures among themselves and with the regulatory values \u200b\u200bof sound insulation of enclosing structures. In the territory of the Russian Federation since 2012, there is an updated edition of SNiP 23-03-2003 "Noise Protection", according to which the soundproofing of the ed-military wall in a residential building should be at least 52 dB (RW), and partitions between the adjacent rooms of the same apartment - not meee 43 dB.

As "sanitary standards", these numbers can still be consistent, but for truly comfortable living in the conditions of increased noise levels in modern housing they are clearly insufficient. Noise background in apartments, not even considering powerful sources, such as home theaters or Hi-end systems, over the past decades, we have grown in our country. Currently, in almost every house and each room has a TV, telephone, radio, and in the kitchen and bathrooms are washing or dishwasher, extractor, air conditioning, etc. The home computer also contributes to an increase in the overall noise background.

The existing experience suggests that for modern conditions, the air noise insulation index of the interroom partition should be at least RW \u003d 50 dB, and the ed-military wall is not less rw \u003d 60 dB. Only with such regulatory values \u200b\u200bof the enclosing structures can actually talk about acoustic comfort. However, even the wall with RW \u003d 60 dB will not fully solve the problem of sound insulation of the bedroom, if the neighbor's neighbor decided to see the new fighter in his home theater at night.

It is interesting that noise penetrating the streets through the open windows, causes much less irritation, the weaker sounds: music, screams, laughter, distinguished from the next apartment. Noise of vehicles, as well as the gross thunder, and behind the common buzzment is not worth an evil will of a particular person, while the neighbor behind the wall is preventing their TV - the person is known and clearly unpleasant ... Therefore, the domestic noise is much smaller intensity well the ear and the brain. This is due to the psychophysiological features of human hearing and psyche, and in the struggle for acoustic comfort, the dwellings with this also have to be considered.

Device of sound insulation partition

Below is the composition of the design of the soundproofing partition, which has the maximum acoustic properties with the minimum possible thickness on today. Such design easily provide an air noise insulation index from 56 to 62 dB.

First of all, these are light frame partitions on a metal frame. Interest represents the design on an acoustic profile with a thickness of 100 mm, sheathed from two sides by sheets of acoustic triplex and leaning gypsum Gyproc Aku-Line. It is time to tell about the advantages of the acoustic triplex Soundline DB and the rack metal profile of the vibrooflex-wave.

This is not only perfect for interior walls, but it can even be used as an ed-road partition for the most demanding customers. This design has a thickness of 158 mm. For those who need to do thinner - there is an option on a 50 mm profile, which also provides isolation is also quite good for interior partition - RW \u003d 56 dB with a thickness of 108 mm.

The overall effect of sound insulation of the partition also depends on the selection of the medium layer material. The main criterion for choosing such a material is the value of its dimensionless coefficient of the sound absorption α W, the values \u200b\u200bof which can vary from 0 to 1. The closer the value of α W to one, the higher the sound absorbing capacity of the material. To obtain the maximum effect, it is recommended to choose materials with α w at least 0.8. For example, a special sound-absorbing material - the acoustic mineral plate of class premium shumnet-bm is α w \u003d 0.95.

The thickness of the absorbing layer should be at least 50% of the internal space of the partition and be not thinner than 100 mm (it is natural that only one layer of the sound absorber with a thickness of 50 mm can be applied with a thickness of 50-75 mm).

To achieve the stated sound insulation indicators of partitions, the accuracy of the installation of such structures is of principle. The framework elements associated with the side walls and overlaps should be isolated with elastic pads of vibrastek-M, and the joints after installation are sealed with a sealant vibrating to eliminate indirect transmission of sound. Detailed schemes of data of these partitions with a list of necessary items are given in the album of engineering solutions Acoustic groups, ASP-401-0915 cipher.
