Today, an increasingly relevant problem is the soundproofing of the premises. Especially acute this question arises in large cities, where there is a huge number of different sources of noise, with it, it grows every day. At the same time, the demand for high-quality sound insulation materials is increasing.

In a modern fussy world, the opportunity to stay in silence and tranquility - luxury, not available to everyone. From the sounds from the street almost always be able to protect high-quality windows (how to choose them, we wrote in previous articles), but to get rid of the invisible "presence" of the neighbors - the task is not the lungs. Night crying of children, a loud birthday celebration, singing in the shower and much more can be not just sources of irritation. If it is impossible to relax in his own home, even health problems can occur - chronic fatigue and neurosis. In addition, it is impossible to fully enjoy beautiful loud music or film in the home theater, without fear of disturbing anyone.

The output is one - to spend high-quality sound insulation, with what, with your own hands it is quite possible. Today, the market presents a wide range of this product, so the modern consumer can be very difficult to independently understand all the nuances and technical and performance characteristics of this category of goods. How to choose sound insulation materials, which is better and more efficient in a specific situation, as well as what comparative characteristics have it, this material will help to disassemble.

Choose them to solve specific technological tasks - depending on the type of noise, the functional purpose of buildings and operational requirements. Under conditions of apartment buildings, partitions and bearing walls are just a conditional obstacle to propagate sound waves. However, in order to obtain complete independence from noise, do not disturb the neighbors, the problem can be very easy to solve - you need to spend high-quality sound insulation.

First you need to decide on the type of noise that affect. They allocate three general groups:

• Air noises - they spread through the air. If the obstacle in the form of walls, partitions or overlaps is found on the path of the sound wave, it does not go out, but it causes oscillations. They are transmitted to air particles in the neighboring rooms, so we hear sounds. Examples of such noise can be a working loud receiver, conversations of neighbors, crying baby, and so on. High-quality soundproofing material is able to repay oscillations, helping to eliminate the problem;
• Impact noise - occur during mechanical impacts on the design. It can be a rearrangement of furniture, drop items on the floor, blows and much more. Then noise insulation must be subjected to floors and ceilings;
• Structural noise - in this case, the sounds apply to building designs. From such noise it is the harder to get rid of everything, only complete sound insulation of the entire apartment will help here.

There is also complete and local soundproofing. The last method involves insulation from noise of particularly weak points.

Soundproofing Material Review

Sound waves, which are manufactured as sources within the house and beyond, are distributed to all the designs fixed with each other. As a result, the sound that occurs in one place is often heard in the other, tolerated throughout the building. It can be protected from it not only in a closed, provided with high-quality insulation of the room, but also a properly designed open space.

The main parameters that determine the sound insulation properties of materials are IV - the insulation index from air noise, as well as the IU, the index of the reduced level of shock noise under the overlapping. In European countries, another designation of parameters IV and IU is, respectively, RW and LN, W. Indices IV and IU can be counted in RW and LN, W according to formulas: RW - I + 2 (dB), LN, W - IU - 7 (dB).

In the modern construction sphere, such types of sound insulation materials are most popular and common, according to the generally accepted classification:

• Mineral wool;
• Polystyrene foam;
• Viscoelastic membranes;
• Foamed polymers;
• Sandwich panels;
• Natural plug;
• Cellulosic materials (eco);
• Foam glass;
• Rubber sound insulators;
• Noise insulating substrates.

Each of them is worth a detailed consideration, as it has a number of benefits and restrictions.

Minvata One of the most common materials to date is mineral wool. It greatly absorbs sounds - with both shock and aerial origin. These characteristics allow it to remain the most demanded material for these purposes. Special plates or mats are used for work, made on the basis of acoustic mineral wool.

Such products are characterized by high sound insulation indicators that are achieved due to the special location of the fibers. The structure creates open air cavities that perfectly quench sound fluctuations. Due to this, mineral wool is distinguished by the excellent ability of sound insulation, differing in this low dynamic rigidity. A very important indicator of the effectiveness of noise insulation is the sound-absorption coefficient AP, which depends on whether the wool is glued to the surface or separated by airspace, whether there are facing materials from above. In addition, the sound absorption coefficient AP depends on the thickness of the material. As a rule, it is in the range from 0.75 to 1.

Polyuretomol - the second most popular material for these goals. However, it is able to absorb exclusively the sounds of shock origin, with that it gets the optimal properties of noise insulation, it must be slightly pressed so that the structure is compressed. But despite this, the material is extremely common. Due to such specific parameters, expanded polystyrene is used mainly to ensure the insulation of floors - floors and ceilings. If you put on the floor, it is possible to squeeze it perfectly well by filling a concrete screed with a thickness of 3-6 cm.

Reinforcement of the screed makes it possible to protect it from cracking as a result of movements on a deformed basis - under the influence of such a load, the height of the material is reduced by 2-4 mm, the granules are compressed, providing excellent suppression of drum noise in the range of 25-33 dB.

Stop material is needed on an even base, close to each other. The seams are shut off on half the length of the plate, and the seams on the edge are usually performed from the same material. Before filling the screed, the separating layer of film material or rubberoid is placed on the polystyrene foam base. For sound insulation, a small thickness plates are perfect - up to 4 cm.

Membranes. As for viscoelastic membranes, they also seem to be very comfortable for sound insulation. They are used, as a rule, to increase the protection of frame walls from outsided sounds. However, viscoelastic membranes are also manufactured for:

• walls;
• ceilings;
• floors;
• roofing;
• engineering communications.

They are highly discovered synthetic sound insulation materials made of polymers without the use of bitumen resins and rubber. They are distinguished by high indicators of elasticity, flexibility, strength, durability and fire resistance. It is also used as vibration-absorbing medium layers to increase sound insulation of frame walls and prevent the appearance of resonant effects. The viscolastic membrane is pasted on plasterboard sheets from the inside of the carrier frame. The use of such materials makes it possible to increase protection against extraneous sounds by 25-32 dB.

Polyurethane. To sound insulation of individual parts of the apartment - bathroom, toilet, kitchen, living room and others are also often used polyurethane. As a rule, foamed polymers are used in studio premises, as the easiest way to ensure sound insulation of walls, ceilings and partitions between adjacent apartments or rooms.

Panels. Recently, a high popularity on the market of soundproofing materials began to purchase a sandwich panel. They can be completely different in length and composition, are used, as a rule, for sound insulation of single-layer partitions. Today, it is increasingly often for the creation of additional protection of single-layer partitions (for example, brick walls) from the sound waves began to use the soundproofing systems of the finished type. This is a sandwich panel of different thicknesses, which consist of a combination of materials of various density and structural characteristics. The advantages of their use include the absence of the need to mount a metal frame - they are attached directly to the walls.

One of the most popular options is the combination of a dense layer (gypsumless sheet) and light (mineral wool) - the thickness and structure of materials may vary. They are mounted using vibration-insulating materials through special nodes manufactured by the manufacturer. The thickness of such panels can be from 40 to 150 mm, and is selected, based on the thickness of the carrier partition. An increase in the sound insulation index depends on the density and can be from 10 to 20 dB.

It is also possible to use triplex panels in the form of durable multilayer cellulose frames with mineral fillers, in which specially selected mineralogical compositions are used. They are mounted to the walls with the help of dowels (possibly to the crate), and also fit into the floor, replacing floating floors and cement ties. Each of the layers of the frame has its own indicators of repeated reflection and dispersion of sound waves, which makes it possible to achieve a reduction in aerial noise to 37 dB with a thickness of a 10 mm material.

Bung. Natural cork materials are very long been used to create high-quality sound insulation of premises, however, thanks to the development of modern technologies, the sound-absorbing quality of cork coatings are constantly improving. And, if a technical stopper was used with a grain size of 5-8 mm, today it is manufactured with the best sound insulation indicators, which are provided with smaller dimensions - 1-3 mm, but the air emptiness is 3 times more.

Equata. Emota-based cellulose insulation are also well used as a sound insulation material - at the same time they can be used for different types of noise and different premises. The material is obtained in the process of recycling secondary raw materials - waste paper. It consists by 80% of secondary cellulose, 15% - antiseptics, and 5% -antpyrine. It is applied not only for insulation, but also suppressing air noise:

• on floors that share non-exploited attics;
• filling the frame walls and partitions.

Soundproofing characteristics are equated with the structural features of the material - there is a large number of fibers separated by airspace. It blends with the help of special equipment and, depending on the place of use, it is placed in layers of different density.

Foamglass. The material is distinguished by high technical and operational characteristics - high strength, resistance to the effects of aggressive chemical compounds, fire safety, simplicity of treatment, thanks to which the material has gained tremendous popularity in European countries. The plates from the foam glass are very easy to cut - they can be mounted both outside (stacked as an average layer of insulating "cake") and indoors. In addition, they can serve to build light inland partitions. The stove is thick 10 cm. Provides protection against sound insulation up to 30 dB.

Rubber. Soundproofing materials made on the basis of rubber are perfectly used to absorb shock types of noise. Very often used for industrial premises, however, residential buildings can also be isolated with their help. Move from recycled rubber (sometimes - with the addition of traffic jam).

Very often used as sound insulation under the appliances appliances, the work of which is accompanied by the appearance of vibration waves (washing and dishwashers). They can also be used directly under floor coatings, under floating tie or concrete slabs, as well as under rigid floor elements on a wooden base.

Manufacturers offer materials for various types of flooring: parquets, parquet boards, laminates, carpet, linoleums and even ceramic tiles. When installing, it is necessary to control so that no cracks remain - all layers must be tightly fixed to each other, otherwise acoustic bridges, worsening the design parameters arise. Allows reduced shock noises to 15-33 dB.

Substrates. The peculiarity of the substrate under the floor covering is that they suppress the shock, but not air noise. However, they will be indispensable for laying under laminate and parquet, especially if the design of these flooring does not provide a layer of sound absorber. Allows you to prevent the appearance of deaf noise, which are accompanied in the process of walking on the floor, and which are audible in the rooms below. Soundproofing substrates can be represented as:

• Elastic mats of polyethylene foam 4 mm thick, which level the irregularities of the grounds, prevent the spread of impact noise and the occurrence of sound bridges;
• Wardrobe plates made from compressed wood fibers. They are light and porous, represent a smooth and elastic basis for flooring;
• Cork mats with compressibility and elasticity that do not absorb water and not aging;
• Corrugated cardboard, which perfectly suppresses noise and does not miss water vapors, while not compressing;
• Tuplex mats, the thickness of which is about 3 mm - they are a two-layer polyethylene film of heterogeneous composition, separated by a layer of polystyrene foam granules that are recessed in the glue. Excellent fit for laying under wooden flooring or floors from panels. Different with high noise suppression abilities - 17 dB. This material has moisture protection properties, so when it is laying it does not require the use of vapor barrier.
• Polyurethane foam mats, depending on the type of which can be used for styling for elastic coatings on glue, linoleums, as well as under glued and freely mounted rubber or carpet materials. They can also be laid on the bearing structures of overlaps, on seamless, spacious milking floors, PVC coatings, on floors of stone and ceramic tiles covered with varnish parquets. The thickness of the mats is 2.5 mm, and the ability to suppress noise - 17-19 dB. Polyurethane foam mats improve noise insulation by 23 dB.

Special attention deserved fasteners on which sound insulation is carried out. As a rule, for these purposes it is necessary to mount frame drywall structures on the walls and the ceiling. However, the presence of rigid fixation between the protected surfaces and the metal frame in the form of standard metal suspension and brackets leads to the fact that even taking into account the use of pads, the noise is transferred to the facing and then in the room.

Soundproofing Materials: Table

To solve this problem, it is necessary to apply special soundproofing fasteners, which are strong enough, but at the same time plastic, and also have soundproofing characteristics in a wide frequency range. Fastenings have a large number of varieties, they differ in the application area, structural features and type of an elastic element used.

However, sound insulation can be not only solid - there is also local insulation. In addition, it is very often for protection not from external sound waves, but on the contrary - it is necessary to protect the neighboring rooms from sounds, in such cases an acoustic insulation is made.

Local sound insulation

All since childhood know "spyware" ways of listening to neighbors through sockets. As a rule, these elements between different apartments are made through, and the builders are not that they do not equip them with sound insulation, but do not even put partitions. In such cases, you can simply call an electrician or eliminate the problem yourself, observing the rules and safety equipment when working with electricity.

To do this, you need to de-energize the outlet, take it out and then get the mounting box. The hole must be sealing with cement or mounting putty, after drying, you can mount the outlet in place. This method allows you to eliminate another source of local noise penetration - junction boxes. As a rule, they are located in the walls or under the ceiling, hidden under wallpaper or other finishing material. They are very easy to find, just looking around the wall, although in this case it is best to use the services of professionals, as there are a large number of electrical cables.

Another source of local noise can serve the risers of water supply, heating and sewage. Their sound insulation should be carried out at the construction stage - the sleeves are inserted into the overlap, the size of the size is inserted, and the space between them is filled with non-flammable sound insulation material. From above it is sealed with a special plastic sealant (how to choose it, read in the material about sealants). However, in practice, the situation is completely opposite - the pipes are simply carried through overlaps, and the gaps close up with the help of a simple cement, which does not just perfectly conduct sound waves, and over time cracks and collapses.

To eliminate this drawback, it is necessary to produce as a deep clearance of the old cement as possible, wrap the pipe with a sound insulation material, to cement a dismantled section of the overlap, and the joints themselves are blended.

The last point of local noise insulation is to eliminate deep cracks between partitions and walls. To create obstacles for sound waves, you can fill the seams with plaster plaster, cement or plastic sealant.

Acoustic insulation

In most modern premises, the provision of a comfortable acoustic environment is one of the main functional requirements (for example, for cinemas, concert, multidisciplinary and conference rooms, office space and others).

The acoustic characteristics of the premises significantly affect the nature of the sound playback in them. That is why structures that are intended, for example, for lectures and concerts, should have different acoustic parameters.

One of the main criteria that characterize the acoustic quality of the premises is reverberation indicators (RT60). At large values, the perception of sounds is distorted, the indicators of speech intelligibility decrease, with very small - the effects of "lifeless" of premises, "dryness" of reproducible sound effects appear. Provide optimal reverb indicators (or adjust them) in most cases enable modern acoustic materials and structures, with which high sound absorption indicators are provided.

To ensure optimal absorption of sounds, the highest attention should be paid to the ceiling space. Therefore, the "acoustic" ceilings, which absorb sounds, have been made for quite a long time. In large buildings, where to improve acoustics, it is notated by one only ceiling space, it is recommended to apply special sound-absorbing panels for walls.

The technical and operational characteristics of ceiling and wall sound-absorbing panels include: acoustic and hygienic parameters, moisture resistance, fire and technical parameters, impact resistance, lighting characteristics and duration of operation. To date, there are a large number of materials that are suitable for solutions not one technological task, but a whole complex of requirements, for example, to ensure the necessary acoustic parameters in rooms with high humidity - in the pools. In fact, the system data also perform both artistic functions for interior design.

The choice of materials for ceilings or walls depends on various parameters: the functionality of the premises, their volumes, the cost of materials, design features, and others, as well as from what kind of frequency range must be corrected. By absorption characteristics, they can be divided into: medium and high-frequency absorbers, as well as low-frequency absorbers;

To the first type can be attributed:

• porous plates;
• fibrous materials that can be made in the form of plates from mineral or glass wool, artificial or wood fibers. The facial part can be processed by special porous coloring compositions and covered with cloth;

Low-frequency absorbing materials can be represented as thin panels with different perforations that can be produced from plaster plates, MDF, wood and other materials. Low-frequency absorbers can be attributed to the low-frequency constructions from porous fibrous materials, with perforated-tissue screens and air gaps.

The modern market of sound insulation materials is represented by a large assortment of products, among which everyone can choose the necessary - in full compliance with the technical and operational requirements that make the features of editing. In this material, all materials were described in detail, as well as the features of their use.

With the development of modern technologies, the frequency range of sound sources has expanded significantly. Especially from this suffer from residents of panel and block high-rise buildings. Contrary to common myths, traditional insulation, such as mineral wool, foam or traffic jams, do not help enhance sound insulation. To fully protect your apartment from the penetration of noise, you should look for a comprehensive solution and it is best to invite acoustics engineer for this. This is recommended to act in case of serious acoustic discomfort. If it is necessary to reduce the noise pollution by 5-10 dB, you can resort to special noise insulating materials by applying them in the design of frame partitions and wall cladding. This rating contains a list of the most effective and compiled on the basis of expert opinions and user reviews.

The real characteristics of noise insulation may differ from the manufacturer declared, since largely depend on the degree of tightness of the fences, their total mass and the number of layers, as well as some architectural aspects. In other words, even the most effective material will be useless if the apartment is located near the noisy engineering equipment, a neighbor's subwoofer rinsing regularly through the wall, and the partitions are made in the form of single structures and are rigidly attached to the bases. In order to prevent vain spending of time and money, we suggest evaluating the pros and cons of different materials.

Conclusions: Materials providing complete noise insulation does not exist. To maximize the sound when penetrating it through the wall, it is necessary to build a sound insulation design of the type "Mass-elasticity".

Rating (2019): 4.9

The acoustic Triplex Soundline-DB has unique sound insulation properties. It is made on the principle of automot windshield. There is a special sealant between two moisture-resistant leaning sheets of plasterboard (8 mm). Due to the elasticity of the layer there is a decrease in the sound flow due to the phased absorption of the waves. In other words, each sheet of drywall fluctuates itself. The total noise insulation is obtained significantly higher than that of the same two sheets of plasterboard without acoustic layers.

The testing of the material has shown that it has the lowest inflammability, toxicity, flammability, and smoke formation. Triplex Soundline-DB fully meets all the requirements of the sanitary and hygienic standards of the Customs Union.

Among the advantages of noise insulation should be noted the simplicity of installation, a high degree of sound insulation (up to 69 dB), maintaining its properties up to 25 years, a small cost.

Triplex installation is largely similar to the creation of plasterboard structures. It is only necessary to choose the corresponding screws under the thickness of the sound insulation (17.5 mm). Also should be corrected for the high weight of the three-layer canvas.

Owners of houses and apartments in the reviews praise soundproofing qualities of the Soundline-DB triplex. It is easy to install, effective when dealing with noise, has a small thickness. Of the disadvantages, you can mark high weight and bulky.

1 ZIPS-III-Ultra

Best Sandwich Panel
Country Russia
The average price: 1525 rubles.
Rating (2019): 4.9

The use of the SIPS-III-ultra sandwich panel allows you to comprehensively solve problems associated with extraneous noise. Thanks to the exact size of the sheet (1200x600x42 mm), any homeowner will quickly consider the need for a particular room. It is also worth considering that the kit comes in the kit the necessary set of hardware for fasteners. These are traditional dowels, anchors, washers and self-tapping screws. The noise insulating system itself is a combination of gypsum and staple glass fiber. The role of support is played by 8 vibration insulators. They protrude in a free state of 10 mm in relation to the sheet plane. In the installation process, they are driving with drywall. As a result, the total soundproofing thickness and drywall sheet is 55 mm.

For the device of the noise insulating layer on the walls, it is necessary to stock only a perforator, a screwdriver and hacksaw. Thanks to the frameless system, it will be possible to save on the crate. An understandable installation instruction is attached to the sandwich panel. The layer of noise insulation can be closed by conventional plasterboard sheets.

Domestic owners of apartments and houses call the Zipse-III-ultra panel with the best sound insulation. It is effective, inexpensive and thin. After the device noise insulation, many managed to forget about the loud neighbors, their dogs and sounds from a busy street.

Soundproofing is measured in decibels, the term is used when it comes to reducing the volume of the outgoing / incoming noise.

Sound absorption is estimated by the calculation of the sound absorption coefficient and is measured from 0 to 1 (the closer to 1, the better). Sound-absorbing materials absorb the sound indoors and quench, as a result, the echo disappears.

If you need to get rid of the noise of neighbors - you need soundproofing materials. If you need the absence of echo indoors - sound absorbing.

How to reduce the noise of neighbors on top / bottom / behind the wall? Can I get rid of them from my noise?

Soundproofing the ceiling is a deliberately losing option. Maximum can achieve a decrease of 3 to 9 dB. Try to agree with the neighbors and make them the soundproofing of the floor, then you will achieve a decline of up to 25-30 dB!

Soundproofing the wall depends on the type of wall. They or erected, or already existing (between rooms and apartments). For the erected walls immediately make double, independent frames. The thicker and the multilayer wall, the higher the chance to achieve noise reduction by 50-60 dB in the apartment.

For existing walls - either make a frame with soundproofing materials, but get ready for "Eat" 10 cm. Spaces. Either, if there is little space, secure soundproofing panels or roll material directly on the wall.

For the sound insulation of the floor, lay the Topsilent Duo or Fonostop Bar. If there is no possibility to raise the floor under the tie 10 cm, then lay soundproofing materials under the floor covering. Note, noise in this case will decrease no more than 10-15 dB.

Try to the screed and flooring do not come into contact with the walls of the premises. "Floating" design provides the best sound insulation properties. Conversely, if the soundproofing layer climbs on the walls of a pair of centimeters, it will additionally extinguish sound waves.

Made a repair, did not think about the sound insulation and now hear the noise of neighbors, how to fix?

Unfortunately, you will have to make edits in the already made repairs.

If there is a sound insulation of the floor, remove the laminate (or another fine coating) and put the Fonostop Duo soundproof membrane under it.

If the walls, then as mentioned above, the coating should be removed, make a frame and glue the Topsilent Bitex type material. Similar to the ceiling.

What materials are used for soundproofing apartments? How much do they need? How to calculate the required amount?

For sound insulation, an integrated approach is necessary. The design, "sandwich" from several materials is collected. The thickness of the quality design is about 7-10 centimeters.

To calculate the required quantity, send the size of the room - length, width and height, the manager will make the calculation and tell what materials will be needed.

What materials are needed for recording studio?

For recording studios, both types of materials are important and sound-absorbing. First of all, high-quality sound in the studio is achieved through the use of sound-absorbing, acoustic panels of foamed melamine or polyurethane with open cells. The cellular structure of the material "quit" sound oscillations. We recommend using thick panels up to 100 mm, it will ensure the absorption of sound in a wide range of frequencies. In addition, install "bass traps" thickness up to 200-230 mm.

With sound insulation, everything is simple - more layers and it is desirable to use two-layer materials with a lead layer, for example, Akustik Metal Slik.

What sound insulation is better?

The best material is the one who will solve the task. Some and the same sound insulation materials manifest themselves depending on the volume, such as walls, the ceiling of the room. We recommend consultation with a specialist before starting repair.

How is the installation of sound insulation and sound-absorbing materials?

The easiest to attach sound-absorbing acoustic panels. Take the glue of any type and attach where necessary. The material is lightweight and easily grasped with the surface.

For the installation of sound insulation materials, specially intended adhesives are used - Ottocoll P270 (for the floor) and Fonocoll (for walls and ceiling).

Deliver materials? Is there a pickup?

Yes, deliver. Choose a convenient way of delivery: self-delivery from a warehouse in Lyubertsy, Delivery by Van within the Moscow Ring Road and Moscow region (up to 100 km) or a transport company if you are far from Moscow.

Where to see prices?

The price for sound insulation and sound-absorbing materials is in the "Price List" section.

The main feature of acoustic materials is high porosity (up to 98%). The structure of them is cellular, grainy, fibrous, lamellar or mixed. The pore value varies widely and usually does not exceed 3-5 mm. Porosity can be adjusted within certain limits, changing the effect of technological factors in production, thereby you can get materials with specified properties: medium density and thermal conductivity coefficient.

High porosity is obtained by ways: gas formation, high water intake, mechanical dispersion, creating a fibrous frame, swelling of mineral and organic raw materials, burning additives and chemical recycling.

The classification of acoustic materials is built on the principle of functional purpose of these materials. According to this principle, they are divided into:

- sound-absorbing intended for use in the structures of sound-absorbing lines of interior and for individual sound absorbers to reduce sound pressure in the premises of industrial and public buildings;

- sound-insulating used as gaskets (ground) in multilayer enclosing structures to improve the isolation of fences from shock and air sounds;

- vibrating absorbing intended for the weakening of bending oscillations propagating in rigid structures (mostly thin) to reduce the sound emitted by them.

Sound-absorbing materials in accordance with the current standard are classified according to the following basic signs: efficacy, form, rigidity (relative compression), structure and ignition.

In the form of sound-absorbing materials and products divided:

For piece (blocks, plates);

Rolled (mats, strip pads, canvas);

Loose and bulk (mineral and glass wool and glass, crumples, muttered perlite and other porous grainy materials).

By hardness These materials and products are divided into soft, semi-rigid, hard and solid.

According to structural features, sound-absorbing materials and products are subdivided on porous fibrous, porous-cellular (from cellular concrete and perlite) and porous spongy (foams, rubber).

According to ignition, like all building materials, acoustic materials and products are divided into three groups: non-aggravated, challenged and combustible.

Comparing the classification signs of sound-absorbing, as well as thermal insulation materials and products, you can see their commonality, which once again underlines the identity of tasks in the manufacture of these materials. However, it should be noted that in order to give high indicators of the functional properties to the materials and products under consideration, it is necessary to use various technological methods, allowing to form a porous structure necessary for one or another case.

By efficiency, sound-absorbing materials and products are divided into three classes:

1st grade - Over 0.8;

2nd class - from 0.8 to 0.4;

3rd grade - from 0.4 to 0.2.

Soundproofing materials are divided into piece (tape, strip and piece pads, mats, stoves) and loose (clay, domain slag, sand).

By structure, soundproofing products (materials) are divided into:

Pattern-fibrous made of mineral and glass wool in the form of soft, semi-rigid and rigid laying products with an average density of 75 to 175 kg / m 3 and a dynamic modulus of elasticity no more than E (W) \u003d 0.5 MPa with a load of 0.002 MPa;

Poros-sponge, made of foam and porous rubber and characterized by E (W) from 1.0 to 5.0 MPa.

The dynamic modulus of elasticity of grainy snowflows should not exceed E (W) \u003d 15 MPa.

Dynamic elastic module E (W). The module determined by the ratio by the ratio to the part of the deformation, which is a syphneen voltage. Corresponds to expression

E (W) \u003d EN - (EN - E p) / (1 + (W T2),

Thus, sound-absorbing and sound insulation materials must have an increased ability to absorb and disperse sound waves.

In addition, sound-absorbing and sound insulation materials and products must have stable physicomechanical and acoustic properties during the entire period of operation, be bio and moisture-resistant, not to allocate harmful substances into the environment.

Sound-absorbing products, as a rule, should have high decorative properties, as they are simultaneously used to finish the internal surfaces of building fences.

Sound insulation laying materials and products of porous fibrous structure from different wools of soft, semi-rigid and hard species with e no more than 0.5 MPa or 5 · 10 5 N / m 2 have a load on the sound insulation layer 0.002 MPa (2 · 10 3 N / m 2).

Soundproofing materials apply:

In floors - in the form of continuous loaded or unloaded (carriers of only their own mass) of gaskets, piece loaded and strip loaded gaskets;

In partitions and walls - in the form of a solid unloaded laying in the joints of the structures.

Vibrating absorbing materials. Vibrating absorbing materials are designed to absorb vibration and caused noise when working engineering and sanitary equipment.

Vibrating absorbing materials serve some grades of rubber and mastic, pholoisol, sheet plastics. Vibrating-absorbing materials are applied to thin metal surfaces, with an effective vibrating absorbing design with high friction energy.

To eliminate shock sound transmission, the designs of "floating" floors are used.

Elastic gaskets are stacked between the bearing slab overlap and clean floors. It is also necessary to separate the design of the floor from the walls along the perimeter of the room. The species and properties of some sound insulation pads are presented in Table. 3.

Effective sound insulation materials are semi-rigid mineral wool and glass on the synthetic binder plate and mats, as well as firmware glass mats, tree fiber plates, porous rubber, polyvinyl chloride and polyurethane foams. Ribbon and strip pads are made with a length of 1000 to 3000 mm and a width of 100, 150, 200 mm, piece gaskets - a length and width of 100, 150, 200 mm. Products made of fibrous materials are used only in the shell of waterproof paper, films, foils.

Acoustic panels . Structurally, the acoustic panels are also arranged as the usual wall panels, except that one of the plates of the panel has perforation.

Fig.12.1 Acoustic Sandwich Panel

Perforation of metal plates in acoustic sandwich panels allows you to increase the sound-absorbing properties of the panels, and also gives panels an additional decorative effect. Percentage of perforation and diameter of the holes of perforated sheets meets the requirements of GOST 23499-79 "Materials and products of construction sound-absorbing and sound insulation. Classification and general technical requirements. "

Percentage of perforation, not less - 20; The diameter of the holes, mm. - four.

Application of acoustic sandwich - panels:

For the construction of enclosing structures, ceilings, inner walls and partitions in industrial buildings and structures, which requires protection against the influence of industrial noise;

For the construction of soundproofing screens (including mobile) on the territory of residential building in order to reduce noise pollution;

For the construction of noise protection screens on automotive and railway highways in an urban feature, near settlements and protected areas;

Protection against noise diesel generators, soundproofing of chiller installations, sound insulation of transformer substations.

Soundproofing and noise insulation of a common wall . Street noise can pass through the general wall of adjacent houses, sound insulation of the common wall can be improved, but the effectiveness will depend on the design of the wall, the presence of a fireplace and an electrical equipment located on it.

Photo. 12.1 Mineral wool and plasterboard plates

The second method of sound insulation of the common wall includes a plane acoustic mineral wool and a double drywall cladding on metal placters.

With this method, the sound does not pass directly, but dissipates.

It is initially a doomer is organized, for which there are 50x50 mm, with a distance between them a little less than 600 mm, so that roll-insulation from mineral wool 50 mm thick. Tightly adjacent to the obreshetam and to the wall.

Further, at a distance of 100 mm from the floor, across the crates are attached to the elastic slats in the horizontal position across Oberesten, the distance between the planks from 400 to 600 mm, the latter bar is attached at a distance of 50 mm from the ceiling.

The wall is faced with an acoustic drywall of 19 mm thick, for fastening the panels to the planks, screws are used 32 mm long, they must pass through the bar, but do not touch the wall or oblashetin.

It is necessary to leave a gap around the room perimeter from 3 to 5 mm. On top of the first layer of plasterboard, a second layer of 12.5 mm thick is mounted, the joints must be shifted relative to the first layer.

With the help of sound-absorbing sealant, the gaps are closed and the plinth is installed.

Select sound-absorbing material. Instruments that make it possible to effectively regulate the acoustics of the room, are decorative and finishing sound-absorbing materials and structures. At the same time, sound insulation materials must perform two main functions - to prevent the oscillations of the sound wave of the barrier (for example, the interroom partition), as well as, if possible, absorb and dispel the sound wave. In principle, all listed materials are recommended for use as sound insulation of office space. But I would like to stay on some nuances. More recently, the cork cover was very widely used as a sound insulator. However, according to specialists, in fact, the plug is effective only against the so-called "shock noise" (resulting from a mechanical impact on elements of building structures), and does not have universal sound insulation characteristics. The same applies to various synthetic foam materials. They are quite attractive from the point of view of ease of use, but for the most part do not meet the modern requirements for soundproofing public buildings, and in addition, often do not meet the requirements of fire safety. Therefore, universal sound insulation materials based on natural raw materials are currently overlooking the foreground, for example, stone wool-based products. Their excellent sound insulation properties determines the specific structure - chaotic directed thin fibers when friction convert the energy of sound oscillations into thermal. The use of such insulation significantly reduces the risk of vertical sound waves between the wall surfaces, reducing the reverb time, and, thereby, reducing the sound level in the adjacent rooms.

FROM pecial to provide acoustic complex in their own house, in public places, at the workplace Rockwool has developed a new product - sound-absorbing plates from stone wool Acoustic Batts.

In the form of plates of various thicknesses, they are used to sound insulation of the premises of all types. Among them are universal materials to enhance the soundproofing of walls, gender and ceilings. For example, Rockwool acoustics batts with a density of 40 kg / m 3; Designs using the sound insulation index to 60 dB.

1. Plasterboard sheet; 2. Ceiling profile; 3. Profile guide; 4. Suspension straight; 5. Tape sealing; 6. Dowel; 7. Self-tapping screw; 8. screw self-tapping; 9. Acoustic Batts.

The plates plated between the rated frames of the framework of plasterboard walls are noticeably increased by the sound insulation index of interior partitions in the office or apartment.

They are also used when creating floor on reinforced concrete or beam overlap. For the sound insulation of the ceiling, the material can be mounted directly to the overlap under the surface of the suspended or stretch ceilings.

Non-combustible stone fiber material Capable to withstand, without melting, the temperature is over 1000 ° C. While the binding component evaporates at a temperature of 250 ° C, the fibers remain intact, associated with each other, while maintaining its strength and providing protection against fire. Rockwool products are non-combustible material (fire hazard class KMO). This property allows you to prevent the dissemination of the flame during fires, as well as at a certain time to delay the destruction of the supporting structures of buildings.

D. additional insulation from the air noise of inter-storey floors over the reinforced concrete plate.

Stability to deformations. This is, above all, the lack of shrinkage throughout the life of the material. If the material is not able to maintain the necessary thickness in mechanical effects, its insulating properties are lost. Part of the fibers of our material is vertically, as a result of which the overall structure does not have a certain direction, which ensures high rigidity of the heat-insulating material.

Soundproofing. Due to its structure - an open porous structure - stone wool has excellent acoustic properties: improves the air sound insulation of the room, sound-absorbing properties of the structure, reduces the time of reverb, and, thus, reduces the sound level of noise in adjacent rooms.

Waterproofing and vapor permeability . Stone wool has excellent water repellent properties, which, together with excellent vapor permeability, makes it easy and efficient to remove pairs from the premises and designs to the street. These properties allow you to create a favorable internal climate of the premises, as well as the whole structure as a whole and thermal insulation in particular to work in a dry state. After all, as you know, moisture is well spent warm. Finding into thermal insulation material, it fills air pores. At the same time, the heat shield properties of wet material deteriorate significantly. And the moisture that fell on the surface of the material does not penetrate into its thickness, so that it remains dry, retains its high heat shielding properties.

Plates "ACINIT" and "AMGRAN" - Acoustic materials made on the basis of granulated mineral wool and compositions of starch-binding with additives. The plates are produced in size than 300x300x20 mm, a density of 350 ... 400 kg / m 3 and the limit of tensile with bending 0.7 ... 1.0 MPa, with a high sound absorption coefficient - to 0.8. These plates are designed for sound-absorbing trimming of ceilings and top of the walls of rooms, public and administrative buildings operated with relative humidity of no more than 70%. The front surface of the plates has a texture in the form of directional cracks (cavity), like the surface texture of weathered limestone. The mounting of the plates to the overlap is carried out with the help of metal profiles, they can also be glued with special mastic directly to the rigid surface.

A peculiar texture and wide range of colors make a variety of premises in the interiors with the mass application of decorative acoustic slabs "Silakor" and gas-silicate plates.

Plates "Silakor" Made from a lightweight aerated concrete special structure with a density of 300 ... 350 kg / m 3. The facial surface of the plates can have a longitudinal slotted perforation, which gives it not only the best view, but also an increased ability to absorb noise. The sound absorption coefficient of Silakor plates in the frequency range from 200 to 4000 Hz is 0.3 - 0.8.

Plates from Gazilicata They have good operational and architectural and construction properties and represent a special group of sound-absorbing materials, including with a macroporous structure. The plates of 750x350x25 mm in size, 500 ... 600 kg / m 3 and a strength limit of 1,5 ... 2.0 MPa, sound absorption coefficient in the frequency range from 500 to 4000 Hz for microporous plates 0.2 ... 0.3, and for macroporous 0.6 ... 0.9. The technological process of production of plates consists of mixing raw materials - lime, sand and dye; Pouring the prepared solution in forms and autoclave processing, after which the products are milling and calibrated. A good appearance sufficient fire resistance and high sound-absorbing properties have acoustic perforated plates from dry plaster and gypsum perforated plates with a mineral wool soundder. They are widely used for interior decoration of walls and ceilings in cultural and household and public buildings.

Soundproofing of residential premises every year becomes more and more relevant. And every homeowner wants to choose the best sound insulation material, which covers noise from the outside. Although they are difficult to choose according to the principle of "bad-good", since many of them have a certain purpose and in one way or another performed the tasks.

So what is noise insulation? As a rule, noise and sound insulation is a complex multilayer design, which includes dense layers reflecting sound waves, and soft, absorbing foreign sounds.

In this regard, neither mineral wool nor membrane nor panel materials should be used as self-insulation.

At the same time, it is mistaken to assume that thermal insulators (cork, PPP, PPE, etc.) are able to fully fulfill the role of noise protection. They are not able to stop creating a barrier from the penetration of structural noise.

Even worse - if the sheets of polyurethane foam or foam places are placed on the wall, then such a design will strengthen the resonance of the incoming noise.

Overview of the best sound insulation materials

Rock Wool Acoustic Butts

In the first place you can put Rockvul Acoustic Batts, a group of companies, the eighth decades producing basaltolocon plates.

Stone wool compressed in the panel, found its use in both residential and industrial construction as a heat and sound insulator.

High cost caused by the need to purchase many add. Elements, the need to strictly follow the installation instructions.

Zipse panels

The panel system from the manufacturer "Acoustic Group" appeared at the very end of the last century. This is a multi-layered design whose composition varies depending on the purpose.

For ceiling and wall surfaces, puzzle plasterboard sheets are used as a base, for outdoor - gypsum-bones. They are complemented by fiberglass or basalt plates.

A large extent is prevented by the transfer of vibration and noise waves of vibrations from polymer and silicone. The degree of flammability G1 (weaklyor).

Benefits:
