What synthetic stones are used in soundproofing. Soundproofing materials. The cost of wall materials

If you are thinking about what kind of soundproofing material to choose for your apartment, then you are concerned about the issue of excessive noise in the premises of the dwelling. Just as often as the rest of the room, craftsmen today try to soundproof the ceiling. This at the same time allows you to achieve more impressive thermal insulation characteristics of the floor.

Varieties of sound absorbers for the ceiling

You can choose organic and inorganic materials for soundproofing work. Among the first are those that are based on polystyrene foam, chipboard or ecowool. The use of such noise absorbers implies ease of installation, affordable price and environmental safety.

Such soundproofing material as polystyrene is found today, perhaps more often than others, in insulation systems. It perfectly retains heat in the room, but is of interest to rodents.

From inorganic materials, stone wool can be distinguished, which is durable and safe for human health. The cost of this heater is very affordable, which acts as a positive feature. Stone wool is able to endure low and high temperatures ranging from -60 to +400 degrees. This indicates that this insulation copes well with high humidity conditions.

Work options

Soundproofing material can form the basis of various ceiling systems, for example, mineral wool can be installed in the hollow space of the suspension system. The canvases fit perfectly between the frame elements. But if you decide to use foam, then it is not recommended to use glue to fasten it, since the plates have a weight under which the material can move away from the base over time and cause even more noise. Glass wool can also be used, but it is worth remembering that this material must be well protected, since its elements can pose a danger to human health. In connection with this requirement, installation work using glass wool can be accompanied by more impressive labor costs. When using GKL as a finishing coating, special attention should be paid to joining the sheets, since sound penetrates perfectly through the cracks.

Soundproofing material, as a rule, is attached between the waterproofing, which is installed on rough overlap, and base ceiling.

Soundproofing materials for walls

If you decide to get rid of the noise in the room in a complex way, by sealing the walls as well, you can choose soundproofing systems, which are abbreviated as ZIPS. They perform several functions at once. By installing them, you will prepare the surface of the walls for subsequent finishing. This material has an insulating layer and GKL. Several sound insulators are assembled in the panel, namely: gypsum fiber and mineral wool, the latter is sometimes replaced by glass wool. The thickness and combination of internal components may be different. The weight is 18.5 kg, while the dimensions of one canvas are 1500x500 mm. The thickness can vary between 40-130 mm. The described soundproofing materials can be fastened by means of structural units.

Among the natural noise absorbers, one can single out ISOPLAAT boards, which are based on fibers softwood. The canvas size is 2700x1200 mm, while the thickness can be equivalent to 10-25 mm. The weight is very small and limited to 4 kg.

After installing such a material, you do not have to prepare the wall for finishing. It is recommended to mount the described boards with glue. They perfectly pass air, which does not create the effect of a thermos in the room.

Alternative options for soundproofing walls

Considering soundproofing materials for walls, one can single out ISOTEX panels, they are based on exclusively natural components of coniferous trees, they are distinguished by excellent flexibility and elasticity. If you choose just this way of dealing with noise, then you have to work with canvases whose dimensions are limited to 2700x580 mm. With a thickness of 12-25 mm, the insulation has a weight of 1.2 kg, which ensures ease of installation. Such soundproofing materials for an apartment look great and do not imply the need for wall decoration after their installation, since their outer side has a decor in the form of vinyl wallpaper or linen fabric. Installation consists in connecting the plates with a lock, and if necessary, cutting, you can use a construction knife.

EcoZvukoIzol panels have gained quite high popularity among private craftsmen, this is due to the fact that this material is environmentally friendly, as it is based on seven-layer cardboard and quartz sand. The canvases are somewhat heavier than those described above: their weight is 10.5 kg, dimensions - 1200x450 mm. But working with them is easy, despite the impressive weight. If necessary, adjust the panel to size, you can use a hacksaw, and at the time of fastening, you must also use an adhesive composition designed for drywall.

If you are looking for soundproofing materials for an apartment, then you can also consider wall panels, which are known as KRAFT. They have environmentally friendly wood-fiber elements, which are pasted over with wax paper on the outside, while corrugated cardboard on the inside. Their weight is 5.5 kg, which facilitates the installation process, but the dimensions are 2700x580 mm, which implies the need to enlist the help of another person before starting work. The canvas is quite simple to glue, and after the composition dries, you can begin the decorative finish.

The cost of wall materials

The listed soundproof materials for walls have a lot of advantages, sometimes it makes it difficult to make a choice. Perhaps the price will affect this. If we compare the above materials, then ZIPS costs 1300 rubles / m 2. But "EcoZvukoIzol" will cost less - 900 rubles / m 2. ISOTEX is even cheaper - within 600 rubles / m 2, the final cost in this case will depend on the type of decorative coating. KRAFT is the penultimate among the materials in the most affordable price category - 250 rubles / m 2. And the leader in the issue of democracy is ISOPLAAST, its price is 150 rubles / m 2.

Floor silencers

When choosing noise absorbers for the floor, the consumer, as a rule, pays attention to heat and sound insulating materials. The cork substrate, which fits under the top coat. This material is based on natural cork chips, which makes the sound insulator layer completely harmless. In addition to the fact that the cork will fight noise, it will last a long time, as it does not rot, mold cannot appear and develop in it. Cork does not attract rodents. The material is chemically inert, the life span is 40 years. It is able to reduce the noise level by about 12 decibels.

The listed characteristics of soundproof materials make consumers incline their choice in their direction. As an alternative solution, you can choose cork backing which contains elements of rubber. Synthetic rubber in tandem with cork does the job perfectly. The degree of sound absorption here is more impressive and is approximately 18-21 decibels. But you will have to pay more for such material.

The best cork soundproofing material is one that contains bitumen along with the main ingredient. The advantage of the substrate in this design is that it does not require additional waterproofing work, which cannot be said about the above. But here certain skills will be required, because bitumen stains hands and clothes.

Polyethylene foam for floor

Considering the soundproofing properties of materials, it is worth paying attention to polyethylene foam. It is also customary to lay it under the finish coating, for example, under the laminate. You can choose one of several varieties of this material. So, polyethylene with chemically bound molecules and cross-linked polyethylene have more impressive soundproofing characteristics compared to non-crosslinked polyethylene. Laying this material involves mandatory waterproofing, since when exposed to moisture, it can become moldy. It is advisable to lay it with a certain gap, since under mechanical loads the material loses up to 2/3 of its thickness, which causes a decrease in sound-absorbing properties.

"Shumanet" for the floor

Considering the types of sound-proofing materials, you will surely come across the Schumanet sound insulator. It is a composite substrate based on a multicomponent material. It contains three layers, the first of which is polyethylene, which protects against water, the second is polystyrene granules, while the third is a film that allows the penetration of moisture particles into polystyrene foam. After it is displayed around the perimeter of the room through the ventilation slots. The life of the material is about twenty years. It should be mounted by rolling, adhesive compositions are not used.

In addition to those listed, in order to combat noise, extruded polystyrene foam is used, which acts as the most dense variety of foam. It is practically like wood, does not absorb moisture at all, it is easy to work with it during the laying process, in addition, it is easy to cut it using a knife. It will last for about half a century. Considering soundproofing materials for walls or floors, you can choose it.

Speaking of the above, the most impressive degree of sound absorption is provided by the Shumanet-100 gaskets. At 3mm thick, they can reduce noise levels by as much as 23 decibels, while if you want even more impressive results, you can use 5mm material, the sound will be reduced by 27 decibels. The basis of the described gaskets is fiberglass, which has a special weave. If the manufacturer used staple weave, the noise would be reduced by 42 decibels. If you decide to lay these gaskets, then along the perimeter of the walls it is necessary to provide a gap, the width of which is 1 cm, which will be necessary to remove moisture.

Universal noise absorbers

When choosing soundproof materials for the ceiling, floor and walls, fiberboard can also be distinguished. It can be used in premises of any purpose. The basis of this material is wood fiber, as well as cement. In addition to the named ingredients, one can also use synthetic fibers. In order to form an acoustic surface, an acoustic fiberboard should be used. It is distinguished by an increased noise absorption coefficient, the level of which is 40 percent.

Stone wool also does an excellent job of absorbing noise, the sound absorption coefficient can be as high as 99 percent. It copes well with changes in temperature and humidity, so it can be used in almost any room.

Impact noise suppression methods

Soundproof materials for the walls of the apartment, which were described above, can cope with airborne noise. But if there is a need to eliminate impact noise, then you can use a floating floor system, which is not rigidly connected to the rough floor. An insulating layer is used as the basis of this system, it can be the one described above stone wool. If the sound insulation of all surfaces of the room was not enough, then special attention should be paid to doors and windows. In this case, PVC profiles come to the rescue, which have very good noise-absorbing qualities. As a rule, an inert gas is located between two windows in the hollow space. The most common of these is argon.

The range of modern noise absorbers is large, but it is worth remembering that they should be used in a complex way, in addition, sometimes the quality of sound absorption depends on the correct installation of the material. Only if the installation technology is observed, it will be possible to achieve a positive result, and your neighbors will not interfere with you, just like you, which is very important, especially in apartment buildings.

Today more and more topical issue is the soundproofing of the premises. This issue is especially acute in large cities, where there are a huge number of different sources of noise, moreover, it is growing every day. At the same time, the demand for high-quality soundproofing materials is increasing.

In today's bustling world, the opportunity to be in peace and quiet is a luxury that not everyone can afford. They will almost always be able to protect from sounds from the street quality windows(how to choose them, we wrote in previous articles), but getting rid of the invisible "presence" of neighbors is not an easy task. Nightly cries of children, loud birthday celebrations, singing in the shower and much more can become more than just sources of irritation. If it is impossible to have a good rest in your own home, even health problems can arise - chronic fatigue and neuroses. In addition, it is impossible to fully enjoy beautiful loud music or a movie in a home theater without fear of disturbing anyone.

There is only one way out - to carry out high-quality sound insulation, and it is quite possible to do it with your own hands. Today, a wide range of these products is presented on the market, so it can be very difficult for a modern consumer to independently understand all the nuances and technical and operational characteristics of this category of goods. How to choose soundproof materials, which are better and more effective in a particular situation, as well as what comparative characteristics they have, this material will help to understand.

They are chosen to solve specific technological problems - depending on the type of noise, the functional purpose of buildings and operational requirements. In conditions apartment buildings partitions and bearing walls- this is just a conditional barrier to the propagation of sound waves. However, in order to get complete independence from noise, not to disturb the neighbors, the problem can be solved very easily - you need to carry out high-quality sound insulation.

First you need to decide on the type of noise that affects. They are divided into three general groups:

• Airborne noise - they travel through the air. If an obstacle in the form of walls, partitions or ceilings is encountered on the path of a sound wave, then it does not go out, but causes oscillations in them. They are transmitted to air particles in neighboring rooms, so we hear sounds. Examples of such noise can be a receiver working loudly, neighbors talking, a baby crying, and so on. High-quality soundproofing material is able to dampen vibrations, helping to eliminate the problem;
• Impact noise - occurs during mechanical impacts on structures. This can be rearranging furniture, falling objects on the floor, hitting, and more. Then soundproofing must be subjected to floors and ceilings;
• Structural noise - in this case, sounds propagate through the structures of the building. It is most difficult to get rid of such noises, only complete soundproofing of the entire apartment will help here.

There is also complete and local soundproofing. The latter method involves noise isolation of especially weak points.

Overview of soundproofing materials

Sound waves, which are produced both by sources inside the house and outside it, propagate to all structures fixed to each other. As a result, sound that occurs in one place is often heard in another, carried throughout the building. You can protect yourself from it not only in a closed room provided with high-quality sound insulation, but also in a properly designed open space.

The main parameters that determine the soundproofing properties of materials are Ib - the index of insulation from airborne noise, as well as Iy - the index of the reduced level of impact noise under the ceiling. In European countries, another designation of the parameters Ib and Iy is adopted - Rw and Ln, w, respectively. Indices Iv and Iy can be recalculated in Rw and Ln, w according to the formulas: Rw - Iv + 2 (dB), Ln, w - Iy - 7 (dB).

In the modern construction industry, the most popular and common are the following types of soundproof materials, according to the generally accepted classification:

• Mineral wool;
• Styrofoam;
• Viscoelastic membranes;
• Foamed polymers;
• Sandwich panels;
• Natural cork;
• Cellulose materials (ecowool);
• Foam glass;
• Rubber sound insulators;
• Soundproof underlays.

Each of them is worth a detailed consideration, as it has a number of advantages and limitations.

Mineral wool One of the most common materials today is mineral wool. It perfectly absorbs sounds - moreover, both shock and air origin. These characteristics allow it to remain the most popular material for these purposes. For work, special plates or mats are used, made on the basis of acoustic mineral wool.

Such products are distinguished by high sound insulation rates, which are achieved due to the special arrangement of the fibers. The structure creates open air cavities that perfectly dampen sound vibrations. As a result, mineral wool is characterized by excellent sound insulation properties, while being characterized by low dynamic stiffness. A very important indicator of the effectiveness of sound insulation is the sound absorption coefficient ap, which depends on whether the wool is glued to the surface or separated from it by air space, whether there is facing materials. 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.

Expanded polystyrene is the second most popular material for these purposes. However, it is only capable of absorbing percussive sounds, and in order for it to obtain optimal sound insulation properties, it must be slightly pressed down 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 provide insulation for ceilings - floors and ceilings. If laid on the floor, it can be perfectly compressed by pouring a concrete screed 3-6 cm thick.

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

It is necessary to lay the material on a flat base, close to each other. The seams are displaced by half the length of the slab, and the seams on the edge are usually made from the same material. Before pouring the screed, a separating layer of film material or roofing felt is laid on the expanded polystyrene base. For soundproofing, plates of small thickness - up to 4 cm are perfect.

membranes. With regard to viscoelastic membranes, they also seem to be a very convenient material for soundproofing. They are used, as a rule, to increase the protection of frame walls from extraneous sounds. However, viscoelastic membranes are also manufactured for:

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

They are high-density synthetic soundproofing materials made of polymers, without the use of bituminous resins and rubber. Differ in high rates of elasticity, flexibility, durability, durability and fire resistance. They are also used as vibration-damping middle layers to increase the sound insulation of frame walls and prevent the occurrence of resonant effects. A viscoelastic membrane is glued onto gypsum boards from the inside of the supporting frame. The use of such materials makes it possible to increase protection against extraneous sounds by 25-32 dB.

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

Panels. V Lately Sandwich panels began to gain great popularity in the market of soundproof materials. They can be completely different in length and composition; they are used, as a rule, for soundproofing single-layer partitions. Today, more and more often, to create additional protection of single-layer partitions (for example, brick walls) from sound waves, they began to use ready-made soundproofing systems. These are sandwich panels of different thicknesses, which consist of a combination of materials of different densities and structural characteristics. The advantages of their use include the absence of the need to install a metal frame - they are attached directly to the walls.

One of the most popular options is a combination of a dense layer (gypsum fiber sheet) and a light layer (mineral wool) - the thickness and structure of the materials may vary. They are mounted using vibration-isolating materials through special units made by the manufacturer. The thickness of such panels can be from 40 to 150 mm, and is selected based on the thickness of the supporting partition. The increase in the sound insulation index depends on the density and can range 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 dowels (possibly also to the crate), and also laid on the floor, replacing floating floor systems and cement screeds. Each of the carcass layers has its own indicators of multiple reflection and scattering of sound waves, which makes it possible to achieve a reduction in airborne noise of up to 37 dB with a material thickness of 10 mm.

Cork. Natural cork materials have been used for a long time to create high-quality sound insulation of premises, however, thanks to the development modern technologies, the sound-absorbing qualities of cork flooring are constantly improving. And, if previously a technical cork with a grain size of 5-8 mm was used, today it is made with better sound insulation indicators, which are provided by smaller sizes - 1-3 mm, but the air voids here are 3 times larger.

Ecowool. Cellulose insulation based on ecowool is also excellently used as a soundproofing material - at the same time, they can be used for different types of noise and different rooms. The material is obtained in the process of processing secondary raw materials - waste paper. It consists of 80% recycled cellulose, 15% antiseptics, and 5% fire retardant. It is used not only for insulation, but also for suppression of airborne noise:

• on floors that separate unused attics;
• filling frame walls and partitions.

The soundproofing characteristics of ecowool are due to the structural features of the material - there are a large number of fibers separated by air space. It is blown with the help of special equipment and, depending on the place of application, is laid in layers of different densities.

Foam glass. The material has high technical and operational characteristics - high strength, resistance to aggressive chemical compounds, fire safety, ease of processing, thanks to which the material has gained immense popularity in European countries. Foam glass plates are very easy to cut - they can be mounted both outside (lay as a middle layer of an insulating "pie") and indoors. In addition, they can serve for the construction of light internal partitions. A 10 cm thick slab provides protection against sound insulation up to 30 dB.

Rubber. Rubber-based soundproofing materials are excellent for absorbing impact types of noise. Very often used for industrial premises, however residential buildings can also be isolated with their help. They are made from recycled rubber (sometimes with the addition of cork).

Very often they are used as sound insulation under household appliances, the operation of which is accompanied by the appearance of vibration waves (washing and dishwashers). They can also be used directly under floor coverings, under floating screed or concrete slabs, as well as under hard floor elements on a wooden base.

Manufacturers offer materials for various types of flooring: parquet, parquet boards, laminates, carpets, linoleums and even ceramic tiles. During installation, it is necessary to control that there are no gaps left - all layers must be tightly fixed to each other, otherwise acoustic bridges will appear on the seams, which worsen the design parameters. Allows you to reduce impact noise up to 15-33 dB.

Substrates. The peculiarity of underlays for flooring is that they suppress shock, but not airborne noise. However, they will be indispensable for laying under laminate and parquet, especially if the construction of these floor coverings does not include a layer of sound absorber. Helps to prevent the appearance of dull noises, which are accompanied by walking on the floor, and which are heard in the rooms below. Substrates for sound insulation can be presented in the form of:

• Elastic mats made of 4 mm thick polyethylene foam, which level the unevenness of the bases, prevent the spread of impact noise and the occurrence of sound bridges;
• Fibreboard made from pressed wood fibres. They are light and porous, they are an even and elastic basis for floor coverings;
• Cork mats that are compressible and elastic, do not absorb water and do not age;
• Corrugated cardboard, which perfectly suppresses noise and does not let water vapor through, while not shrinking;
• Tuplex mats, which are approximately 3 mm thick, are a two-layer polyethylene film heterogeneous composition, separated by a layer of polystyrene foam granules, which are recessed in glue. Great for laying under wooden or panel floors. They are distinguished by high noise suppression capabilities - 17 dB. This material has moisture-proof properties, so when laying it, the use of a vapor barrier is not required.
• Polyurethane foam mats, depending on the type of which can be used for laying under elastic coatings on glue, linoleum, as well as under glued and free-standing rubber or carpet materials. They can also be laid on load-bearing floor structures, on seamless, puttied plank floors, PVC coatings, on stone and ceramic tile floors, varnished parquet floors. The thickness of the mats is 2.5 mm, and the noise suppression capabilities are 17-19 dB. Polyurethane foam mats improve sound insulation by 23 dB.

Mountings on which sound insulation is installed deserve special attention. As a rule, for these purposes it is necessary to mount plasterboard frame structures on walls and ceilings. However, the presence of a rigid fixation between the protected surfaces and the metal frame in the form of standard metal hangers and brackets leads to the fact that even with the use of gaskets, the noise is transmitted to the cladding and then to the premises.

Soundproofing materials: table

To solve this problem, it is necessary to use special soundproof fasteners that are strong enough, but at the same time plastic, and also have soundproofing characteristics in a wide frequency range. Fasteners have a large number of varieties, they differ in scope, design features and the type of elastic element used.

However, sound insulation can be not only continuous - there is also local insulation. In addition, very often there is protection not from external sound waves, but vice versa - it is necessary to protect neighboring rooms from sounds, in such cases acoustic insulation is performed.

Local soundproofing

Since childhood, everyone has known "spy" ways to listen to neighbors through sockets. Typically, these elements are different apartments they are made through, and the builders not only do not equip them with soundproofing, but do not even put up partitions. In such cases, you can simply call an electrician or fix the problem yourself, following the rules and safety precautions when working with electricity.

To do this, it is necessary to de-energize the socket, remove it and then remove the mounting box. The hole must be sealed with cement or mounting putty, after drying which 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 by simply tapping the wall, although in this case it is best to use the services of professionals, since there are a large number of electrical cables.

Another source of local noise can be plumbing, heating and sewage risers. Their soundproofing should be carried out at the construction stage - sleeves of a larger size than required are inserted into the ceilings, and the space between them is filled with non-combustible soundproofing material. From above it is sealed with a special plastic sealant (how to choose it, read the material about sealants). However, in practice, the situation is completely opposite - the pipes are simply passed through the floors, and the gaps are sealed with simple cement, which not only conducts sound waves perfectly, but cracks and collapses over time.

To eliminate this drawback, it is necessary to clear the old cement as deep as possible, wrap the pipe with soundproofing material, cement the dismantled section of the floor, and seal the joints themselves.

The last point of local sound insulation is the elimination of deep cracks between partitions and walls. To create barriers to sound waves, you can fill the joints with gypsum plaster, cement, or plastic sealant.

Acoustic isolation

Most modern premises providing a comfortable acoustic environment is one of the main functional requirements (for example, for cinemas, concert halls, multipurpose and conference halls, office premises and others).

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

One of the main criteria that characterize the acoustic qualities of rooms is the reverberation index (RT60). At their high values, the perception of sounds is distorted, speech intelligibility indicators decrease, at very small values, the effects of “lifelessness” of the premises, “dryness” of the reproduced sound effects appear. In most cases, modern acoustic materials and constructions make it possible to ensure optimal reverberation rates (or adjust them), which provide high sound absorption rates in rooms.

To ensure optimal sound absorption, the greatest attention should be paid to the ceiling space. Therefore, "acoustic" ceilings have been made for quite a long time, which absorb sounds. In large buildings, where the ceiling space alone is not enough to improve acoustics, it is also recommended to use special sound-absorbing wall panels.

The technical and operational characteristics of ceiling and wall sound-absorbing panels include: acoustic and hygienic parameters, moisture resistance, fire-technical parameters, impact resistance, lighting characteristics and duration of operation. To date, there are a large number of materials that are suitable for solving not one technological problem, but a whole range of requirements, for example, to provide the necessary acoustic parameters in rooms with high humidity- in the pools. Moreover, these systems also perform 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 on which frequency range needs to be corrected. By absorbing characteristics, they can be divided into: medium and high-frequency absorbers, as well as low-frequency absorbers;

The first type includes:

• porous boards;
• fibrous materials, which can be made in the form of plates of mineral or glass wool, artificial or wood fibers. The front part can be treated with special porous coloring compositions and covered with cloth

Low frequency absorbing materials can be presented as thin panels with various perforations, which can be made from gypsum boards, MDF, wood and other materials. Low-frequency absorbers include, in addition, resonant structures made of porous-fibrous materials, with perforated fabric screens and air gaps.

The modern market of soundproofing materials is represented by a wide range of products, among which everyone can choose the one they need - in full compliance with the technical and operational requirements that impose installation features. In this material, all materials were described in detail, as well as the features of their application.

As the quality of housing improves, when the issue of the number of square meters has ceased to be the only determining factor, the problem of soundproofing residential premises is becoming increasingly relevant. However, due to the fact that this question is quite specific, i.e. in the theory of acoustics there are a lot of implicit features and "illogical" conclusions from the point of view of common sense, a large number of myths and misconceptions have arisen and established themselves in this area.

This leads to the fact that a large number of people have formed a stable stereotype about what materials, if necessary, can solve all the problems of insufficient sound insulation. However, the practical use of such materials at best will leave the situation without visible changes, at worst - will lead to an increase in noise in the room. As a first example:

The myth of the soundproofing properties of cork

Almost everyone believes that cork is a good sound insulator. Statements of this kind can be found on many building forums. And the "technology" of application is "developed" to the smallest detail. If you hear a neighbor behind the wall, you need to paste a cork over the wall that is common with your neighbor, if the noise comes from the ceiling, then the ceiling. And the resulting acoustic effect is amazing ... with its absence! But what's the matter? After all, the seller showed acoustic test data, where the effect of sound insulation was indicated, and not a very small effect - about 20 dB! Is it cheating?!

Not really. The numbers are true. But the fact is that such figures were obtained not for "sound insulation in general", but only for the so-called impact sound insulation. Moreover, indicated values only valid when the cork is laid under concrete screed or a parquet board from a neighbor upstairs. Then you really hear the neighbor's steps quieter by 20 dB compared to how if the neighbor did not have this pad under his feet. But for music or the sound of the neighbor's voice, as well as for all other cases of using cork in other versions, these "sound insulation" figures, unfortunately, have nothing to do. The effect is not just barely noticeable, it is zero! Of course, cork is environmentally friendly and warm material, but it is not worth attributing to it all possible soundproof properties.

All of the above also applies to foam, polyethylene foam (PPE), polyurethane foam and other similar materials, which have different trademarks starting with "foam-" and ending with "-fol", "-fom" and "-lon". Even with an increase in the thickness of these materials up to 50 mm, their soundproofing properties (with the exception of impact noise insulation) leave much to be desired.

Another misconception closely related to the first. Let's denote it as:

The myth of thin soundproofing

The basis for this misconception is the struggle to improve the acoustic comfort of the room, along with the desire to preserve the original square meters. It is quite understandable the desire to maintain the height of the ceiling and the area of ​​​​the room, moreover, for typical apartments with a small footage and a low ceiling. According to statistical observations, the vast majority of people are ready to sacrifice "for sound insulation" an increase in the thickness of the wall and ceiling no more than 10 - 20 mm. In addition, there is a requirement to obtain a rigid front surface ready for painting or wallpapering.

Here, all the same materials come to the rescue: cork, PPE, polyurethane foam up to 10 mm thick. Thermal soundproofing is added to them in a separate line. But for this case, these materials are sewn up with a layer of drywall, which acts as a rigid wall, ready for finishing.

Since the acoustic properties of cork and PPE for soundproofing walls and ceilings were discussed above, we will focus on thermal soundproofing.

Thermozvukoizol (TZI) is a rolled material, where Lutrasil polymeric material is used as a shell (like a duvet cover), and super-thin fiberglass fibers are used as stuffing (blanket). The thickness of such material fluctuates around 5-8 mm. I do not presume to discuss the thermal insulation qualities of VBI, but as for sound insulation:

Firstly, TZI is not soundproofing, but sound-absorbing material. Thus, we cannot talk about his own sound insulation. We can only talk about the sound insulation of the structure in which it is used as a filler.

Secondly, the sound insulation of such a design largely depends on the thickness of the sound-absorbing material located inside. The thickness of the VBI, at which this material will be effective in a soundproof structure, should be at least 40 - 50 mm. And this is 5 - 7 layers. With a layer thickness of 8 mm, the acoustic effect of this material is VERY SMALL. As, however, in any other materials the same thickness. Nothing can be done - the law of acoustics!

ZIPS panels can be recommended as a really effective material for additional soundproofing of walls and ceilings. For example, ZIPS-Vector panels with a structure thickness of 53 mm increase sound insulation by 9-11 dB, and the latest ZIPS-III-Ultra with the same thickness - by 11-13 dB. The panels are patented and this moment have no analogues in the world.

Thus, with a total thickness of the structure of additional sound insulation of 20 - 30 mm (including a layer of drywall), one should not expect any increase in sound insulation that is noticeable to the ear.

In addition to these, perhaps the most common misconceptions, there are others, less known, but no less significant. Therefore, in matters of ensuring the required sound insulation of premises, it is best to immediately contact specialists. Sometimes a single glance is enough for a professional acoustician to immediately assess the ineffectiveness of the proposed measures or the materials used. But the most unpleasant thing is to spend time, effort and money, and not feel the results of your work.

In order for the sound to be reflected from the wall of the room and not be heard outside it, a technique such as soundproofing is used. To prevent the penetration of noise outside the room, soundproof insulation for soundproofing plates helps. Usually this characteristic directly depends on the thickness of the material - the wider the soundproof barrier, the less likely it is to hear sound. Also, the method of sound insulation is used in the construction of buildings and is measured in Dicibels. Normal indicators of soundproofing characteristics are from 52 to 60 dB. Soundproofing materials reflecting sound, include brick, drywall, concrete and others.

Sound absorption

The main purpose of the above characteristic is to prevent sound from bouncing off the wall. According to their structure, soundproofing boards consist of fibers or cells. The noise absorption coefficient varies from 0 to 1. If it is zero, the sound is reflected into the room, and if it is one, the sound is completely absorbed by the material. Materials corresponding to a number of 0.5 and above have a noise absorption characteristic. For a comfortable state, a person should be in a room with a noise of 25 dB, since at a lower coefficient he will feel oppressive silence, and at a higher one he will complain about noise and headaches. A person calmly endures noise up to 60 dB, but a higher volume can adversely affect health. In order to protect yourself from noise, you can use soundproof heaters, depending on what your goal is.

Such material has its own degree of rigidity:

solid material - created with mineral granular water. The composition of this kind of raw material includes vermiculite, perlite and pumice. The absorption coefficient is optimal 0.5 dB at a mass of 300 kg/m3;

semi-rigid material - mineral wool slabs, having a structure in the form of cells. Sound absorption coefficient from 0.5 to 0.7 dB with a mass of 130 kg/m3;

soft material - created on the basis of cotton wool or felt. Sound absorption coefficient from 0.5 to 0.95 at a weight of 70 kg/m3.

In the construction of private houses, soundproofing devices of the last specified parameter are usually used. You should also choose soundproofing with the necessary properties for the nature of the noise emitted.

Types of noise emitted:

air, emitted from televisions, receivers, animals;

percussion, emitted when walking, repairing, drilling;

structural, appearing in the presence of connected load-bearing structures of the building.

To cope with impact noise, soundproofing is usually used. soft materials with cell structure. Sound-proof fibrous materials are used against air, and special cushioning materials protecting the joints of structures are used against structural.

Analyzing the indicators of table No. 1, we note that the basis contains mineral fiber, they are characterized by similar sound absorption coefficients, the difference is within 10%. A product made of a material based on perforated gypsum is somewhat inferior in terms of sound-absorbing properties to mineral fiber boards. Gypsum soundproofing insulation can help increase the effect with an additional insulating layer. During construction public buildings and finishing, strict standards are applied, which are designed to ensure the safety of people in the room. Fire and environmental safety requirements create a tight framework for soundproofing panels, the observance of which is strictly regulated. In addition, the materials used for finishing should be durable, easy to use, have moisture-resistant qualities and have an attractive appearance.

Continuation of table number 2

Soundproofing materials in this table #2 reflect the difference in performance. For example, foamed acoustic material based on melamine resin Illbruck (Germany) has a low density, as well as a rather low resistance to temperature extremes. This indicates the need to take into account that the scope of such materials is very limited. Soundproofing materials and their density produced by Ecophon, Parafon and Rockfon are about the same level. The similarity of this parameter is provided by a similar insulating structure of this material. Soundproof boards of these brands have a density that is much higher than that of foamed materials, and in relation to the density of gypsum panels (900-1200 kg/m3) it is lower. At the same time, products for sound insulation made of basalt fiber are distinguished by the properties of fire safety, moisture resistance, environmental friendliness, thermal insulation and durability. This is quite a big advantage, allowing you to use them during installation. suspended ceilings and as acoustic soundproofing wall panels for all types of premises: from apartments and offices to cinemas and recording studios.

Soundproofing products in the premises of cinemas perform the main task - this is the preservation of the sound mode throughout the area. Materials should not allow this sound to spread outside of it.

The implementation of such sound insulation is carried out immediately by a set of actions. For example, for such work, several types of materials are used at once, which are engaged in sound absorption. Such materials sheathe not only walls and ceilings, but also the floor.

Such coatings are called carpet. It is necessary when decorating rooms, because it has a very beautiful and even surface with a short pile. This makes carpet very similar to carpet or carpet.

Also for owners of cinemas, soundproof products are provided in a huge selection of colors. And there are not only standard colors, but also various shades that will suit almost any interior and hall design. Owners can choose not only the quality that suits them, but also choose the color, the ratio of which to the upholstery of the furniture will be ideal.

Soundproofing material and its technological properties?

In the cinema, you need to create using additional materials unprecedented acoustic perfect sound insulation. This is necessary so that all vibration, all hum and all sounds must remain in one isolated room. Carpet, in turn, perfectly copes with the task entrusted to him. It not only easily reduces sound transmission, but also does not violate acoustic performance at all. This material is very easy to install as it is very malleable and very easy to cut and stretch. Without problems, it can also be fixed on the ceilings, which forms a perfectly smooth surface.

The only condition for the installation of the carpet is the temperature of the room. All soundproofing should take place in a room whose temperature should not fall below 16 degrees. Otherwise, the carpet completely stops stretching, which does not allow the webs to be joined on uneven areas.

In such cases, the use makes it possible to minimize noise and provide comfortable acoustic conditions for the rooms that are adjacent to the cinema hall.

Do not forget that the soundproofing of the hall makes it possible to enjoy the film, completely immersing in its atmosphere, without being distracted by a rather loud noise from the corridor or the neighboring cinema hall.

In the modern world, for the full implementation of the sound insulation process, materials are used that sufficiently have sound-reflecting or sound-absorbing properties.

Priority areas for soundproofing a cinema or bowling hall.

1. The most important task is to isolate the sounds of a cinema or bowling alley from nearby rooms. Therefore, soundproofing is necessary not only for walls, but also for ceilings and floors. This will prevent further propagation of the sound. For a cinema, soundproofing of all rooms in which a movie is being watched is mandatory.
2. An important task is to provide acoustic comfort directly in the hall where a movie is being watched or a bowling game is being played. This requires sound insulation as well as technical equipment: air conditioners, fans, refrigerators, etc.
3. Do not forget that soundproofing should not interfere with the comfortable viewing of movies. The speech of the actors should be easily receptive and audible. In a movie theater, the sound needs to radiate evenly and rationally through the auditorium in order to reach all the rows at the same time. In the bowling alley, such subtleties are not provided.

7 8 9 10

With the development of modern technologies, the frequency range of sound sources has expanded significantly. Residents of panel and block high-rise buildings especially suffer from this. Contrary to popular myths, traditional insulation such as mineral wool, foam or cork does not improve sound insulation. To fully protect your apartment from noise penetration, you should look for a comprehensive solution and it is best to invite an acoustic engineer for this. This is recommended in case of severe acoustic discomfort. If it is required to reduce noise pollution by 5–10 dB, one can resort to special noise-insulating materials, applying them in the design frame partitions and wall cladding. This rating contains a list of the most effective of them and is based on expert opinions and user reviews.

The actual characteristics of sound insulation may differ from those declared by the manufacturer, since they largely depend on the degree of tightness of the fences, their total mass and 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 next to a noisy engineering equipment, the neighboring subwoofer regularly rumbles 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 wasting time and money, we suggest evaluating the pros and cons of different materials.

Material
Construction drywall	Affordability Lightweight finished partition Versatility Tangible result when arranging a double partition	‒ complexity of installation ‒ significant loss of area ‒ minimum sound insulation of a single frame without sound absorber
Soundproof drywall	Highest sound insulation properties due to increased density and reduced rigidity Can be used for soundproofing music studios and home theaters	- much more expensive than usual ‒ when fastening the GK-cladding, it requires installation using special fasteners - in the future, it is undesirable to mount heavy interior elements on the cladding
Sandwich panels	Multilayer structure Ease of installation Sufficiently high sound insulation, subject to tightness of the fence	‒ thick panels - high price installation work ‒ a noticeable reduction in the usable space of the apartment
Acoustic mineral wool	Suitable for soundproofing walls, floors and ceilings, including stretch ceilings Produced from high quality raw materials Successfully solves the problem of airborne and impact sound transmission Has high thermal performance	‒ low hydrophobic properties ‒ lack of specialists in the labor market for the installation of acoustic materials - the high cost of arranging a soundproofing system
Roll materials	Democratic value Possibility of self-assembly Convenient format for wall decoration Space saving	‒ minimal acoustic effect when using one layer - the need for plasterboard sheathing for finishing walls

Conclusions: there are no materials that provide complete sound insulation. In order to attenuate the sound as much as possible when it penetrates through the wall, it is necessary to build a soundproof structure of the “mass-elasticity-mass” type.

5 Soundguard Ecozvukoizol

The thinnest sound insulation
Country Russia
Average price: 920 rubles.
Rating (2019): 4.7

The thinnest sound insulation in our review was the domestic panel Soundguard Ekozvukoizol. Its thickness is only 13 mm. It is not difficult to calculate the number of panels per room, since the dimensions of the sheet are quite accurate (1200x800 mm). The manufacturer managed to achieve the soundproofing effect through the use of quartz filler. Noise-insulating panels greatly reduce the impact of sound and shock waves in a wide frequency range. This was achieved by increasing the weight of the sheet, the use of a multilayer layer. It contains elastic, integrated and vibration damping layers, as well as free filler particles.

The panel is mounted in the same way as plasterboard sheets, it can be used for soundproofing both walls and ceilings. Soundproofing is allowed only interior spaces with low humidity. You can cut the panels with a hacksaw, circular saw, grinder or electric jigsaw. Sheets are mounted both on an independent frame and directly to the wall surface. In the latter case, the surface must first be leveled with fiberboard or Soundguard Roll.

Most of the owners of apartments and houses in the reviews positively characterize Soundguard Ekozvukoizol soundproof panels. They do not steal the area of ​​​​rooms, they are easy to use. Some users are not happy with the high price and heavy weight of the sheets.

Rating (2019): 4.9

Acoustic triplex Soundline-dB has unique soundproofing properties. It is made on the principle of an automobile windshield. A special sealant is applied between two moisture-resistant weighted drywall sheets (8 mm). Due to the elasticity of the layer, the sound flow is reduced due to the gradual absorption of waves. In other words, each drywall sheet oscillates on its own. The total sound insulation is much higher than that of the same two drywall sheets without an acoustic layer.

Testing of the material showed that it has the lowest flammability, toxicity, combustibility 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 sound insulation, it should be noted ease of installation, a high degree of sound insulation (up to 69 dB), the preservation of its properties for up to 25 years, and low cost.

Installation of a triplex is in many ways similar to the creation drywall constructions. It is only necessary to select the appropriate self-tapping screws for the thickness of the sound insulation (17.5 mm). You should also make allowances for the large weight of the three-layer canvas.

The owners of houses and apartments in the reviews praise the soundproof qualities of the Soundline-dB triplex. It is easy to install, effective in combating noise, has a small thickness. Among the shortcomings can be noted a lot of weight and bulkiness.
