Soundproofing properties of materials table. Modern soundproofing materials for houses and apartments
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 soft materials with a cell structure are usually used. 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 the construction of public buildings and decoration, 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 them to be used in the installation of 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, it is necessary to create an unprecedented acoustic ideal sound insulation with the help of additional materials. 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.
- 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.
- 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.
- 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.
The ability of a material to protect from noise will tell you the index of sound insulation – Rw.
Impact noise, as the name implies, occurs when shocks appear, for example, when hammering nails or moving furniture. Finally, structural noise is the sounds of nature penetrating through the structural elements of the house.
The key characteristics of a soundproofing material are the actual sound insulation and sound absorption. It must reflect or absorb sound, preventing it from entering the room.
From the point of view of acoustic engineers, there are no soundproofing materials in nature - only special designs in which structure is extremely important. Often, builders use multilayer systems in which sheets of dense drywall alternate with layers of porous materials, such as mineral wool. But, unfortunately, they reduce living space and are quite expensive.
The secret of effective sound-proofing is a combination of special design and material.
Overview of popular soundproofing materials
Modern technologies allow the use of simpler and more profitable materials that provide isolation from external and internal noise. So, ZIPS sandwich panels have proven themselves well on the market. They are a combination of dense gypsum fiber and soft glass wool layers. Their thickness varies from 40 to 130 mm, and Rw is 10 dB.A thinner material is ISOPLAAT heat and sound insulation boards. Their thickness does not exceed 25 mm, while their sound insulation index is twice as high as that of ZIPS - 23 dB. In addition, ISOPLAAT is made from environmentally friendly fibers of coniferous trees. The plates are mounted with glue and "breathe" well.
The thinnest panels are EcoZvukoIzol and Kraft - 12 mm and 13 mm, respectively. The former are made of a seven-layer cardboard profile with the addition of quartz sand, the latter are made of fibreboard. Both those and others are easily attached with ordinary glue. The sound insulation index of both is approximately equal to 23 dB.
Finally, it is worth warning about the most common misconceptions. There is an opinion that materials such as cork, PPE, polyurethane foam do a good job of soundproofing and at the same time, thanks to their small thickness, they help to save square meters. In fact, this is not entirely true - they only absorb impact noise, but do not at all isolate from the air.
Soundproofing is measured in decibels, a term used when it comes to reducing the volume of outgoing/incoming noise.
Sound absorption is evaluated by calculating the sound absorption coefficient and is measured from 0 to 1 (the closer to 1, the better). Sound-absorbing materials absorb the sound inside the room and dampen it, as a result, the echo disappears.
If you need to get rid of the noise of your neighbors, you need soundproofing materials. If you need the absence of echo in the room - sound-absorbing.
How to reduce the noise of neighbors from above / below / behind the wall? Can I save them from my noise?
Soundproofing the ceiling is obviously a losing option. A maximum reduction of 3 to 9 dB can be achieved. Try to negotiate with your neighbors and make them soundproof the floor, then you will achieve a reduction of up to 25-30 dB!
The sound insulation of a wall depends on the type of wall. They are either being built or already existing (between rooms and apartments). For erected walls, immediately make double, independent frames. The thicker and more multi-layered the wall, the higher the chance of achieving noise reduction by 50-60 dB in the apartment.
For existing walls - either make a frame filled with soundproof materials, but get ready for it to “eat” 10 cm of space. Or, if space is tight, attach soundproofing panels or roll material directly to the wall.
To soundproof the floor, place materials such as TOPSILENT DUO or FONOSTOP BAR under the screed. If it is not possible to raise the floor under the screed by 10 cm, then place soundproofing materials under the floor covering. Please note that the noise in this case will decrease by no more than 10-15 dB.
Try not to let the screed and flooring come into contact with the walls of the premises. The "floating" design provides the best soundproofing properties. Conversely, if the soundproof layer climbs a couple of centimeters onto the walls, this will additionally dampen the sound waves.
We made repairs, didn’t think about soundproofing and now we hear the noise of neighbors, how to fix it?
Unfortunately, you will have to make changes to the repairs already made.
If floor soundproofing is required, remove the laminate (or other finish) and place the FONOSTOP DUO soundproofing membrane under it.
If the walls, then, as mentioned above, the coating must be removed, a frame made and a material like TOPSILENT BITEX glued. Likewise for the ceiling.
What materials to use for soundproofing an apartment? How many do you need? How to calculate the required amount?
Soundproofing an apartment requires an integrated approach. A structure is being assembled, a “sandwich” of several materials. The thickness of a quality construction is about 7-10 centimeters.
To calculate the required quantity, send the dimensions of the room - length, width and height, the manager will make the calculation and tell you what materials will be needed.
What materials do you need for a recording studio?
For a recording studio, both types of materials are important and necessary - soundproof and sound-absorbing. First of all, high-quality sound in the studio is achieved through the use of sound-absorbing, acoustic panels made of melamine foam or open-cell polyurethane. The cellular structure of the material "quenches" sound vibrations. We recommend using thick panels up to 100 mm, this will ensure sound absorption in a wide frequency range. In addition, install "bass traps" up to 200-230 mm thick.
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 is the best soundproofing?
The best material is the one that solves the problem. The same soundproof materials manifest themselves differently depending on the volume, type of walls, ceiling of the room. We recommend that you consult with a specialist before starting repairs.
How is soundproofing and sound-absorbing materials installed?
The easiest way is to attach sound-absorbing acoustic panels. Take any type of glue and attach where you need. The material is light and easily adheres to the surface.
For the installation of soundproofing materials, specially designed adhesives are used - OTTOCOLL P270 (for floors) and FONOCOLL (for walls and ceilings).
Do you deliver materials? Is there a self pickup?
Yes, we deliver. Choose a convenient delivery method: pickup from a warehouse in Lyubertsy, delivery by van within the Moscow Ring Road and the Moscow region (up to 100 km) or a transport company if you are far from Moscow.
Where to see prices?
Prices for soundproofing and sound-absorbing materials can be found in the "Price Lists" section.
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, using them in the construction of 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 noisy engineering equipment, a neighbor's 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.

Rating (2019): 4.3
"Ehokor" are acoustic panels for soundproofing apartments, private houses, public buildings with varying degrees of noise pollution. Their production is carried out by the Alliance company, using a unique raw material - foamed melamine of the German brand Busf. Outwardly, melamine is very similar to foam rubber, but, unlike it, it is absolutely non-combustible, has an open-cell structure and low thermal conductivity. This combination of properties makes the material attractive for solving a number of construction tasks, including sound insulation.
Due to the highest sound absorption (up to 1.0 with a panel thickness of 40 mm and a wall depth of 200 mm), Echocore can be used to create sound comfort in recording studios, assembly halls, restaurants, etc. At the same time, the properties of the source material allow painting products in a wide color palette, give its surface geometric shapes, apply prints and drawings by airbrushing, cut into shaped products. Thus, sound-absorbing panels provide unlimited possibilities in interior decoration according to individual projects.

True, when buying, you should be careful - cases of fake have become more frequent recently, and packages with canvases have received an updated design.
8 Gyproc Aku Line GKL
Professional recommendation. Smoothness and hardness of the front surface
The country: Poland (produced in Russia)
Average price: 680 rubles.
Rating (2019): 4.6
Soundproof gypsum sheets are recommended by the Moscow Research Institute of Physics for use as permanent elements in standard constructions for soundproofing walls and ceilings in residential buildings, including medical and children's institutions. To do this, they have all the necessary set of qualities: strength (provided by a dense core of gypsum reinforced with fiberglass), high sound insulation index (54 dB), environmental friendliness (confirmed by EcoMaterial Absolute).
The front surface of the sheet has a hardness that is significantly superior to that of competitors, and the special shape of the edge increases the resistance of the seam to cracking. It is important to note the exceptional smoothness of the cladding, which significantly reduces the time and material costs for finishing. The reviews confirm that the sheets are really very dense, it is quite difficult to transport them, and it is better to countersink the holes before tightening the screws. But sound insulation, subject to the use of material according to ready-made solutions for specific premises, is achieved tangibly.
7 Knauf Acoustic KNAUF
Environmental friendliness. Effective service life of more than 50 years
The country: Germany (produced in Russia)
Average price: 912 rubles.
Rating (2019): 4.7
AkustiKNAUF is an acoustic mineral wool created using the innovative Ecose technology, which eliminates the use of harmful substances based on phenol-formaldehyde resins as a binder. In addition, synthetic dyes are not introduced into the composition, and the characteristic brown color of the canvases is the result of exposure to high temperatures on the natural components of the raw material. Compared to other products, Acoustic has longer and thinner fibers, due to which a higher sound insulation rate is achieved - according to the test results, a finished partition using KNAUF materials reduces the noise level to 57 dB (the indicator also depends on the wall design).
On the basis of AcoustiKnauf, the company offers many ready-made solutions for heat and noise insulation of various objects. Their implementation is simple due to the availability of detailed instructions from the manufacturer, with which you can isolate the room yourself or control the work of the contractor. Proper installation provides maximum stiffness, resilience and recoverability, so that the predicted service life of the material in the partition wall is 50 years or more.

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. It is allowed to carry out soundproofing only of internal rooms with low humidity. Panels can be cut 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.
4 StopZvuk PSU
The best combination of noise and heat insulation properties
Country Russia
Average price: 755 rubles.
Rating (2019): 4.8
To minimize the cost of heat and sound insulation of a house or apartment, you should pay attention to StopZvuk BP plates. The material has unique abilities due to the presence of basalt mineral in the composition. This component plays the main role of a universal insulator. In addition to a high rate of sound absorption (up to 99%), the plate withstands high temperatures (up to 1000 ° C). Owners of private houses will benefit from such properties as resistance to rodent penetration, preservation of their properties in a humid environment, and inertness to biodestruction.
StopZvuk BP is an environmentally friendly material, since basalt is a natural substance. The products meet all the requirements of European standards. Quality is controlled at all stages of production.
The low density of the material allows for complete heat and sound insulation of a house or room, without fear for the load on the supporting structures. Sound insulation is mounted in the same way as in the case of mineral plates. A frame is made with a step of 600 mm, and an insulator is placed in the formed space.
Homeowners note in the reviews such advantages of StopZvuk PSU as lower costs for a set of insulation measures, simple installation, and light weight. The disadvantages include insufficient protection from strong noise and vibration.
3 Shumanet BM
Best price
Country Russia
Average price: 749 rubles.
Rating (2019): 4.8
Shumanet BM mineral slab will help to cheaply make high-quality soundproofing of a room. This non-combustible material has a low specific gravity, which reduces the load on the walls. Plates are designed to fill the voids between the wall and the cladding. Installation is carried out using frame structures. The quality of each plate is strictly controlled by the manufacturer. Therefore, excellent acoustic properties are guaranteed.
Builders have no problems with the installation of material. As a rule, a frame with a pitch of 600 mm is arranged on the walls of houses. The miniplate has the same width with a length of 1200 mm and a thickness of 50 mm. The package contains 4 plates, which allows you to immediately isolate 2.88 square meters. m walls. Soundproofing material is laid between the profile or wooden beam. For fastening, it is enough to use several plastic "fungi" intended for mounting heat-insulating plates. If Shumanet BM will be used in rooms with high humidity, then each plate is wrapped in a non-woven material, such as spunbond.
Russian homeowners and builders note a number of positive qualities of soundproofing material. This is an affordable price, ease of installation, good noise absorption coefficient. The disadvantages include the presence of loose and prickly elements.
2 Soundline-dB
Optimal combination of thickness and sound insulation properties
Country Russia
Average price: 1080 rubles.
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, high degree of sound insulation (up to 69 dB), preservation of its properties up to 25 years, low cost.
Installation of triplex is in many ways similar to the creation of plasterboard structures. 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.
1 ZIPS-III-Ultra
Best Sandwich Panel
Country Russia
Average price: 1525 rubles.
Rating (2019): 4.9
The use of the ZIPS-III-Ultra sandwich panel allows you to comprehensively solve the problems associated with extraneous noise. Due to the exact size of the sheet (1200x600x42 mm), any homeowner will quickly calculate the need for a particular room. It is also worth considering that the kit comes with the necessary set of hardware for fasteners. These are traditional dowels, anchors, washers and self-tapping screws. The soundproofing system itself is a combination of gypsum fiber and staple fiberglass. The role of the support is played by 8 vibration isolators. They protrude in a free state by 10 mm in relation to the plane of the sheet. During installation, they are pressed with drywall. As a result, the total thickness of sound insulation and plasterboard is 55 mm.
To install a soundproofing layer on the walls, you need to stock up only with a puncher, a screwdriver and a hacksaw. Thanks to the frameless system, it will be possible to save on the crate. The sandwich panel comes with clear installation instructions. The sound insulation layer can be covered with ordinary plasterboard sheets.
Domestic owners of apartments and houses call ZIPS-III-Ultra panels the best soundproofing option. It is efficient, inexpensive and thin. After soundproofing, many managed to forget about loud neighbors, their dogs and sounds from a busy street.
If there is even an ordinary road near your house, you do not need to explain how it affects the human nervous system. Even in the best case, it will cause people constant irritation and increased nervousness. It should be remembered that they are measured in decibels (db). According to sanitary standards, at night this figure should not exceed 30 dB, and in the daytime - 40 dB.
A variety of which are produced in many by modern industry will help to achieve this result.
A little about soundproofing
The task of such materials is to protect the room from the penetration of unnecessary noise into it. Part of the sound is delayed and scattered, and part of it is reflected and goes back to the external environment. The soundproofing qualities of the building itself are characterized primarily. The thicker they are, the less likely it is that air vibrations will be able to transfer their energy. The ability to "eliminate noise" is indicated in the form of a sound insulation index, which for ordinary residential buildings should be equal to from 52 to 60 dB. Concrete and brick, normal logs and glued laminated timber have a good ability. Drywall, for example, does not absorb sound well, but has decent reflectivity. By the way, about her. What soundproofing materials are really good at blocking noise, and not just reflecting it, creating a resonance already inside the room itself?
Sound absorption
Sound absorption is characterized precisely by the ability to completely neutralize and dampen wave vibrations. Compounds that have these characteristics are granular, fibrous, or cellular. As in the previous case, the soundproofing characteristics of materials are evaluated using an indicator called, as you might guess, the sound absorption coefficient. The spectrum of this value is not too wide: from 0 to 1. If the sound is completely reflected, the value of the indicator is "0", if it is completely absorbed - "1". High-quality materials for interior decoration of the house are distinguished by the soundproofing ability of materials with an index of at least 0.4.
The simplest sound-absorbing materials
The use of absorbent materials is not necessarily reserved for professional builders. So, the simplest fiberglass, which can be purchased at almost any building supply store, can successfully replace professional counterparts. Even by laying a thick carpet on the floor of the room, you can get rid of the annoying echo. Even in cases where these options are not viable, there are ways to significantly "calm down" the environment: furniture with thick upholstery absorbs a lot of noise, as well as heavy curtains, and other types of drapery.
Of course, if possible, it is better to provide more effective ways to protect against noise. Acoustic baffles with absorbent materials can be purchased for use in rooms where loud sounds are generally not allowed (baby nurseries). Most of these screens were developed by designers and engineers in such a way as not to “overlap” the general style of housing design. In a word, this is an excellent soundproofing material for the walls in the apartment. Unfortunately, you can not find it in every building supermarket, and the cost is not very humane.
Comfortable noise level. What threatens the increased
Scientists have found that the average person is most comfortable at 25 dB. If the value is lower, then there is a “ringing” silence familiar to many, which causes a feeling of psychological discomfort. As a rule, in the city, people calmly tolerate a noise level of 60 dB, but with permanent residence in an area with a value of this indicator of 90 dB, insomnia sets in, which quickly develops into neuroses that can result in serious mental disorders. At 100 dB and above, there is a threat of complete hearing loss. To protect against such unfortunate consequences, soundproofing materials are just the same. They are soft, semi-rigid and hard.
Solid Type Characteristics
As a rule, they are made on the basis of granular but there are exceptions. So, there are materials that include natural pumice, "foamed" perlite, vermiculite. Their sound absorption coefficient is 0.5. The mass of such materials should not exceed 300-400 kg/m 3 .
Soft varieties
Again, they are made on the basis of the same mineral wool, as well as fiberglass. However, technical varieties of ordinary cotton wool are used much more often, felt is also very popular. For these materials, the sound absorption coefficient can vary from 0.7 to 0.95. Of course, they are much lighter than the previous variety: their weight does not exceed 70 kg / m 3.
Semi-rigid variety
In this case, soundproofing materials for an apartment are meant, made of glass wool or mineral fiber, as well as synthetic materials. For example, polyurethane foam is often used in this capacity. Semi-rigid varieties also have a fairly high sound absorption coefficient, which can range from 0.5 to 0.75. The mass can reach 130 kg / m 3, but more often does not exceed 80 kg / m 3. Thus, in most cases, it is recommended to use soft varieties, which, with a minimum mass, have an excellent sound absorption coefficient.
How to choose the right material for a living space?
However, the choice of the “right” material also largely depends on what kind of sounds interfere with being in the room. Thus, the operation of electrical appliances creates the so-called airborne noise (vacuum cleaners, hair dryers, computers). If we are talking about walking, various kinds of construction work, and so on, it means shock-type noise. In our conditions, it is also not uncommon for a house built without the use of normal soundproofing materials and assembled on a rigid frame to turn into one big source of sound pollution. In this case, we are talking about structural noise.
Soundproofing materials with a cellular structure (pumice stone, polystyrene foam) perfectly cope with shock loads. Airborne noise, which is most typical for most residential premises, is perfectly damped with the help of fiber boards or their analogues. Alas, structural violations can be dealt with only after the analysis of the main structural elements and the use of special gaskets with good soundproofing qualities.
Eliminate airborne noise
You should know that the main characteristic for materials with the ability to absorb airborne sound is the so-called sound absorption index (Rw), which is expressed in decibels. Remember: in order not to hear the speech of the household behind the wall of the room, it is important that the soundproofing properties of the materials (used in the construction of the partition) be equal to a coefficient of at least 50 dB. We have already talked about the sound absorption coefficient: the closer it is to unity, the better. For living rooms, this indicator should not be lower than 0.5.
The most reliable way to protect against unnecessary noise is to install dense and massive interior ceilings. Best of all in this case, foam concrete blocks and concrete with inclusions of a sufficient volume of expanded clay have proven themselves. It is important that the walls are truly a monolithic structure. No cracks or holes are allowed. It should be remembered that different soundproofing materials for walls can be used in one design, provided that there is a strong and monolithic connection between them. This is achieved with the help of a quality solution. A "canonical" example is a foam block wall, separated by facing bricks or artificial and / or natural stone.
It is important, however, to take into account the fact that the construction of such structures in an already occupied building is an extremely complex and non-trivial task. In addition, if the house itself is built from low-quality materials, such a measure will reduce noise by only 10-15 dB, which is not enough for normal sound insulation.
It is much easier and cheaper to make a partition based on sufficiently strong and rigid structures using various types of sound insulation. If we compare soundproofing materials in this case, then you will not see much difference even with cork flooring ...
In this case, not only a brick or foam block can be a rigid base, but even ordinary drywall based on a wooden beam, for the manufacture of which a properly dried tree was used. The higher the density, the better the soundproofing ability of the material. Of course, the layer of soft materials will play the main role in stopping noise. As we have already said, in residential premises it is most advisable to use their fibrous varieties, like mineral wool or fiberglass boards: they most effectively absorb airborne noise.
It should be remembered that in all cases the effective thickness of the partition should not be less than 50 mm. And further. At least 50% of the entire internal volume of the partition must be left for soundproofing materials for the walls, otherwise you will not be able to get high efficiency. Now let's talk about specific varieties.
glass wool
Made from regular fiberglass. Its main characteristic is high strength, as well as elasticity and vibration resistance. Many soundproof flooring materials are made from pressed glass wool. Its characteristics are due to the fact that there are a large number of air spaces between the fibers. Glass wool has many positive qualities: it is absolutely unaffected even by an open flame, has a very low weight, does not absorb moisture with excellent vapor permeability. In addition, cotton wool is chemically passive and does not cause corrosion in those metals with which it comes into contact. This is very important in this case, since many soundproofing materials for walls are made on its basis. When repairing an apartment with its help, it is only important to remember that the ingress of the smallest particles of glass wool into the respiratory system is highly undesirable, and therefore it is necessary to use a good respirator.
Mineral wool
Perhaps it is known to every builder. It can be made from melts of (silicate) rocks, as well as from slag, which is a waste of metallurgical industries. As in the previous case, the material is not susceptible to open fire, and also does not cause corrosion of metal structures with which it comes into contact. Excellent sound absorption abilities are due to the presence in its composition of a huge number of fibers located in an absolutely chaotic, intertwined form.
Important note
Mineral wool and fiberglass should not be confused, as the characteristics of their fibers are different. For glass wool, its length is at least 5 cm, while for mineral fiber this figure does not exceed 1.5 cm. In addition, the first material (mineral wool) is noticeably lighter, and its cost is somewhat lower. In particularly noisy rooms, it is often necessary to arrange the so-called acoustic ceiling: elements reflecting it will reflect excess sound, while soft materials will effectively absorb it. The latter are placed in the space between the "native" ceiling and the outer layer of the acoustic coating.
Manufacture of a sandwich panel
To simplify the work, they take ready-made elements of the ZIPS system. They can be used as effective soundproofing for single-layer walls made of solid materials (brick or concrete). Structurally, such panels are very simple, as they consist of sandwich panels and covering material in the form of drywall. The “sandwich” itself consists of the same drywall, which is interspersed with layers of mineral wool or fiberglass. It is important that special models with different thicknesses of the “acting material” can be selected for different rooms. In particular, some soundproofing materials for doors are made according to this type.
The advantage of such panels is that, having no metal frame, they are extremely light in weight and can be attached to the wall using ordinary screws of a suitable length. Note that it is advisable to place a special gasket for sound insulation between a load-bearing wall or even a partition. Unlike previous materials, ZIPS belongs to the category of poorly combustible, which limits the use of panels in baths and other rooms where there is a possibility of their contact with an open flame.
Depending on the model, the thickness of such material can reach 13 centimeters. With this indicator, the sound insulation index is 18 dB. Thus, when hanging ZIPS of such thickness on the wall of a typical living space, the degree of sound protection can reach 63-65 dB. Please note: it is possible to use such soundproofing materials for walls when repairing an apartment only if the load-bearing structures are sufficiently strong, since the mass of a square meter of ZIPS can reach 21 kg, or even more.
How to protect yourself from impact noise?
In this case, it is necessary to use such structures that could repel and scatter sound waves, and not absorb them. Porous, elastic materials are suitable for this purpose. The most commonly used option is with special linings, which are laid at the stage of installation of the finished floor.
Cork lining
Uniquely resistant to mould, fire, fungus and rodents. Very inert in chemical terms, completely safe for any type of metal structures. The service life can exceed 40 years. The highest quality varieties can reduce the level of impact noise immediately by 12 dB. Alas, the cost sometimes crosses out all the advantages of the material, since they ask for five or six dollars per square meter. At the current rate, this is a little expensive ... If not for this circumstance, cork floors could be described as "the best soundproofing materials."
Polyethylene foam
A more "budget" option for impact noise protection. Foamed polyethylene has a density of 20 to 80 kg / m 3, which makes it possible to use it in almost any type of residential premises. It has several varieties at once:
- Uncrosslinked. Molecules of a substance are not connected to each other by chemical bonds. The cheapest variety allows you to reduce the noise level by three to four decibels.
- Physically stitched. Some of the molecules form a rather dense structure. Due to this, the soundproofing properties of this type of replacement are higher (allows you to reduce noise by five to six decibels). Based on this type, some soundproofing materials for the ceiling are made.
- Chemically crosslinked. Molecules have a strong chemical bond with each other. Due to this, the material has indicators that are only slightly inferior to those for cork lining.
Regardless of the type of polyethylene, it is good to use it when installing a concrete screed; it is placed under a parquet board and laminate. In some cases, it can be used to strengthen joints. Physically strong, resistant to many chemicals. Flammable, and therefore should not be used in those rooms where there is an open flame. Under the influence of ultraviolet radiation quickly loses its protective properties. It is undesirable to lay such a substrate in private rooms, since it wears out quickly under strong mechanical loads. It does not allow moisture to pass through, which in some cases creates prerequisites for the development of mold. Despite this, many soundproof floor materials (linings) are made on its basis, since the cost of polyethylene is very low.
