Acoustic foam rubber for automobiles. Do-it-yourself acoustic foam installation: recommendations The main types of rooms for soundproofing

Acoustic foam rubber is considered to be the most effective material for device high-quality sound insulation premises. It perfectly dampens (absorbs) sound waves and significantly improves interior acoustics. Soundproof polyurethane foam has other advantages, these are:

  • flexibility and light weight, so that the installation of panels is not difficult;
  • environmental friendliness;
  • resistance to mechanical stress;
  • lack of smell;
  • original appearance that does not require additional finishing.

Acoustic foam rubber is produced in the form of rectangular panels of a standard size of 1x2 m, with a relief in the form of a pyramid, peaks, waves. Their scope is inclined, vertical and horizontal surfaces of any shape.

Installation of acoustic foam rubber: workflow

  • prepare the surface to be glued. Level and clean it of dust and debris. Walls made of laminated materials and concrete sand and prime;
  • draw up on paper a layout of foam rubber sheets and, in accordance with it, mark out the wall and ceiling. Mark cut lines on the material. Since acoustic polyurethane foam has a textured pattern, it is better to determine in advance the location of the cuts and adjust everything so that they are inconspicuous and look beautiful. Attention: glue from the middle of the ceiling or wall;
  • treat the foam with adhesive. Use an atomizer or spray gun to apply the adhesive to cover the surface of the material with a thin layer. A brush or spatula can create a thick layer when smeared and the foam will "slide" down the surface after gluing. Spot application of glue is also allowed, but with this method of fastening, the material does not use its full sound-absorbing potential. Attention: to work with acoustic polyurethane foam, choose contact adhesives on a butadiene-styrene, neoprene basis. Means containing trichloroethane are not suitable for fixing foam rubber on the surface;
  • press the foam sheet treated with adhesive to the surface at a predetermined place. Wait for the glue to set. Fix the rest of the panels to the wall in the same way.

Shops of the company "Vinyl Tex" carry out acoustic wholesale and retail from 1 sheet. Consultation of the manager and acceptance of the order by the phone number indicated on the website page.

Any multi-apartment housing assumes the presence of many different extraneous sounds. They can not only distract, but also affect the state of human health. Therefore, it is important to create comfortable living conditions in your home, which will not be affected by external factors.

One solution to this problem is soundproofing the ceiling and walls. For such work, several approaches and materials are used, among which special attention should be paid to acoustic foam rubber.

Basic concepts

Conventionally, all materials today can be divided into sound-absorbing and sound-reflecting. Acoustic foam rubber belongs to the first group of substances that are capable of qualitatively scattering sound waves inside their structure. It is made from polyurethane foam or polyester, which during technological processes turn into a light porous material.

But this product should not be confused with ordinary foam rubber, as they have many distinctive properties.

Some of the benefits of this product include:

  • Quality absorption a wide range sound waves. There is practically no sound reflection, which allows you to get pure vibrations inside a certain isolated area (living room, recording studios, and so on).
  • Simplicity and versatility. The material can be attached to almost any type of surface. But often acoustic foam is used for ceilings to minimize external noise load. Installation of foam rubber does not require special skills and can be carried out even by an untrained specialist.

  • Damage resistance. The substance does not rot, and also does not collapse under the influence of various fungi and microclimatic factors. This allows the foam rubber to be used for a long time.
  • Unique design. Panels can be added different structure and color shades. Therefore, they are very often not closed, as they fit well into the overall style of the room.

But acoustic mats are not capable of absorbing low frequency sound. Therefore, you need to additionally use special "bass" traps. Such a complex is used only in recording studios, where the quality of acoustics plays an important role.

Usage environment

Soundproofing rooms is not always necessary. If the noise level is significant, then you can resort to the installation of protective acoustic systems.

Foam rubber of this type is used as soundproofing material in various places:

  • Industrial premises. It is especially common in places where there are many different machines that emit not only noise, but also vibration.
  • Mechanism cases. Foam rubber is very often inserted inside industrial air conditioners, as well as in diesel generators. But their service life is limited, as the material is quickly clogged with dust.

  • Movie theaters, television and so on. In such places, acoustic foam rubber is almost always used to soundproof ceilings and walls. Recording studios create "clean" rooms where you can hear and record your own voice without impurities.
  • Residential houses. Quite often in panel-type buildings the noise level is high. It spreads in most cases through the ceiling or walls, which are covered with such a substance.

Substances of this type are universal material. It should be understood that its characteristics do not depend on the place where the foam rubber is attached.

Principle of operation

Acoustic foam has a porous structure. But her distinctive feature is the presence of open pores, which are interconnected by microscopic channels.

The principle of absorption of sounds by this substance can be described by several actions:

  • The sound wave hits the top layer of foam rubber. Often it has an uneven surface. This causes the flow to fight back and penetrate the structure.
  • The sound, getting inside the pores, begins to change the direction of its movement and begins to fade. This is achieved due to different air resistance, which reduces the amplitude of the waves.

Please note that the quality of noise reduction depends on many physical characteristics foam rubber. Some of them are designed to work with medium, and some with high frequencies. You can only check with the manufacturer of this product for specific specifications.

Types of foam rubber

Technical characteristics of foam rubber depend on its surface structure. Depending on this, 2 main groups are distinguished:

  • Embossed panels. The top layer is smooth, without any protrusions. This type of plate is universal, as it is used to eliminate all types of sounds. They are rarely used indoors. From such foam rubber, soundproof screens are created that protect people from noise on highways. To extend the life of these structures, foam rubber needs to be periodically cleaned of dust.

  • Embossed panels. The main purpose of these products is the fight against noise, as well as the qualitative correction of acoustic indicators indoors. The substance absorbs sound waves well. Another advantage of embossed foam can be considered the ability to suppress vibrational impulses. They can work with waves of different power.

The top layer may differ in the presence of various profiles. Today, foam rubber is presented on the market in the form of a “wave” and a “pyramid”. But some manufacturers give it a different structure, which changes the properties of the product.

The color shades of these products may vary depending on the needs of the client. But many manufacturers produce black or gray foam, as in most cases it is hidden behind the finishing layer.

The thickness of the foam boards can also vary. Today, this value varies in the range of 5-100 mm. This parameter affects the sound-absorbing parameters, which allows you to create the necessary indicators inside the rooms.

Mounting technology

Many experts say that it is possible to increase sound insulation in an office or residential area by installing foam rubber plates on the ceiling.

This process is relatively simple and is carried out in several consecutive steps:

  • Formwork construction. The same approach is used here as for wall cladding. thermal insulation materials. Several wooden planks are nailed to the ceiling. The distance between them depends on the size of the panels themselves. It is desirable to align all planks in one plane, which will simplify their further finishing.

  • Ceiling cleaning. Theoretically, foam rubber can be glued to any material. For this, special adhesives are used. But if the base is heavily contaminated, then it will not be possible to form a strong bond between the components. Therefore, it is advisable to thoroughly clean the ceiling before fixing the material.
  • Foam fixing. The process is relatively simple and involves applying glue to the surface of the ceiling, followed by fixing the material. It is only important to evenly distribute the composition in order to ensure a strong bond.

Everyone who is engaged in sound engineering and arrangement in an acoustically unprepared room sooner or later comes to the idea of ​​the need to “drown out” the room. There are many "folk" and, by the way, effective means:

  • Lots of upholstered furniture in the room
  • Bookcase
  • blackout curtains
  • Carpets on walls and floors

However, in most cases this is not enough. For example, when recording a voice, even in a filled “living” room, “echo”, resonances (“bank”) are felt, which often makes it impossible to further process and use the recorded material.

There are at least 2 ways out of this situation:

  1. Professional preparation of the premises
  2. The invention of the "bicycle"

As inquisitive and greedy minds, we will not take path 1. (about 700 euros per 1 m2 of premises), although it is the most correct one. We will try "on the knee" to collect acoustic design living room with low material costs.

We will need:

  1. Foam rubber 30-100 mm or foam-pyramid 70 mm
  2. IKEA padding blankets or similar material
  3. Metal braided cord (cable) with a diameter of 3-4 mm
  4. Carabiners for pulling a metal cord
  5. Nylon braided cord with a diameter of 5 mm
  6. Screw hooks 8-10 mm, dowels
  7. Perforator, drill
  8. Stepladder (preferably two when working together)
  9. Sharp knife for cardboard / paper (cut foam rubber)

The cost of materials is from 30 to 40 tr. (except 7.8)

It is better to work together, this increases the assembly speed by 3-4 times. If the area of ​​\u200b\u200bthe room allows - (more than 30 m2) - then the three of us.

Graphic plan

Those. in fact, we hang the panels on the walls like curtains, and on the ceiling we simply lay them on cables. Why can't foam rubber be glued to the ceiling - yes, because foam rubber generally does not normally stick to anything without changing its structure (primer, chemical soldering, etc.).

Stages of work:

  1. Marking the position of the "hooks" on the walls
  2. Drilling, installing hooks
  3. Stretching a metal cable
  4. Assembly of “panels” foam rubber + blankets 1m by 1m or other convenient size up to 1m by 2m by stitching with a nylon cord
  5. Attaching panels to the wall
  6. "Throwing" and threading panels on the ceiling on stretched cables
  7. Alignment of panels and additional stretching.

Special attention:

  1. Cord fastening of “wall” panels - there is a high risk of foam rubber rupture, so the distance between the cord entries (Fig. 2) should be greater, you can also make a bundle through a plastic plate to reduce foam rubber stress at the attachment points. An even more reliable option is to nail foam rubber to wooden lath and cling to the rail.
  2. Sockets - should get to the junction of the synthetic winterizer or immediately provide for the absence of a synthetic winterizer on the outlet (it is difficult to “gnaw through” to the outlet).
  3. Chandelier - calculate the hit of the chandelier on the joint of the panels, cut a recess for it and use ONLY ENERGY SAVING LAMPS, because. they heat up a little and will not be able to melt (or, God forbid, set fire to) foam rubber.
  4. 2-3 days - ventilate the room from the "smell" of foam rubber.
  5. The room must be empty for the convenience of assembling the panels on site.



For better dispersion, the fact that the foam rubber goes in waves and sags a little is in our favor, in any case, it is important to avoid excessive stress on the foam at the attachment points!

When using dark foam rubber in the room it will become very dark - use additional lights and light curtains.

In the room it is desirable:

  • availability of upholstered furniture
  • filled corners (furniture, closet)
  • carpet on the floor
  • thick curtains on the window

results

Now you can enjoy listening to music in the room on acoustics up to 100 watts, there is significantly less echo, voice recording is much better, comparable to studio recording. Important - the ceiling is not damaged, theoretically - the panels can be installed elsewhere.

Hygiene

With blankets, everything is clear - they are hygienically safe. With foam rubber - this approach: you need to buy "furniture" foam rubber and require a hygiene certificate. It is also important that the room has normal humidity, because. this significantly affects the quality of the foam rubber "to break".

Foam rubber, known in the scientific world under the name - very amazing and interesting stuff, firmly embedded in modern life person. Almost all people daily deal with certain types of foam rubber, but few people know the history of the origin of this amazing material.

It all started back in 1929, when at Dunlop one of its researchers received the first samples using latex. Ten years later, foam rubber was first used to form rubber foam from isocyanates, but soon most of the natural varieties of foam rubber were replaced by styrene-butadiene rubber. At the same time, it began to be widely used for commercial purposes for the first time.

Polyurethane foam received its current name "foam rubber" thanks to a supplier company in the days of the USSR, which has the name "Porolon".

To date, most of the polyurethane market is made up of polyurethane foams.

The largest consumers of all kinds of foam rubber are:

  1. Transport. In almost all modes of transport (airplanes, cars, trains, ships, etc.), one way or another, there are elements based on foam rubber.
  2. Construction. Without a huge variety of polyurethane, it is impossible to imagine any construction site today.
  3. Furniture manufacturing.

One of the common properties of foam rubber is its ability to absorb sounds. It is thanks to this property that it became possible to create rooms that have acoustic purity and protection from the effects of extraneous noise.

Acoustic foam rubber is used in the arrangement of home and professional recording studios, as well as production workshops of industrial enterprises.

Foam rubber action method

Noise is essentially the sum of sound waves in the frequency spectrum. Waves, having reached physical bodies, are absorbed or reflected from them. A smooth wall in the room reflects a wave of sound, which begins to maneuver between obstacles - this is how the echo known to everyone since childhood is obtained.

Carpets or cushioned furniture reduce the energy of the sound wave by partially absorbing it and converting the effect of friction into heat. And the presence of all kinds of clusters of various objects and smooth surfaces is one of the reasons for significant sound distortion.

It was to equalize the load of noise in the rooms that sound-absorbing foam rubber was created. When examining it under a magnifying glass, you can see that the structure of the foam rubber is formed by countless polyurethane cells, inside of which there is air.

The official name of foam rubber is elastic polyurethane foam. It is a material with an open cell structure, thanks to which it is easily able to absorb liquids and absorb air. The wave of sound, upon reaching the average thickness of the foam rubber, is repeatedly reflected from its micropores and loses all its own energy (up to complete attenuation). For this reason, the higher the density of foam rubber and the smaller the cell size, the higher its sound insulation properties.

The main types of rooms for soundproofing

Consider the main rooms, the sound insulation of which is of practical importance.

Such premises include:

  1. Residential house/apartment
  2. Sound recording studio

Office- place of high concentration a large number people who perform certain duties and create serious noise pollution. For example, phone calls, knocks and squeaks office furniture, the noise of steps, the work of various office equipment (computers, printers, etc.). All this creates an atmosphere in which employees' productivity decreases, absent-mindedness and fatigue increase. A significant reduction in noise levels (almost twice) can be achieved by placing several foam panels on a cabinet or cabinet shelf.

Residential building, apartment is a place to relax, recuperate after a hard and difficult day at work. However, if the house is located on a busy street, and the owner has begun repairs in the apartment next door (or an ardent fan of loud music lives in the apartment on the next floor), rest becomes an unattainable dream, because it is impossible to fully relax in such conditions.

Sound-absorbing boards can help in solving this problem - they perfectly cope with the penetration of extraneous sounds into the room, not only from the outside, but from the inside. Especially acoustic insulation is useful for those who have small children - it will help maintain an atmosphere of calm and comfort.

Recording studios almost impossible to imagine without sufficient isolation from noise. Any extraneous noise and sounds adversely affect the quality of the recorded sound. For this reason, acoustic panels are installed in them not only on the walls - the ceiling is also processed.

Types of acoustic foam

In the process of designing the acoustic space of a room, one should not forget about the rules, following which the maximum effect will be achieved (elimination of sound reflections, the required sound level of acoustic systems).

Acoustic foam panels can be divided into two main categories:

  • panels for absorption of low frequencies (abbreviated - LF)
  • panels that absorb medium and high frequencies (abbreviated as C / HF).

Accordingly, panels of the first type act mainly on the absorption of low frequencies and are implemented in the form bass traps and cubes. Absorbers of medium and high frequencies are represented by acoustic panels of the type "Pyramid", "Wave" etc.

bass traps

First of all, the false claim about the "outstanding abilities" of this type of panels should be dispelled, because some people believe that bass traps are capable of absorbing low frequencies. The main task of acoustic foam rubber is the elimination of reflections sound signal and the reduction of its "tails".

If you need to completely remove a certain frequency of sound, acoustic foam will not help. Its task is to remove the consequences of problematic frequencies in space.

Since low frequencies accumulate in the corners of the room, returning to the listener with a certain delay, the main function of bass traps is to eliminate the accumulation of low energy.

Moreover, the relief of the panel does not matter. The size of the acoustic panel of this type depends on the size of the room and the planned result.

Acoustic foam panels

When choosing a panel, it should be remembered that its properties will directly depend on the weight and shape of the panel. For example, the Wave relief gives the softest sound-absorbing effect. These panels can completely cover the room.

But the Pyramid panels give the best result when a small amount and are located in certain areas of the room. Foam rubber of this type is widely used in acoustic systems- as a replacement for an ordinary synthetic winterizer, which fills the space inside the speakers and subwoofers. It gives improved sound waves of medium and high frequency range.

Other acoustic panels differ mainly in the shape of the relief and certain degrees of efficiency. They perfectly cope with the problems of premises of any size - from small offices to production-level premises.

Working with acoustic foam rubber does not require special skills or abilities. It is easy to cut and, due to its low weight, can even be attached to 2-sided tape.

Soundproofing features and means to reduce unnecessary noise

There are two approaches to sound reduction: the use of anti-noise generators of the active type or increasing the distance from the source to the sound receiver using sound barriers that absorb the energy of sound waves.

Some factors of propagation and absorption of sound waves should be taken into account:

  1. Distance. The energy of sound waves scattered over a distance is reduced if acoustic foam is used - it gradually reduces the intensity of sound waves in the source, while in a normal situation, the rate of attenuation of sound waves is inversely proportional to the distance from the sound source.
  2. Damping. As a damping agent, acoustic foam is quite effective, as well as for reducing room resonance, absorption, diffusion or reflection. The absorption of sound by acoustic foam panels helps to reduce the sound level, while diffusion or reflection converts unwanted sounds into useful ones (due to their coordination).
  3. Absorption. Sound-absorbing foam materials, as mentioned above, convert the energy of sound waves into heat while reducing them. Sound absorption in certain frequency ranges is especially important in listening rooms or recording studios.

Porous acoustic panels

Acoustic foam absorbers with open pores operate on the principle of absorbing noise in the structure of the material. They are an effective noise absorber in the C/HF range. The absorption coefficient of foam acoustic panels is impressive even at low frequencies.

Sound absorption factors of cellular acoustic foam rubber:

  1. Foam density.
  2. Cell dimension.
  3. The presence of convolutions and bends.
  4. Panel thickness.
  5. The number of pores in the material.

Resonant Type Absorbers

Panels of this type, as well as Helmholtz resonators, act by damping (reflecting) sound waves. Absorbers of this type, compared to porous ones, are especially effective for frequencies of the medium and low frequency range, but they are distinguished by a high cost compared to acoustic foam rubber.

Soundproofing with foam rubber in everyday life

The influence of external noise can be easily reduced or eliminated in the domestic environment. The main focus in sound insulation in modern houses should be given to windows.

To muffle the sound, in addition to curtains, honeycomb air chambers can be used or through the use of acoustic foam rubber. Honeycomb structures with a number of cells from 1 to 3 make it possible to achieve a high degree of sound attenuation.

In addition, acoustic foam panels can be part of the ceiling or walls - to reduce the sound level from neighboring apartments. In this case, foam rubber can be installed as a separate layer on the ceiling or walls.

Soundproofing with foam rubber in commercial premises

In the same way of installing acoustic foam rubber, the effect of reducing noise in rooms with a large number of employees and office equipment (telephones, computers, etc.) is achieved. Noise reduction, as already mentioned above, contributes to an increase in the efficiency and productivity of employees. In production shops, acoustic foam gives a noticeable reduction in overall volume and sound reflections from operating equipment.

Features of installation work

When carrying out work on the installation of acoustic foam rubber, the following rules must be observed:

  1. The foam panel should not be wrinkled or deformed, as this significantly reduces its effectiveness.
  2. Attach the foam rubber to the base with glue or double-sided tape. You can read about which glue is better in the article.
  3. Foam panels are installed exclusively for indoor installation.
  4. As a rule, the panels are placed under the floor covering, inside the walls or in the false ceiling structure.

The thickness of the sold foam panels can vary from 5 to 100 mm. When choosing a thickness, you should choose panels according to the principle: “higher noise level - thicker sound insulation layer”. For houses, apartments or office premises, panels with a thickness of 50-70 mm are suitable.

Standard panels are gray or brown, however, if desired, panels can be ordered in the desired color or shade.

Approximate price of various types of acoustic foam rubber

  • Pyramid(the shape of pyramids) - the price is 600 rubles. per square meter.

  • Wave(smoother shape in the form of a wave) price 400 rubles. per square meter.

  • Aura- price 450 rubles. for a set of four squares, each 30x30 cm.

  • small bass trap- price 900 rubles. for 1 piece. Dimensions 50x30x30 cm.
  • bass trap big- price 1700 rubles. for 1 piece. Dimensions 100x30x30 cm.

In conclusion, it is worth mentioning the fact that foam rubber is not demanding on operating conditions and is an almost eternal material.

Recently, acoustic foam has always been on guard for silence and purity of sound. It got its name from the Porolon company, the main supplier of polyurethane foam at the time Soviet Union. It was first made in 1929.

Today it is used in recording and editing studios, theaters, television companies, restaurants, as well as in apartments, cafes, restaurants, offices. In short, wherever it is necessary to prevent chaotic sound vibrations or noise pollution.

Beware the noise!

Noise is a set of sound waves that are able to transfer their energy to physical bodies and be reflected from them. BUT noise pollution- acoustic vibrations of different origin and spectrum, whose intensity and energy violate the acoustic comfort. These fluctuations can come from outside and form within premises. And internal are more dangerous than external. After all, the noise coming from the street is kept by the walls of the building and double-glazed windows. And there is almost no protection from internal noise in the room.

The only thing that can neutralize the internal noise load is soundproofing rooms with acoustic foam. It eliminates two types of noise. The first is sound vibrations that propagate between free gas molecules, the second is vibrations.

In other words, acoustic foam prevents the release of vibrational energy that can cause vibrations in solids.

Types of acoustic foam

Acoustic foam rubber is made in the form embossed and reliefless soundproof panels of different shapes, sizes and colors. The first ones are used to combat noise and correct acoustic conditions in rooms. They not only absorb sound, but also suppress those oscillatory impulses that could not be dissipated, neutralize powerful sound waves.

Embossed acoustic panels produce with "wave" and "pyramid" profiles, which give the studio or home cinema an original look.

Second - universal- Eliminate any noise that is created by nearby roads. They improve room acoustics much less than embossed panels, so they are used for soundproofing load-bearing and non-bearing walls, complete and incomplete partitions from any materials.

Acoustic foam rubber: we use it for efficient work in the office

Offices are known to generate and spread indoor noise pollution - footsteps, banging of drawers, doors, furniture, office equipment, phone calls and conversations - even if workers try to be as quiet as possible. All this reduces productivity and makes it difficult to focus on work.

However, if you equip the room with acoustic foam rubber, you can minimize sound vibrations.

According to experts, in small office rooms it is enough to place acoustic foam panels only on the ceiling which will cut the noise pollution by half. And if you also cover the walls (in particular, two neighboring ones), the problem will be solved fully.

Thanks to the soundproofing of the room, people hear and understand each other better. This relieves the nervous system of stress that causes various disorders, including chronic fatigue syndrome.

Video on how acoustic foam works:

Soundproofing apartments with acoustic panels

The apartment is also limited space. Work contributes to its noise pollution household appliances and the movement of people. thin walls reflect sound and transmit it, converting noise energy into vibrations of solid bodies, which causes vibrations., which can also spoil the lives of neighbors.

So in any apartment, especially where a family with small children lives, one cannot do without installing acoustic foam rubber panels.

In addition, vehicles and industrial equipment are powerful sources of sound vibrations.

If your house is located near a factory or a busy highway, you need to install in your apartment sound absorbing panels acoustic foam.

Acoustic foam rubber is an effective remedy not only against noise, but also against sound impulses that are below the limit of hearing. Speech about infrasound, which is very harmful to the body: it negatively affects the heart, kidneys and lungs, and ultrasound, which inhibits biochemical processes in tissues.

Quality sound recording

The main field of application of embossed acoustic panels is the premises where rehearsals are held and phonograms of vocalists' songs are recorded. It's about about recording studios, where acoustic foam rubber can be placed not only on the ceiling and walls, but also on specialized sound-absorbing screens.

This is due to the fact that great attention is paid to the control of acoustic parameters in such rooms: they are tuned to different frequencies.

Installing acoustic foam panels

Acoustic foam panels set exclusively indoors. In particular, their installation is carried out under floor coverings, false ceilings and interior wall cladding.

Acoustic foam rubber is attached with glue or double-sided mounting tape to the base. As an option, you can make a supporting frame from light metal profiles, on which sheets of gypsum fiber are attached, which are the basis for gluing foam panels.

The thickness of the foam panels also means a lot. Today you can buy acoustic foam rubber thickness from 5 to 100 mm, which is selected in such a way as to eliminate not only noise pollution, but also to prevent the propagation of sound waves in the room in order to achieve an ideal, clear and without overlapping sound of the human voice and musical instruments.

In other words, the thickness of the acoustic foam panels depends on the intensity of the sound. That is, the stronger the sound stream, the greater should be the thickness of the acoustic foam rubber. For example, for effective protection of office and residential premises located in the city, several foam rubber panels with a thickness of 50-70 mm are enough.

It should be added that acoustic foam panels are produced in the form of mounting sheets different sizes, which are called mats. The maximum width and length of the mats is 2000 mm.

The price of acoustic foam "Pyramid" for a mat 2 * 1 m is from 1180 rubles (30 mm) to 2500 rubles (100 mm).

Price for acoustic foam "Wave"(1m * 2m) - from 770 rubles. (25 mm) up to 1850 rubles (65 mm).

By the way, the colored acoustic foam "Volna" is produced in gray and dark gray, "Pyramid" - in brown and purple, and when made to order, you can order any color of the panels.

Another important parameter to consider when choosing acoustic foam is material density. Respectively, the smaller it is the better.

It remains to be added that the acoustic foam panels do not require any maintenance and repair, the period of their use is not limited.

The acoustic panel is cleaned with a vacuum cleaner. Its frequency depends on the purpose of the room.

So the ideal sound quality and the absence of noise pollution depend not only on good and expensive equipment, but also on correct finish the room where it is installed with acoustic foam rubber.

Acoustic foam rubber and its application are discussed in great detail in the following video review:
