Acoustic design of the project studio with your own hands. Foam rubber acoustic panels: do-it-yourself silence Pledge of high-quality sound recording

Hi friends. In this article, I will tell and show you how you can do acoustic screen(or acoustic panel) with your own hands is very inexpensive. And for some it might even be cheap.
I personally spied on YouTube how to make such an acoustic screen, and honestly I will attach this video at the bottom of this article. I will share it with you.

What is an acoustic screen for?

A small digression: in relation to the acoustic screen, you can also use the name "acoustic panel" - the essence is the same, so in this article I will use double terminology.

In my course on high-quality voice recording on a computer, in a lesson on preparing a room for recording, I talked about such acoustic panels. If you are planning or have already tried to record your voice on a computer (maybe even purchased), then most likely you have noticed that not every room is suitable for these purposes.

If we take an ordinary room for consideration with you and try to make a recording, then in 95% when listening to the recorded recording we will hear a background echo. And if you are not a koekaker and it is really important for you to do your job with high quality, then you will look for ways to get rid of the echo when recording a voice.

By the way, in my course, I shared a couple of tricky ways on how to solve this problem very simply and easily with improvised means. But this is also not always convenient. Especially if you write not only your own voice, but also the voices of other people who come to you, then it is important to observe the aesthetic component as well.

The echo in the room appears naturally from the reflection of our voice on all sound-reflecting surfaces, of which the room is full (floor, table, walls, cabinet surface).

By the way, in the course of writing the article, I remembered that I had previously raised this topic in, which I had to build in haste at work. If interested, take a look. There, of course, also perfect option, but by 75 percent I managed to cut off the echo.

Recording studios solve this problem with acoustic foam, which sheathed the walls of the studio, sometimes the ceiling.

But for us (mere mortals), this method in most cases will not work for at least two reasons:

  1. Decorating a room with acoustic foam rubber will cost us a fairly tidy sum
  2. and not every room can be safely put under this business.

Actually, an acoustic panel was invented to solve our problem. They are installed behind the microphone and try to protect it as much as possible from echoes.

Here are some sample photos of acoustic panels:

These acoustic screens have their pluses and minuses.

  • Aesthetic component (they look neat and beautiful)
  • Functionality - they do their job well.
  • Cost (they cost a lot)
  • Transportation (not in every city you can buy them)

Here we understand that it would be nice to have such an acoustic panel, but how would you assemble it yourself? Yes or no?

But I definitely somehow thought about it and even made my own acoustic screen. Herself. But, to be honest, I got carried away.

This method has its undeniable advantages, but there are also disadvantages - I will not hide it. If I had known about them earlier, I would have avoided some troubles.

Therefore, I better warn you about them in advance!

But I will tell you about everything in detail below. So, my version of making an acoustic panel with my own hands.

We make an acoustic screen for a microphone with our own hands

And I decided to make a super budget acoustic panel, i.e. with the most minimum investment means for the purity of the experiment.

So, to make a homemade acoustic screen, we need:

  1. The material for the base can be, for example, plywood, but I had the remains of PVC panels, and I took them:

2. Piano loops by the number of connections:

3. Foam rubber 4 or 5 cm (preferably 5).

But I disheveled the backrest from the ottoman (I plan to change it anyway, so why regret it?). My cats, however, did not quite understand me. :)

4. Knife with a thin replaceable blade. I warn you: immediately buy a couple more packs of replacement blades - they get dull very quickly on foam rubber.

5. Door seal (but you can do without it):

6. Black color for water-based paints- Take a few. 4 was enough for me, and then for half the idea.

7. Glue - I took Moment Crystal.

So, I made from panels PVC frame as per my idea:

And along the edges of each constituent parts covered with brown tape.

My cat helped me, I couldn't do it alone.

Now we cut the squares obliquely (from corner to corner) so that we get two triangles from each square:

Well, I also additionally cut off the resulting triangles along the edges, so that it would be more convenient to attach them to each other, well, so that the base of the sound-reflecting foam rubber surface was higher:

I warn you right away, if you choose the same method for yourself with cutting foam rubber, you will have to cut for a long time and a lot, changing far from one blade!

After that, we take a color scheme for water-based paints (not everyone can paint over foam rubber, and we can’t clog our pores either). I had this one:

We breed the color scheme one to one, i.e. 1 jar of color for 1 liter of water. If you add more water, then the color will end up not being saturated, but a dirty gray.

In general, we impregnate pieces of foam rubber with a black aqueous solution and lay them out to dry. Don't forget to buy thick latex gloves! Washing off the color afterwards is quite difficult.

Glue the seal on top, but you can do without this step.

And with Moment glue we glue the dyed and dried foam rubber to the base, more precisely foam rubber triangles, putting them tightly one to one:

Thus, we paste over all parts of the base and connect them to each other with piano hinges ... Although it is possible in the reverse order.

I planned to make a rather impressive acoustic screen in this way, but, to be honest, I only had the patience to do this:

Well, friends, this is how, it would seem easy, we made an acoustic screen for recording voice on a computer.

But this method of making a screen has both its pros and cons. Pros:

  1. It cost us little
  2. Functionally, it is no worse than the purchased one - it copes with its task.

But he has his drawbacks, and I'll tell you about them! Minuses:

Well, by the way, here is the result of my work:

My conclusions: if I had to make an acoustic screen again, then I would still spend money on buying acoustic foam rubber: in the end, paint is not taken, and we save time significantly. With his help, I would not make a screen for a month, but only one or two evenings.

So think about it before you start self-manufacturing acoustic screen with your own hands!

Oh yeah, and here is the promised video, from where I ripped off the idea:

How long did it take a person to do this?

Well, I have everything. Write if something is not clear in the comments below. I wish you success!

Your Victoria Senokosova

For today I have everything. Develop, create and may success overtake you!

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. Especially often it is found 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.

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 reduce 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.

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 flow, 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:

Foam rubber, known in the scientific world under the name - very amazing and interesting material, 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 rubber 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.
