The VAZ-2107 car is an excellent classic product of the Togliatti Automobile Plant of the past. Despite the fact that it has been discontinued, the 7 remains on wheels for many drivers. Inexpensive and easy to maintain, the device is well suited for getting acquainted with motor transport as the first car for study. But there is a significant downside. Like any Russian-made classic, 2107 has poor sound insulation.

Why is soundproofing necessary, is it so important and how does it work - these and other questions can be answered in this article. Consider the sequence of actions for independent work with your own hands, the necessary tools and materials. And if you have to carry out such a procedure as soundproofing the VAZ-2107, is it worth taking it at all or is it better to give the car to a specialized maintenance center?

Is noise isolation really necessary?

This question can only be asked by owners of foreign cars who have never been to the VAZ-2107. Having once driven behind the wheel or as a passenger of the VAZ seven, you immediately understand that soundproofing is necessary. In the cabin, the sound of the engine, boxes, noise from the wheels and others are clearly audible.sounds outside the car.

Those who like to listen to high-quality sound in the VAZ-2107, in which there is no sound insulation, will be greatly disappointed. Buying expensive musical acoustics will not help. As long as the cabin is not well soundproofed, the music from the speakers will be heavily distorted.

Quality noise isolation brings joy not only to the ears of the owners of the 2107th model. In the cold season, the car will be warmer, and the interior will warm up faster. In hot weather, with proper treatment of the interior in the car, it will be cooler and more comfortable. Many of the advantages of full soundproofing 2107 can only be appreciated live. All questions about the need after that will disappear by themselves.

An easy choice

After the decision to carry out soundproofing is made, it remains to decide where it can be done. There are actually few options:

1) specialized service station;

2) private garage;

3) own hands.

Each individual will have to make a choice regarding where to make the VAZ-2107 soundproofing. Consider the pros and cons of each option. A specialized service will have the largest price tag for work, but a guarantee is possible if something is wrong. In addition, the most qualified work is possible there. A private service is usually much cheaper, but no guarantee. In both cases, it would be good to know if there is a specialist who makes high-quality sound insulation. Ideally, it would be nice to drive a previously made other car for evaluation.

Do-it-yourself soundproofing

So, the only option left is to make everything your ownhands. Is it possible? In fact, everything is possible. But if there is no experience with a screwdriver and wrenches, then this option will not work. For any man, the sound insulation of a VAZ-2107 car is quite a feasible job. The whole complexity of the procedure is not in the actual process itself, but in disassembling and assembling the insides of the car. After all, you need to get to your native soundproofing, and preferably to bare iron.

There are several positive features of DIY work:

• the experience gained is not going anywhere and you don't have to pay for it;
• a good opportunity to get to know your VAZ-2107 closer;
• no time limit - you can work slowly and carefully;
• material savings;
• as a result, you can get a comfortable VAZ-2107, the sound insulation of which is at the proper level, a great deal.

Features of the soundproofing process

In order to produce high-quality sound insulation, first of all, you should understand where the noise comes from, where it is more and what its nature is. It is known that the main sound comes from a running engine and exhaust system. Hence the conclusion: it is necessary to isolate the floor and the front motor bulkhead as much as possible.

Noise that can reach from the street is eliminated by soundproofing the doors and roof. Also, don't forget about the luggage compartment. The noise from the trunk can be very annoying. As a result, it turns out that it is best to soundproof the entire interior completely. This process is also called complete soundproofing. While partialdesignate the soundproofing of a part of the cabin, for example, only the floor.

To understand the processes, it is easiest to turn to physics. After all, both sound and vibration have such a parameter as the frequency of vibrations. And if the vibration is usually low-frequency, then the sound is vice versa. Therefore, it is more difficult to isolate and absorb. This already implies the importance of the thickness of the soundproofing materials.

First steps

Do-it-yourself soundproofing VAZ-2107 is an interesting and exciting process for those who like to tinker with their car. If the work is to be done for the first time, it is necessary to prepare for it. The easiest option is to learn from a master who has been involved in such events for a long time.

Information can also be found in the technical documentation in printed form and in electronic form. Having thoroughly prepared, you can go for the selected material and prepare tools. Sometimes a building hair dryer is required to speed up the process. With its help, the soundproofing material warms up and becomes more plastic. This allows you to press it as tightly as possible to the metal base. A hard roller will be very useful for smoothing coatings.

Materials used

Factory soundproofing VAZ-2107 consists of two layers: anti-vibration and actual soundproofing, often of the simplest quality. For good quality work, these materials can be replaced with improved ones. It is also possible, in addition to these two layers, to add soundproof and anti-creak.

The very first layer protects the cabin from vibrations. The reason for them may be different, but most often it isvibration of the engine transmitted through the supports to the body, as well as the vibration of the gearbox. The worse the pillows of the power unit and gearbox work, the more noticeable it will be felt. Vibration protection material most often consists of two layers: a mastic base and foil. Among the ready-made options are "Vibroplast" and "Bimast".

As for sound insulation specifically, it is known in auto stores as “Shumka”. Physically, it is a porous material such as polyurethane foam or thick felt.

As a soundproofing layer necessary to reflect sound, a material that looks like vibration isolation is used. But its properties are different. Splen can be used as well-known brands. In addition to sound insulation, this material has high thermal insulation qualities.

Modern Shumkov are very comfortable with their adhesive layer. Thanks to him, the installation of coatings is fast and high-quality. Many materials for soundproofing are used universally - both for cars and for the walls of a residential building.

First defense - doors

Despite the fact that the most unpleasant sound enters the cabin through the engine bulkhead and through the floor, it is best to start work from the doors. It's much easier than taking the interior apart. It will take less time, and you will gain a lot of experience. The next steps will therefore go both faster and better.

Start first of all is to remove the skin. Getting toiron base, make a visual inspection for corrosion. If there is one, it is cleaned and treated with a rust converter and anticorrosive agent. Be sure to allow time for drying. Only after that, with the help of a hair dryer, the vibroplast is heated and pressed against the surface with a roller. The next layer is glued soundproofing doors VAZ-2107. And lastly, if there is a desire - a layer of soundproofing.

Car doors contain a lot of moving elements that can cause creaking. Therefore, the use of such anti-creak materials as madeleine or bitoplast is relevant here. The first has a small thickness of about 2 mm, and the second is somewhat similar to thin foam impregnated with a special composition.

Features of noise insulation of doors

Of the important features, it should be noted:

1. It is sufficient to cover only half of the area of the protected surface with vibration isolation material. It has been experimentally established that vibrations are equally well damped starting from half the area.

2. The soundproofing coating will work the better, the thicker its layer.

3. When building up layers of sound insulation, do not forget about increasing the weight of the door so as not to change the hinges later.

Engine compartment soundproofing

The engine compartment bulkhead has a very small surface area. But the time taken to cover it is usually the longest. And this is due, of course, to the amount of dismantling work that needs to be done until the desired surface appears.

A good instrument panel removal guide can be found in repair and replacement resources. After the application of labor, patience and time, the partition of the engine compartment will appear for performing soundproofing work on it. The procedure and procedure for gluing materials is similar to soundproofing doors. The advantage of the partition is that there is no weight limit for it, and therefore, the number of layers. It is important to remember that the layers of noise and sound insulation must be glued without gaps, unlike vibroplast. Sound has a higher frequency than vibration, so a small hole will be enough to penetrate the interior.

Floor and fender protection

VAZ-2107 floor soundproofing occurs in accordance with the general algorithm worked out on the door panels:

• give access to the surface by removing all interfering elements;
• remove factory covers;
• treat the bottom with anticorrosive;
• lay a layer of vibration isolation;
• lay a layer or layers of noise absorber;
• fix sound insulation layer;
• reassemble everything in reverse order.

At this stage, there are practically no difficulties, there are no such works as removing the panel. The hardest part is removing the seats - their weight is the heaviest in the cabin. Again, depending on what to compare. Of the nuances, it should be noted that the VAZ-2107, the sound insulation of which was carried out as much as possible, will be limited during the pedals. Under them, you will have to make a cutout for comfortable driving.

Roof soundproofing

At first glance, soundproofing a car roof might seem like the easiest thing to do. Here, after all, there are no hinged elements, as on the floor, and there are no difficulties with removing the dashboard, as in front. The smooth surface of the roof is deceptive. In fact, there are many nuances for the careful removal of native upholstery and coatings.

Once the bare iron is exposed, a well-established procedure for surface treatment and applying protective coatings will not be difficult. As a result, a truly comfortable VAZ-2107, the sound insulation of which is made by hand, will bring a lot of pleasant sensations. With the protection of the roof should not be "atrocious." No noise in the rain is good, but the layers of sound insulation increase the weight of the car, slightly shifting its center of gravity.

Loud trunk VAZ-2107

The trunk of the car also needs to be covered with soundproofing materials. If you make protection, then make it maximum. In addition, it is in the trunk that a variety of small cargo is most often transported, which specifically makes noise when moving.

VAZ-2107 trunk soundproofing - the procedure is quite simple. It's probably easier just to process the hood. But there's plenty of work here too. There are few even surfaces, like on a roof, so you still have to try.

Hood soundproofing

Good sound insulation of the VAZ-2107 hood is a fairly simple matter. There is enough scraps of vibroplast and a small cut of "Shumka". These works are best done at the very end, eitherdo the very first to "stuff" hands.

If there is native sound insulation on the hood of the car, it should be left. In the absence of it, you can use the thickest soundproofing material. But vibration isolation should be used to a minimum, which means no more than 50% of the surface area. Due to its own weight, vibroplast can significantly weight the lid.

Conclusion

Do-it-yourself soundproofing VAZ-2107 is an interesting and exciting process. The results of the work, in the presence of high-quality materials and the observance of technology, are simply impressive. Of course, it is unlikely that it will be possible to reach the heights of comfort of expensive foreign cars, but the audibility inside the cabin will become close to ideal. You can forget about most external noise and enjoy the new sound of the old speaker system.
