5.Results: sound insulation of doors in the interior of a Lada Priora car in the “Gold” configuration at a price of 29 thousand rubles

The car was brought in with complaints about extraneous noises in the VAZ hatchback, which greatly irritated him, as well as an unpleasant clanging sound when the doors slammed. The car owner was satisfied with the complete sound insulation of the Priora at the “Gold” tariff. Additionally, he asked for a dashboard wrap and asked how much it cost. Answer - the service is not included in the price and is paid separately.

Full sound insulation Priora in Moscow - cost

How much does it cost to install complete noise protection for the VAZ Lada Priora hatchback in our studio in Moscow, using the best materials? To achieve the effect, we offer three configuration options for soundproofing the vase. The price of the service depends on the preferred option. Tariffs vary depending on the quality of materials and the amount of work performed on the vase. It is distinguished by the use of denser materials and a more powerful effect. Unlike the most expensive “platinum” option, its cost does not include additional sound insulation of the internal arches, doors, door trim, rear parcel shelf, floor, and trunk of the Lada Priora. Therefore, the latter tariff is more expensive in cost, at least 6 thousand rubles. “Silver” differs from Golda in that the cost of the service does not include car fender liners and outer wheel arches.

Rules for applying sound insulation

The instructions for applying sound insulation are the same, no matter what kind of car you treat:

Preparing the surface for processing begins with removing the casing, factory sound insulation and anything that will interfere with your work.
Then, the surface must be washed, if there is rust, clean it and prime it
After this, you need to degrease the surface
Now you can cut out the vibration material, it is always placed first, remove the protective film, heat it with a hairdryer, apply it and roll it with a roller to expel air bubbles
Vibromaterial is placed overlapping, so the protection will be more effective
A noise absorber or a noise reflector is glued on top of the vibration insulation, it all depends on the place of treatment
It is self-adhesive, sticks in sheets on all 100 percent of the surface, it does not require heating (vibrating material is enough to stick on 80-90 percent of the entire area)
Anti-squeak materials are glued in places where the skin comes into contact with the metal, and in places where the skin elements come into contact, around the handles

Roof treatment

It is recommended, especially for beginners, to start from the ceiling or hood, where gluing is much easier:

Soundproofing a Priora roof begins with removing the sheathing
Then wash and degrease the surface, after which vibration insulation is applied

The nuances here will be as follows:

It’s more convenient to glue with an assistant so that he warms up and feeds the pieces, then holds while you roll the material to the roof
The thickness of the vibration absorber on the roof should be 2-3 millimeters, and the thickness of the sound absorber - 5 millimeters, otherwise it may bend from the weight

Priora roof vibration isolation

After soundproofing, return the roof sheathing to its place

Hood

Hood processing nuances:

Vibration insulation is placed only in the recesses (photo below), covering the whole thing is just a waste of material and time, you won’t notice the effect
But the sound-reflecting material is glued in one piece to the entire surface, it will also serve as insulation
A material with a foil layer is recommended for the hood, as this will protect it from the effects of temperature

This is how the vibration insulation is glued to the hood, there is no need to glue it anymore

Under the hood there is a partition between the engine and the passenger compartment (engine shield), it is treated with vibration isolation, then with a sound deflector, through it the hum and vibrations from the engine are transmitted to the passenger compartment, so its treatment cannot be skipped

Salon

Sound insulation of the trunk of a Priora hatchback is carried out in conjunction with interior treatment, for this:

All rugs and chairs are removed, as well as all floor coverings.
If there is any semblance of sound insulation, remove it and throw it away.

The interior is treated at the same time as the trunk

Then, wash the surfaces, the floor of the cabin is the most contaminated place
Don't forget to degrease the surface
Here, a minimum 5mm vibration absorber is used, and a 10mm sound absorber is placed

Priora hatchback trunk soundproofing has one nuance; the niche for the spare wheel should be glued with thinner materials, otherwise the wheel may not fit back in
Wheel arches, front and rear, are glued with a double layer of vibration insulation

Doors

Doors are treated in three layers:

The first layer of vibration insulation is placed on the door panel, inserted in small pieces through the technological holes, and glued overlapping

Vibration insulation treatment of door panels

With the second layer, the outer surface is treated with vibration insulation, while all technological holes are sealed to create a closed box for the speakers

We close the technological holes to create a closed box

Glue the sound absorber as the third layer
You can additionally glue the door trim with a sound absorber from the inside
Places where the trim comes into contact with the metal of the door are glued with Madeleine, and also Madeleine is glued around the door handles so that squeaks disappear

Task: installing sound insulation for a Lada Priora car in the “Gold” configuration

The first thing we decided to do for complete sound insulation was to cover the roof of the VAZ car. We carefully remove all unnecessary elements from the roof, including the sheathing on the roof of the vase. Now you can make the first layer of sound insulation on the car ceiling. We install a high-quality damper from SGM Alumast Alfa to neutralize vibration on the vase roof. How much work does this cost us? You yourself can guess by the appearance of the roof in the photo and the effect achieved. The roof of the Lada Priora is not only protected from vibrations, but has also become stiffer. The use of vibration on the roof significantly reduces the overall sound background in a hatchback car. Then you need to make another layer on the roof. For this purpose we use a thick layer of Violon WELL sound insulator. It eliminates unwanted sounds. After installing it, it is almost impossible to push through the roof of the car, and raindrops will definitely not cause any discomfort to anyone. After assembling the upper part of the interior and hatchback of the car, all we have to do is take on the lower part to achieve a similar effect.

Sound insulation of LADA Priora doors

Soundproofing or soundproofing of the VAZ 2170 is often done for one simple reason: since the car is Russian-assembled, it is not famous for its quiet interior and silent ride. In addition, one of the main sources of noise is the noise from the wheels when driving, so the issue of sound insulation of Priora doors is currently the most pressing. The technological process of sound insulation is almost the same regardless of the make and type of car. But each individual case has its own subtleties and nuances.

Soundproofing Priora doors begins, first of all, with removing the upholstery material from the doors. Under the upholstery there is standard sound insulation, which must be carefully removed. After this, you should thoroughly wipe the metal door frame, for example, with White Spirit, degreasing and cleaning the surface. It is worth noting that the anticorrosive agent located at the bottom of the doors must under no circumstances be removed!

The most optimal and simplest option for installing sound insulation is considered to be the option in which sound insulation is made using layers. Soundproofing Priora doors with your own hands of this type will take you no more than 10 hours of work. You will also need about 7 sheets of vibration-absorbing material, 4 sheets of Splen, 3 sheets of bitoplast and the same amount of modelin.

The first layer of sound insulation of Priora front doors is the installation of vibration-proofing material inside them:

First, you need to cut out several sheets of suitable shape and size from the vibrating material (the larger the sheets, the better).
Next, using a technical hair dryer, you need to heat the bitumen side of the resulting sheets.
Then heated pieces of vibration insulation should be glued to the inside of each door and rolled out with a hard iron or plastic roller over its entire area.
Then the next sheet is taken and overlapped over the first one according to the algorithm described above.

The coverage of vibration-proofing material on the inside of the doors depends on the material itself, so its percentage (percentage of coverage) can vary from 55 to 100%.

The next layer of sound insulation for Priora doors means sticking sound-absorbing and heat-insulating materials onto the vibration-proofing layer. Experts recommend using materials such as Splen or Accent at this stage. They have a self-adhesive base, so their installation does not require any specific skills or a lot of time. In this case, the entire surface (100%) of the inside of the doors is covered.

A third layer of sound insulation can be installed upon request. The essence of this layer is to cover all technological holes in the doors with vibration-isolating material or the like. If you make a third soundproofing layer, then in case of repair of the window regulators it will need to be dismantled. As practice shows, sound insulation of doors made in three layers is considered the most effective.

Discomfort inside the car when driving also occurs due to squeaks. Therefore, an equally important step in soundproofing doors is soundproofing the door skins. To do this, the upholstery material is first made heavier with vibration material, so it will vibrate less and make fewer squeaks. And then bitoplast (sound-absorbing material) or modelin is glued on top of the vibration material in the places of their contact.

The rear doors of the Priora are soundproofed in the same way. Then the door is assembled in the opposite sequence. It is recommended to use new clips for door trim.

It is worth paying attention to the fact that high-quality sound insulation implies a set of measures that are aimed not only at eliminating external noise from the wind, wheels and road, but also at minimizing crickets and squeaks inside the car dealership. Only in this case will the driver be able to achieve absolute silence and comfort when moving in the car.

Vibration insulation of the floor, trunk and rear arches of the Lada Priora photo

Now we disassemble, thoroughly clean and degrease all surfaces on the floor in the cabin, after which we install noise and vibration insulation on the floor, trunk and arches. How many layers will be required for this installation? This tariff involves installing Shumka on the floor and arches in the cabin in two layers. At the first level, we lay the material on the floor of the Lada Priora hatchback that we have been working with for a long time and successfully. The properties of Alumast Alfa are worth talking about separately. It is plastic and fits tightly to the floor of the car hatchback. That's why we roll it everywhere, even in the most problematic places on the car floor. On top of it we install another layer of insulation. The most suitable material for this purpose, Bibiton, is laid on top of the vibration on the floor. It is worth saying about it that it is a special foam rubber impregnated with polymers and mastic. On the mounting side it has silicone protection. It absorbs as much airborne noise penetrating through the arches and floor of the car as possible. It has high anti-corrosion characteristics, so the car is now protected from rust. This equipment does not require additional sound insulation inside the interior and hatchback of the Lada Priora. The next step will be to cover the arches and trunk of the Lada Priora. Carefully disassemble the lower part of the hatchback car to get to the arches. Then we wipe and degrease the surfaces of the arches. To dampen the arch, we use the same Alyumast, which does not put extra weight on the trunk and arches of the car. We cover the arches and trunk with another layer of Shumka, for which we use an adhesive-based vialon. The arches and trunk should be well worked on to make the interior of the vase almost silent. For the arches here we did everything we could, and we also covered the niche for the spare tire with Uniton. Now the arches and trunk are completely protected from fungus. And visually, as can be seen in the photo, the arches are in harmony with the trunk. We cover the trunk lid of the vase in the same way as the hood. How the materials are cut can also be seen in the photo.

Reviews

After soundproofing the panel, a decrease in motor noise was noted, as well as a complete absence of squeaks and rattles inside the panel. The difference in dB before and after the ShVI dashboard can be observed on the graph:

To reduce the noise level in the cabin by 2-4 dB (a difference of 1 dB is barely noticeable or not noticeable at all), it is necessary to take a comprehensive approach to car sound insulation, work on all parts of the body (floor, doors, roof, trunk, etc.). ), wheel arches and fender liners. Also, on LADA cars it would be a good idea to install additional door seals (instructions for XRAY, Vesta, Granta/Kalina/Priora, Largus and Lada 4x4).

What feedback can you leave about the soundproofing of the panel? Is it worth removing the dashboard to do this kind of work?

Ways to muffle the exhaust sound

Before tuning the exhaust system, you need to understand the reasons why the sound of the engine becomes louder over time. The operation of the engine itself is a fairly loud process, but the muffler and other components of the exhaust system perfectly suppress this loud noise. Without a muffler, the engine noise is very loud.

The explosion releases energy that pushes the piston, and when the piston has moved the required distance, the exhaust valve opens, through which the exhaust gases exit and go further through the exhaust system. To effectively absorb noise, thick metal parts are used. So, the thicker the metal used in the exhaust system, the quieter the car will drive due to the fact that there will be less vibration.

The exhaust manifold is the first one to absorb the noise, which is why it is made so large and thick, so it best dampens the noise that comes from the cylinder block. Even if you compare the exhaust pipe of any more or less normal foreign car with the exhaust pipe of a domestic car, you can see that in foreign cars the pipe is heavier and thicker, which is why such a car runs quieter.

This is why when you drive an old VAZ 2114, the noise is such that you can’t hear what the passengers in the rear seats are saying, which is why you start thinking about how to muffle the exhaust sound.

The exhaust system also has a resonator, which is needed to reduce the speed of gases through the exhaust pipe. And after the resonator comes a muffler. When exhaust gases pass through the resonator, they lose some energy and continue to flow more slowly.

Gases lose the largest share of their energy in the muffler. If we consider a good muffler, then it contains several separate housings, after passing through which little remains of the noise.

How to make noise insulation for a Priora floor with your own hands?

Laying the bottom layer (there are two ways):

For laying the bottom layer, sheet vibration-insulating material is often used. First, you need to cut the sheets to the required size (it is more convenient to work with large sheets), then use an industrial hair dryer to heat the bitumen-coated side of the sheet. The prepared sheet needs to be placed on the floor of the car with the heated side and walked over it with a roller several times, pressing it against the metal bottom. The remaining sheets must be installed in the same way, laying them overlapping. The manufacturer, in the instructions for the vibration isolator, indicates how much surface area needs to be covered with this material.

Nuances when carrying out soundproofing of the floor priors:

It is recommended to wrap the wires with tape/adhesive tape every 20-30 cm to prevent interference in independent work.
It is recommended to fold bolts and screws according to size.
The rubber roller can be replaced with a hammer, since the surface is not smooth. And the hammer will make it easier to fix the vibration.
The joints of plastic parts with the body, as well as the elements themselves, can be covered with madeleine.
The factory soundproofing layer should be hung and dried.
Application of vibration materials is carried out overlapping or end-to-end. With the first option, you can later trim off the excess with a knife.
To apply vibration to a hard-to-reach surface, it is recommended to cut the material into smaller pieces.

Possible inconveniences associated with a quiet muffler

The car will now be quieter, which is what we wanted to achieve, but there may be some disadvantages - an increase in the overall weight of the exhaust system. Therefore, it is necessary to hang stronger brackets so that the exhaust pipe does not come off on rough roads. There are also cases when rubber shock absorbers are hung. But in fact, a homemade resonator will weigh about 2-3 kg.

It is also necessary to test in action how the exhaust system works so that gases exit normally through the exhaust pipe. Therefore, it is necessary to check at higher speeds, then it will be possible to draw the right conclusions. But as a rule, gases will escape through such a resonator without difficulty.

And then in the video there is another way to reduce the sound of the muffler, making a really very quiet exhaust system:

Problems with the exhaust system send drivers to maintenance. Whatever muffler you install, it will burn out over time - no matter how much it costs. The muffler, also known as the exhaust, of a Priora sedan, hatchback, and station wagon is the same and also burns out over time. Of course, the main muffler on the Priora is better made of stainless steel - despite the fact that it is more expensive. The price for example is STT - 4950 rubles, and Mute stainless steel - 4500 rubles, Stinger (stinger) - 4100 rubles. Replacing a muffler, although not a common thing, car enthusiast forums are regularly updated with fresh articles devoted to the problems of the Lada Priora car exhaust, operation, and replacement of the middle part of the car exhaust system, clearly indicating the relevance of the issue. The exhaust system is the exhalation for a car - it is important, just like the intake system. In this article we have collected most of the most pressing consumer questions.
