Life hack - do-it-yourself soundproofing of a Priora car

The standard sound insulation of the Priora car leaves much to be desired. Car enthusiasts strive to correct this deficiency with their own hands, since extraneous sounds irritate and distract the Lada Priora while driving.

They make noise on the doors, floor, arches, ceiling, engine compartment, hood, trunk, panels, dashboard - after this the Priora becomes a quiet car. The source of extraneous sounds can be a malfunction of the engine, its components, malfunction of suspension parts, brake system, steering, etc. Unpleasant sounds occur when driving on gravel roads due to vehicles passing by, especially heavy vehicles. To get rid of unpleasant sensations, it is necessary to modify the standard sound insulation. You can do this yourself. Depending on the body type: hatchback, sedan, or station wagon, the Shumka technology is slightly different. Read the article to the end and we will tell you how to do it correctly!

It is necessary to purchase materials and acquire tools in advance.

How to soundproof doors

To perform soundproofing of Lada car doors, you need to remove the handles and trim material. Eliminate the stock version. Then clean the surface from dirt and degrease. Before use, warm up with a hair dryer. It is applied to the surface in separate elements. Make sure all wires fit freely into the holes. Next, you can apply vibration insulation and sealant to them. A noise absorber must be placed on top. Glue anti-creaking on the border of the material. Reinstall the trim and handles. Start soundproofing the Priors from the front doors, then the rear ones. The anti-corrosion coating should not be damaged.

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 noise occurs because the fuel mixture explodes in the combustion chamber, releasing gases that then exit into the exhaust pipe. We will not talk in detail about the operation of the engine, you can read about this in another article, but here we will talk specifically about how to muffle the exhaust sound.

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.

First layer of vibration isolation

It is necessary to prepare the surface. Determine the required sheet size. The larger it is, the fewer joints you will end up with. Before use, the material is heated with a construction hair dryer on the side where it is treated with bitumen. Then the layer is applied to the base, fixed and straightened using a roller. To obtain a better result, it is recommended to use another layer. Lay it out overlapping. Depending on the quality of the chosen substance, the area that needs to be covered depends. On average it is 50-100%.

Reviews after soundproofing the floor

Results before and after soundproofing the floor on a Lada Vesta:

Recently, the results of complete sound insulation of the Lada Vesta sedan were published. As a result of the work done, the noise in the car interior was reduced by 1.5 dB (according to material manufacturers, the difference is 2-4 dB ). You can imagine what the effect will be just from treating the floor.

What reviews can you leave about floor soundproofing? What scheme is best to follow when performing work?

Roof

The roof and hood of the Lada Priora are the easiest elements to start working with. The standard sound insulation of the ceiling of a Lada Priora car consists only of upholstery. The work begins with preparing the base by dismantling the factory cladding. One can be removed through the rear door or through the luggage compartment. The adjacent plastic covers are also removed. The surface is cleaned of dirt, dust, and treated with a solvent or degreaser. Allow the surface to dry. Prepare a piece of insulating material of the required length, a hair dryer, a knife, and a roller. Try to minimize the number of segments. Preheat the sheets with a hairdryer. When the surface warms up and becomes sticky, fix it on the ceiling. Roll with a roller. Next, apply a layer of material that absorbs sound waves. Splen is most often used. It retains heat well and has an adhesive backing. It is not difficult to fix it on the ceiling of the priors. Splen is applied to the entire surface. To consolidate the insulating effect, you can supplement the cladding with a layer of bitoplast.

After finishing, the upholstery is installed in the reverse order. Keep in mind that the thickness of the layers of noise-absorbing material of the Prior should not be too bulky. Otherwise, the bolt holes for the passenger handles will not line up. In general, for a prior you will need 2 sheets of splen, 2-3 sheets of bitoplast, 2.5-3 sheets of insulating material.

Lada Priora is completely soundproofed.

Lada Priora. Complete sound insulation. Option Maximum.

More than a dozen cars of this model have passed through our hands, and before the car arrives, we prepare soundproofing material in advance and put it to warm up, which significantly increases not so much the speed of work, but the quality! We are ready to work, the tools and gloves are clean and we are starting full noise insulation.

Roof. We dismantle the ceiling using clean tools. After dismantling all the ceiling supports, the ceiling itself is removed and work on the metal begins. Warm vibration insulation Shumoff M3 is glued over the entire area of ​​the car ceiling and rolled out with special metal rollers. Already at this stage, tapping on the roof from outside is accompanied by a dull sound, and not a ringing sound, as before.

The thick noise insulator Shumoff P8V is also an excellent heat insulator; we also use it to seal all vibration insulation.

The last layer is a powerful sound absorber Germeton A15, it will bring noise insulation to the maximum.

Doors. Disassembling Priora door trims is not a difficult task for us and takes our team about 5 minutes. Then the metal is degreased and dried. We cover the outer wall of the door with Shumoff M3 vibration insulation and carefully roll it to the metal with rollers, ensuring that vibrations are removed from it.

The next layer is the Shumoff P8V sound insulator with a waterproof adhesive base, which protects the material from environmental aggression (moisture, dust, dirt in the door). This material holds even better on a vertical surface and is guaranteed not to fall off.

Let's move on to the inner frame of the door, which also needs vibration isolation. We do this with Shumoff M2 material.

The picture is completed by a layer of sound absorber Germeton A15.

Floor, trunk, arches. Car soundproofing in Omsk is widespread and there are many installation points where this can be done. But we set ourselves apart from the rest by achieving maximum results by installing thick, expensive and efficient materials. We can best demonstrate this on the floor and arches of the car. While most studios diligently treat the floors and arches with M2 vibration insulation, we use the best of all vibration insulation, Shumoff Mix F. And we do this on every car, be it a small hatchback or a huge SUV.

The floor above the feet of the front passengers is one of the most critical areas. We try to climb as high as possible onto the engine shield. If the client wishes, we can remove the dashboard and treat the engine shield even more (and at the same time we will soundproof the dashboard). This service comes at an additional cost.

Now it’s the turn of sound insulation and again we try to do our job as efficiently as possible by laying thick Shumoff P8V sound insulator on the trunk and floor.

The last layer is to lay Germeton A15 on the floor and arches.

Assembly of the interior begins. We guarantee build quality that meets factory standards. The interior of the car is assembled in its original form. All panels are installed in place in accordance with factory requirements. We do not break the casings and pistons during the work, so after completion you will not notice any traces of presence in the car. We wipe down the interior and the car is ready for delivery. The soundproofing of the car is complete. 3 qualified craftsmen worked on the Priora and completed the job in 12 hours.

Soundproofing stages

The front and rear row of seats are removed. The central tunnel is being removed. Remove plastic trim and floor covering. Clean the surface from dirt and treat the interior with solvent. The first layer is a heated vibration-isolating layer. Roll over the top. The next layer of material is overlapped. Instead of this material, mastic made from bitumen is suitable. There is no need to cover technical recesses in the floor. Application of splen or bitoplast. They are applied to the entire surface of the floor by priors. To avoid rattling, it is recommended to weigh down plastic elements with pieces of noise-absorbing composition. Cover the joint area with anti-squeak. Install factory sound insulation on the Prior floor.

Correct soundproofing of a car floor with your own hands

The main source of extraneous noise in the car interior is the wheels, so special attention should be paid to soundproofing the floor. Currently, there are several schemes for its installation. Let's look at the most popular installation methods and determine which scheme is better.

Is floor soundproofing necessary? This modification will reduce the noise level from the wheels, transmission, engine and suspension. Efficiency directly depends on the chosen installation scheme and materials.

Trunk

Particularly relevant for Priora hatchbacks and station wagons. Soundproofing the trunk begins with removing the flooring of the interior space and the trunk lid. The surface of the body is cleaned, washed, treated with a degreaser and solvent. Soundproofing of the Lada Priora trunk is carried out according to the standard scheme. A vibration-insulating base is applied in two layers, which is preheated to a sticky state. Then splen and bitoplast are laid. The layers are rolled with a roller.

It is especially important to perform high-quality sound insulation of the luggage compartment arches. It is worth paying attention to plastic elements. The holes must be left open. The wires are insulated with anti-creaking, and the plastic parts are made heavier.

Sound insulation of the engine compartment of the Lada Priora

— the front instrument panel is removed;

— we also remove the factory insulation;

— use a photograph to record the position of all wires and bearings;

— wash the surface, clean it with sandpaper, treat it with a solvent;

— heat the first layer of the vibration isolator to a sticky state and fix it;

- rolled out with a roller;

- second layer - splen, bitoplast;

— insulate the wires with anti-squeak;

- Reassemble the panel in reverse order.

Sound insulation of the hood

In addition to the standard set of materials and tools, you will need factory insulation with clamps. Clean the surface, treat with solvent, and dry. The first vibration-isolating layer, preheated. Roll it out with a roller, then lay the splen. The next layer is standard insulation.

Lada Priora is not a good Shumka. This is easy to fix on your own. The procedure will not take much time and money - if you do it yourself, it will take a couple of weeks and 5 thousand materials. If you do it in a hotel, the price will be from 25,000 rubles.

How to make the quietest muffler for a car yourself?

When the issue with noise during car operation has gone too far, and you have decided to make the quietest muffler for the car, then you need to start by preparing the tool. We will need:

• welding machine, an inverter or semi-automatic will do;
• angle grinder and discs for it;
• workbench with a vice.

The surest and most inexpensive way to make a muffler quieter is to weld in an additional resonator. This can be done in a garage yourself.

An additional resonator can be placed between the standard resonator and the muffler. You can install a ready-made resonator; you just need to weld it into the desired place in the pipe. Or you can assemble the resonator yourself. For those who doubt whether the exhaust will become quieter if an additional resonator is welded in, the answer is clear - the exhaust will become quieter. If everything is done correctly.

Required tools:

1. blowtorch or household hair dryer;
2. bimast super (5 sheets);
3. bimast bombs (1 sheet);
4. bitoplast 0.3 sheets;
5. splen 2mm (0.5 sheet);
6. splen 8mm (2 sheets);
7. White Spirit.

First of all, remove the seats and several parts of the interior. On a Priora, removing the center console will require a lot of time.

1. Clear the floor and remove all rugs.
