Selection and installation of proofing tools for car

Usually problems excessive noise are solved at the stage of designing the car with the help of constructive solutions, selective Assembly, precision machining and other engineering methods. However, they have limitations due to the level of existing technology and development of equipment. Still, the decrease in the acoustic load to some extent can be resolved in private by installing sound insulation. As practice shows, well-organized system of isolation and redemption audio allows you to achieve quite acceptable results. Another condition for this is the correct choice and installation of anti occur during operation of the vehicle noise. This is what goes on it.

Noise isolation of the car - a rational approach

Planning process sound protection vehicles, primarily determine the required scope of work, the type and brand of material used. It should be aware that no matter how You tried, no matter how carefully the scale and don't put insulating materials, to achieve absolute silence You, of course, will not succeed. But to make the conditions of the car, and next to him is acceptable is another matter. The main thing is to not "overdo it", because at a certain stage, additional layers of sound-absorbing products will not give any result, but will only create unnecessary thickness of the coating and increases the cost of the event. Here you need to follow the principle of minimalism and sufficiency.

With all the richness of choice in the market of goods and services to select the optimal set of products not so easy. This question can only be one recommendation - buy the goods for the protection against noise and vibrations is better to have serious operators giving preference to well-known brands and reputable manufacturers. With a limited budget will have to rely on the case. In the diversity of strategies and means of eliminating acoustic shortcomings can be identified three main approaches and methods of solution of this issue. This may be a point impact on the problem area, creating a "lion's share" of the noise field, and can be considered a complex effect on the sources and paths of propagation of sound waves. They are implemented in the form of a standard or a full set of acoustic events. Their difference is only that the first of them proposes to do the insulation on the ceiling and hood.

Preparing to install noise-reducing means

Having defined the scope of work and place of application of their efforts, is set insulation materials. It may contain ready-to-use items, and may require cutting, depending on the individual size and configuration of the protected surfaces. For the cutout of the standard detail sheets the desired shape you can look ready scheme on the Internet (often such searches remain fruitless), but you can make cardboard templates, which have to make individual forms.

First of all, to ensure the installation of noise insulation materials to produce the complete dismantling of the cabin. Usually they are placed in one, two or maximum three layers. Thus, overlap between the main sources of transmission of sound and mechanical vibrations. All work is not necessarily carried out in a specialized box, it is quite suitable for a normal garage. Importantly, do not forget that for good adhesion and reliable installation the ambient temperature should be above 15 degrees Celsius, unwanted humidity.

For disassembly remove the interior trim, plastic panels, decorative elements, overlays. It should be remembered that additional protection is solely under the standard insulation, installed by the manufacturer, so the latter must also be removed. Open thus part of the car body to be processed insulating material, thoroughly cleaned of dirt, rust, lubricants, using any solvent or alcohol. After enduring a few more minutes, you can start the main procedure.

Installation of noise insulation kit

Modern means of noise and vibration and insulation do not require additional fasteners or the application of adhesive composition. The principle of their installation is to remove the adhesive layer on the sticky surface, the installation and fixing of the element in the working position. For easy removal of the protective layer can use an ordinary tape, the very detail of Samothracia need to be fixed progressively from one edge (preferably the upper), carrying parcels to the underlying surface. To remove air bubbles and smooth the surface from the center to the edges of the protective layer.

When performing complex of works on protection against harmful noise factors is necessary to observe the following sequence of operations:

1. Installation of vibration isolation damping layer on the inside of the frame (roof, floor, pillars, doors), pregorodki (the area of the pedals and same area on the passenger side), boot sector. For certain materials require additional heat case with heat gun or hair dryer;
2. Laying polyethylene foam sheets on the dipole part of the body;
3. Handling roof strips with a width of 20 to 30 cm heat and shumoizolyatsionnogo material;
4. Installation of heat and sound insulation on peregorodchatoy plane between the hood and salonnym space;
5. Protection caps, tailgate and bonnet polutoralitrovym layer of silencer based on polyurethane.

For additional resources, noise and vibration control establishes the nominal design of noise protection and are assembled interior trim in reverse order. When you install dashboard and parts of the interior use of sealing materials that prevents rattling and squeaking. They handled all the joints, and is also available in the building ducts.

This scheme, of course, not the only way to ensure acoustic security. In each case it can easily be converted and modified on the basis of available remedies. Online store DD Tuning offers the maximum choice of products that will be of real help in the fight against unwanted noise effects from the operation of the vehicle.
