Shumoff: How much and what materials are used in car noise insulation?

Shumoff, the master of noise-vibration isolation, will help you to find out how much what kind of materials you need to completely isolate a car from extraneous noise and vibrations.

Shumoff-noise vibration insulation materials, most of which have no analogues on the market. By painstaking work of diverse specialists over the idea of ​​developing a high-quality product, vibration absorbers Shumoff (Shumoff) were created. They combine numerous vibroacoustic studies, continuous improvements and special attention to the requirements of consumers. The material features of Shumoff are: convenient size of materials, unique embossing pattern, durability and high damping characteristics.

In this series of articles, car owners will be able to find out how much and what kind of materials Shumoff is needed for sound insulation of the three main types of cars.

Almost every car is still in the factory undergoing a process of sound insulation. You can see and evaluate its condition, as well as the amount of additional noise insulation required by removing the interior of the car. Therefore, before proceeding with the process of noise isolation, it is necessary to identify areas of increased noise in the car. You can do it yourself by listening to the sounds while driving a car, or with the help of a workshop technician who can help you find the source of noise of "unknown origin." The result of this testing will be your decision on the full or partial for sound insulation of the vehicle , because you know that annoys more-the noise of the rain on the roof, the noise of the engine or the creaking inside the car, and perhaps all the noises listed interfere with "listening to music".

Full insulation of the car includes the treatment of the roof, doors, hood, floor (bottom), luggage compartment (luggage cover), torpedoes, engine shield and bulk plastic parts of the interior of the car. Partial noise insulation of the car-isolation of individual problem areas, often using less material. As a rule, these are the rear arches of the car wheels, the boot floor, the roof and the doors. The necessary minimum-insulation of doors and roof, allows you to improve the sound of even standard acoustics, not to mention an advanced music system.

For sound insulation, an integrated approach is needed, involving the use of both vibration and noise insulation materials, as well as materials used at the joints of plastic parts (antiskrip).

Vibration insulation materials are a bitumen layer of different thickness with foil-coated and adhesive base. They are glued to pre-prepared metal elements of the body, increasing the weight and rigidity, thereby reducing the resonant frequency of noise. The second layer is applied noise insulation materials that absorb noise and perform the function of thermal insulation. Using only soundproofing materials will give "some result", but the costs most likely will not be repaid.

It is also necessary to understand that it is impossible to completely get rid of the noise in the car. If the body itself can be soundproofed, then constructive noise (noisy engine, thin metal, imperfect engine mounts and vehicle exhaust mounting systems) can be dealt with only at the design stage of the car, but with the help of vibration and noise insulating materials it is possible to reduce the noise level. With delivery in Ukraine, noise insulation can be bought in Kiev, Kharkov, Odessa on 130.com.ua.

It is easy to calculate the material for sound insulation of a car, knowing the processing area and the sizes of sheets of selected materials. When calculating it is necessary to take into account that more material leaves on bends. Vibration insulation of the entire surface of the metal can not be done. For example, on the roof it is enough to paste over the area between the stiffeners. Another thing is noise insulation cabin bottoms, which should cover 100% of the surface and overlap at the joints or butt-butt. In the process, you should not forget about the "overload" of cars overweight noise insulation, including in order to avoid bending the hood or trunk lid.

You can use ready-made solutions of specialists and buy a set of car noise insulation, containing vibration and noise insulation materials for sound insulation of individual elements of the car (doors, rear arches, trunk ...). Installing additional noise isolation yourself, carefully examine the state of the regular-in places where it departs, it makes no sense to apply the second layer, it is better to remove it and install a new one.

To achieve maximum effect, save time and money, professionals recommend making full noise insulation in one go. The fact is that the cost of installing noise insulation includes the work of assembling and disassembling the necessary parts of the car. In the SRT, this complex and time-consuming process takes an average of 5 working days (for a middle class car). Qualitatively performed work by specialists will cost about 40-50 percent of the cost of the material. With full noise isolation, including a complex procedure for disassembly and especially the assembly of the cabin, the cost of work can increase to 90-100 percent. Since this process requires maximum accuracy and the use of special tools (for example, it is almost impossible to remove a torpedo by yourself), the conditions of a service station should be assessed (at least visually). Another caveat-be sure to negotiate with the SRT the stages and deadlines for the work, the provision of a phased photo report on the work done.

Specialists Shumoff have developed a special line of materials that are effective, comfortable in storage and transportation, and can be mounted on cars without special equipment and skills. Recommendations of experts on the use of these materials for cars-small, middle class and SUVs will help to achieve maximum effect without extra cash.
