Noise isolation in the car - the dream of many drivers. Especially when sent over long distances. The noise in the cabin a negative impact on security, because the driver gets tired more quickly and reduces alertness. The car is a combination of many components and units. It sealed the set of all parts, spare parts and equipment, some of which reproduce the technical noise and vibration. This problem is especially familiar to those who have to travel in cars produced in Russia or supported import cars. Most often, in this segment, since the plant is weak insulation cars. Needless to say, than the class of vehicle is higher, the better quality insulation interior car, because manufacturers initially concerned about the future quiet car. But what about the rest of the drivers who desperately move the machines to lower class and less expensive. Need more insulation of the car. What should be done to eliminate the noise and vibration in the cabin? Where does the noise? Birth of the noise includes a variety of sources, which figuratively divided into: primary and secondary. The nodes of transmission and the engine, tires, rain, wind, other cars, a bad road - are the primary sources of noise. Elements of interior and body elements - secondary. Noise appears on the stage - especially primary noise, the sound waves are born, they also transmit the noise of secondary sources, therefore we feel the noise in the cabin. "The weak resistance to external noise" affects those machines, elements of which are not treated with appropriate noise-canceling trains. The main ways to reduce and protect against noise: 1. Reducing squeak. It will be useful to remove the squeak caused by the "festivities" of metal panels of the car and / or its individual components during the trip. In the car bigger than the other decorative elements creaking doors and trunk, Torpedo. To get rid of squeaks apply the necessary porous sheets, which can reduce noise. Proofing material unique in that it does not skip the water and consists of "closed cells". Based on this particular squeak disappears. Noise isolation will kill a lot of man-hours and perseverance in order to carefully glue all the necessary surface in the car. The noise from under the hood suppress through special heat-resistant label elements, including heat-layer. 2. Suppression of vibration. The absorption of noise, born out of the vibration of those or other mechanisms (nodes, elements). To avoid vibration bonded to flexible self-adhesive materials, manufactured on the basis of bitumen resins. Basis of action - to change the mechanical vibration energy into heat. Sheets vibromateriala meet with a thickness of 2 to 6 mm, often involve more and thicker pieces of 10 to 15 mm. Suppose you plan to deliver high-quality acoustics for listening to music inside the machine, it is necessary vibroobrabotka. 3. Soundproofing of the car. Involves a full range of measures to suppress noise, squeaks and vibrations. You can try on their own to cope with noise and vibration, spending their time and spend enough effort. Yet, many times more reliable and easier to go to the closest tuning center, which perform such services as car noise insulation. Only in this case, you will hear a full information professional, to the same guarantee for the functionality of the work performed. Get a vehicle generally quiet - it is impossible. But subtract the peak noise stimuli did not prove a problem.
