Noise isolation with his hands on the example of the VAZ-2108

Noise isolation with his hands on the example of the VAZ-2108 Some theory Despite the fact that the description of the various installations of insulation, usually mentioned in passing, in reality it is very important, and disparagingly refer to it simply impossible. Listen to good sound through a lot of outside noise from engine, road and other stimuli, no one wants. The sad fact - for domestic cars is particularly relevant. Moreover, the traditional noise added to the noise source which will own a stereo system. It creates vibrations of the air, especially the powerful waves from a subwoofer, lead to the fact that they begin to "vote" paneling and other interior elements, including body panels. Noise and vibration also aims to create a Speakers & Subwoofers optimal working conditions, as the installation of LF and LF / MF-heads in jarring mounting surface without complying with integrity will lead to disastrous results: the panel will make a noise from vibration, but about good Bass can be forgotten. Even if the requirements of tightness (ie the absence between the speaker and the mounting surface of any gaps through which air could leak), shaky mounting surface will result in poor bass, for instead of being set in motion the air masses, the speaker will vibrate itself . Materials used: 14 sheets of Vibroplast M2 size 0.6 x 0, 9 am The solvent grade 646 (1L). Required Tools: knife (better shoe), a spatula, mortar hair dryer (heat gun), a set of screwdrivers (preferably cordless screwdriver with a set of nozzles). The first thing we need to do is completely disassemble the vehicle. That is, remove the skin from the doors and roof lining sidewalls of the rear seats and rear wheel arches. No specific recommendations here, the only - you need to act carefully. For example, when removing the door casing fastening plastic caps have a tendency to break, although in our case and the penny costs. Of the tools only need a screwdriver crusades of various calibers. Second - this is the dismantling of the factory lining, which in our Eight does not hold water because of low efficiency. To do this, your regular spatula, and to facilitate the process of building a hairdryer. Sound-absorbing material located at the bottom of the cabin, it was decided to leave because he is quite satisfied the requirements. Once all the surface for subsequent processing cleaned, they must be thoroughly degreased. For this we need a solvent (photo 2). In our case the situation is complicated by the fact that the body drafting the VAZ-2108 was processed by the previous owner of corrosion-resistant material Rust Stop, which had to be removed in the field of sizing noise insulation sheet, as they to him very badly stuck. The next stage after the end of the preparatory work - sticking soundproofing, and in this case, you must act on the principle cereal butter will not spoil. That is our task - the maximum process all the selected surface. We start with the doors. Cut pieces of material, with sticky sides remove the protective layer and paste first inner cavity, up to the rope to open the door. The process itself is somewhat similar to wallpapering: start with one hand while carefully smoothed. For those who first perform this procedure, we recommend you cut Vibroplast M2 smaller chunks. The outer door panel hang completely, and do it in order to create virtually closed volume, which will run the front speakers. Here we already operate with entire leaves. Hole in the place to mount speaker to do immediately, it will be used for wiring and other preparatory work of the second and the easiest step - processing the roof interior. Here are acting on the same principle as with the doors last in our work - the luggage compartment. Since the surface of the arch have a complex shape, for a tight bond to make diagonal cuts, taking care not to damage the paint. Then on the same principle hang all internal and external surfaces of sides, including the middle and rear rack.
