What is required for car noise isolation and how to do it
It's nice to go in the car and enjoy the silence. Of course, it is impossible to achieve complete absence of sounds, but it is necessary to strive for this.
Silence is one of the components of comfort
Nowadays there are many companies specializing inon the most different types of tuning, in particular, and on the noise insulation of the car. These enterprises give a full guarantee of the quality of work and reliability of the materials used and are even ready to measure the sound level in decibels, as they say, before and after. Owners of expensive and prestigious models, perhaps, should be addressed specifically to them, especially if there is no shortage of funds.
But for those who travel on second-hand foreign cars or"Zhiguli", it is worth thinking about how to make noise isolation of the car with your own hands. The fee for the services of specialized workshops may seem excessive, it is sometimes commensurate with the cost of the entire machine.
A normal man, not deprived of diligence and able to handle tools, can do this work himself.
Where does the noise in the cabin come from?
Getting to work on installing sound insulationcar or even thinking about this issue, you need to immediately imagine what you have to fight. Sources of buzzing, rattling, whistling, tarahtenya and other such unpleasant sounds are inside the body, but it is not out of place to take into account external sounds, which also want to fence off.
So, the main cause of discomfort may well bebe engine. But the effects of prolonged exploitation, expressed in the mutual movement of the individual elements of the construction, can also be no less irritating, in other words, the looseness. Screws no longer firmly hold what they need to fasten firmly, somewhere there are unnecessary backlashes, and the skin in some places vibrates against the metal, making plaintive moans.
Down with all the excess
Begin the process of noise insulation of the car shouldwith a rather laborious operation. From the salon you need to extract everything that is in it, leaving in an ideal only metal surfaces. But do not show too much zeal, because if you set a goal to remove everything, then you can overdo it and then worry for a long time about where to get the broken brackets and mounts.
The main thing is to remove the floor covering, the seats and the lining,including the door. At the same time it's a good idea to fix all the wires: they will not be able to crawl over the metal during the ride, which means they make noise and will last much longer. Having investigated the skeleton of its "iron friend", it is possible to find foci of rust and treat them with a modifier. It goes without saying that all surfaces must be clean, and the threaded connections are subjected to revision and pulling.
What will be required
Materials for car noise insulation todayare completely accessible. They can be selected by consulting with the seller in advance and purchasing the appropriate ones. It will take two types of self-adhesive layers. At first, the visomate is applied, and on top of it is stylosol. However, the names may be different, the choice is great.
The main quality, which allows to suppress vibrations andexternal sounds, is the porous structure of the material. The more dense it is, the better the effect will be. To avoid the appearance of bubbles, a roller is useful, and for adjusting the size you need a sharp knife.
And now for work
Now everything is simple, the goals are clear, the tasks are defined. You can start from the roof or from the bottom, it's like anyone. All technological holes, not necessary for the operation of mechanisms, but serving as acoustic conductors, it is better to seal with reinforced tape. The entire process of noise insulation of the car can be done in a few hours, it's quite easy. More time will be spent installing all the removed parts and coatings in their places.
Having finished with the salon, you need to engage in motorcompartment, especially the hood cover. It is already equipped from the inside with a special coating, which should be temporarily removed and glued sound absorbing layers. In addition, in some cases a special porous heat-resistant layer is applied to the cylinder block cover, which quenches the oscillations, and the motor runs much quieter.
