Less noise - more comfort and more time on noise reduction
Few people remember the ZAZ-968 "Zaporozhets", a wonderful peoples car of the Soviet era of the 70s. But then the most popular topics of mass automobile publications were: interior noise insulation and ways to make its unique electric petrol heater work flawlessly in the cold season. In comparison with "Zaporozhets", the salons of all modern cars without exception are just an acoustic room, completely isolated from external noises. But there is no limit to perfection ...
Many are not satisfied with the level of isolation from external noise, which is constructively provided by the manufacturer, especially if they are associated with certain aerodynamic miscalculations and arise in the form of a mournful song when a certain speed is reached. And if there is also a creak, incomprehensible knocks and rattling ... Its not far from stress. And nerve cells, as you know, do not recover. Therefore, every normal owner of a modern passenger car seeks to get rid of these unpleasant sounds in any way. In addition, we have already written more than once about how noise insulation is carried out with our own hands , without the involvement of masters from the outside.
Where does the noise come from and how successful can it be against it?
There are several main reasons:
- running engine;
- miscalculations in the aerodynamics of the body and its elements;
- tires, more precisely the tread pattern, and the type (winter or summer).
In addition, there is another reason : various squeaks, knocks, vibrations and rattles can occur from loose or worn fasteners during operation. But this is more related to the conscientious implementation of the recommendations for operation by the owner of the car and the service mechanic performing the service. We will not talk about the rattling of the contents of the trunk, glove box and other luggage either.
And now about the main sources of noise and in more detail ...
Engine
When it is working, a large number of moving and rotating parts generate not only noise, but also vibrations, which must be absorbed by special shock-absorbing pads under the engine mounts. In any case, vibration is transmitted to the body, but if one of the linings is damaged, then the vibrations will certainly generate annoying noise.
Aerodynamic noise
As a rule, they are generated not by design miscalculations, but by the owner’s desire to replace the standard part with a more, in his opinion, suitable. These can be exterior mirrors, antennas, foglights, crossbars on rails, spoilers, an external trunk, etc. The list is endless.
Tires
They, too, can become a source of increased noise due to the width and tread pattern. It should also be borne in mind that winter tires are noisier than summer tires, especially the so-called "studs".
Therefore, before embarking on a decisive fight against noise, you need to carry out an initial diagnosis and determine the primary source .
Typically, soundproofing means reducing outside noise to owner-defined limits. For its implementation, special noise-absorbing materials (vibration dampers and sound insulators) are used, which are mounted in places that are conductors or resonators of noise. In some cases, protective structures are additionally manufactured in the form of casings of various shapes.
Where to look for the source of annoying noise is now clear to us. There is little to do - to defeat or, at least, weaken all these overtones. Having established in this decision, it is better to implement it with an experienced specialist. And not only because the car is a source of increased danger, but because the success of the work performed largely determines their quality. And here without a specialist in any way.
