Material for noise insulation. Noise isolation by the hands: what materials are required?

Reducing the impact of third-party soundsis a prerequisite in providing comfort. To achieve the normalization of noise indicators, special materials are used - insulators and suppressors. Depending on the origin and operational parameters, they can be applied in different areas. In particular, recently the material for noise isolation of technical means, among which automobiles has become popular. Available technology for the use of such coatings allows any driver to provide acoustic comfort in the cabin with their own hands. At the same time, traditional means of soundproofing intended for premises do not lose relevance either. Perhaps, with them and it is necessary to begin the review.

Materials for soundproofing of premises

In apartments and houses soundproof materialshould form an obstacle for the propagation of noise waves by their absorption and scattering. A classic means of ensuring this task is a facing plate made of plasterboard. In addition to protection from external noise, it also performs a decorative role and contributes to the increase of the insulation function. A separate category is the material for noise insulation based on wood raw materials. As a rule, in the production of such panels, coniferous wood fibers are used. Among the advantages of this insulator is a worthy noise-reducing function and ecological purity. Due to natural origin, such insulators can be used in living rooms. The best solution for protecting premises from impact noise may be a material with sand filler. These are slabs, which outwardly resemble the usual lining, but inside contain a mixture of wood raw materials and quartz sand.

Material for car noise isolation

A special feature of the car soundproofing processis to provide a dual function of the material - protection from vibration and noise effects. Vibrodamps are used to perform the first task. These are heavy coatings that cancel out the vibrational energy, transforming it into thermal radiation. Especially for noise protection this material should not be used, although it effectively copes with the suppression of low frequencies. A full noise insulation of the car still requires the use of special sound absorbers, which will allow you to perform the second task. Outwardly such material is similar to foam rubber, however there are serious differences in the structure.

In the case of car insulators,a bet on the efficiency of the cellular structure, which extinguishes noise waves during transitions from one barrier to another. It should be noted and the external protection, which must be provided material for noise insulation in order to protect against mechanical damage. To do this, manufacturers use film shiny coatings.

Installation of insulators

And in the case of home insulation, and when installingnoise absorbers in the car use the same installation principles. Usually they mean landing on glue or mechanical installation by means of special fasteners. In terms of technical implementation, many motorists are more readily available with adhesive self-insulation. What materials are required to perform this operation? It is very important to choose a reliable and high quality binder. Usually the glue comes with the insulator kit, but it may not be. Before installation, the surface should be degreased, which will increase the adhesion between materials. The optimal solution will be a combination of two methods of installation. In this case, the glued panel is additionally fixed with clips or screws.

What to consider when choosing an insulator?

Requirements for noise insulation materials aredifferent. Obviously, the level of sound absorption is the main criterion, but even it does not always become the determining factor. Much depends on the operating conditions and the ability to protect the same panels from moisture and mechanical damage. Still, the best noise insulation for a machine or a room is one that is able to provide and protect its own structure. This is an important point, because the durability of the material will save problems in the process of operation. For example, if the technology involves the installation of an insulator for the finish lining, premature deformation of the muffler will also lead to the need to renew the decorative coating.

How much does noise insulation cost?

The specialized production of soundproofing devices is carried out by many enterprises, many of which are domestic firms. The most affordable panels can be purchased for 150-200 rubles / m2. These are good options for partial disposalfrom third-party sounds, but they will not save if high-quality and deep noise insulation is required. The price of the material, oriented to the average requirements for acoustic comfort, varies from 400 to 600 rubles / m2.

Not always the tasks of insulating materialsare limited only by one function of noise cancellation. In modern manufacturers' lines, multifunctional coatings are quite common, which also have an aesthetically appealing appearance and thermal insulation. However, their main task is still noise isolation. The price of the material in such series can reach 1500 rubles / m2. Such a high cost is due not only to a large range of functions, but also to the ecological cleanliness of the insulator.

Conclusion

best sound insulation

Installing noise suppression materials is not alwaysjustifies users' expectations. Even the address of expensive and high-quality products often receive critical reviews. A weak effect may be due to the fact that the object initially has low qualities of protection against sounds. For example, car noise insulation will give a minimal result if the body structure has a lot of backlashes and generally unsatisfactory sealing. The same applies to living quarters. Thin walls, the use of wooden frames in window openings and lack of quality finishing - these and other factors will not allow the insulator to perform its tasks at the proper level.
