Material for soundproofing. Noise isolation with their hands: what materials are required?

Reducing the impact of third party sounds is a necessary condition to ensure comfort. To achieve normalization, noise performance, use of special materials – insulators and suppressors. Depending on the origin and operation parameters can be applied in different areas. In particular, in recent years has become a popular material for acoustic insulation of technical equipment, including cars. Available technology the application of such coatings allows for any driver to ensure acoustic comfort in the cabin with his own hands. Not lose their relevance and the traditional means of soundproofing, is designed for rooms. Perhaps they should start reviewing.

Materials for sound insulation of premises

The apartments and homes of soundproofing material should form a barrier to the propagation of noise waves by absorption and scattering. A classic means of ensuring this task is facing a slab of drywall. In addition to protecting from external noise, it also performs a decorative role and contributes to the warming function. A separate category is represented by a material for sound insulation based on wood raw materials. Typically, in the manufacture of such panels, use the fiber coniferous tree. Among the advantages of this insulator can be note worthy sound-absorbing function and environmental cleanliness. Due to the natural origin of such insulators can be used in living rooms. The best solution to protect the premises from the shock of the noise levels can become material with the use of sand filling. This is the plate that resemble the usual veneer, but inside they contain a mixture of wood raw material and quartz sand.

Material for soundproofing of cars

The peculiarity of the process of sound insulation of the car is providing the dual functions of material – protect from vibration and noise impacts. To accomplish the first task use vibrocenter. It is a heavy coating that repaying the energy fluctuations, transforming it into heat radiation. Specifically for noise protection this material should not be used, although it effectively copes with the suppression of low frequencies. Full noise auto still requires the use of special absorbers, which will allow you to perform the second task. Outwardly, this material is similar to Styrofoam, but there are serious differences in the structure.

In the case of automobile insulators, emphasis is placed on efficiency cell structure, which cancels noise waves in the transition from one barrier to another. Worth noting and external protection should be provided with material for sound insulation to protect from mechanical damage. To do this, manufacturers use film shiny surface.

The Installation of insulators

In the case of home insulation, and installing shumopogloschenie the car used the same principles of installation. They usually involve landing on glue or mechanical mounting by means of special fasteners. In terms of technical implementation of many motorists affordable adhesive insulation with their hands. What materials are required to perform this operation? It is very important to choose reliable and high-quality binder. Usually the glue comes with the kit insulator, but it may not be. Before installation, the surface should be degreased, which will increase adhesion between the materials. The optimal solution would be a combination of two installation methods. In this case, the glued panel is additionally fixed with staples or screws.

What to consider when choosing a cell?

Requirements for sound insulation materials are different. Obviously, the level of absorption of sound is the main criterion, but even it is not always the determining factor. A lot depends on operating conditions and ability to protect the panels from moisture and mechanical damage. Still the best insulation for car or room – one that is able to provide and protect its own structure. This is important, because the durability of the material eliminates problems in the process of operation. For example, if the technology involves the installation of the insulator under the finishing trim, the premature deformation of the silencer will lead to necessary renewal of the decorative coating.

Howis insulation?

A Specialized production of proofers are engaged in many enterprises, including many domestic firms. Most affordable panels you can buy for 150-200 $ /m². This is a good options for partial redemption from third party sounds, but they will not save, if you want high quality and deep noise isolation. The price of the material, based on average requirements for acoustic comfort, varies from 400 to 600 $ /m².

It is not always the task of insulating materials are limited to only one function of noise reduction. The modern lines of the manufacturers are quite common multifunctional coatings, which also have aesthetically appealing look and warming capacity. However, their main task is still insulation. The price of the material in such series can reach 1500 $ /m². Such a high cost not only due to the wide range of functions and environmental cleanliness of the unit.

Conclusion

Installation of the materials for noise reduction does not always justify the expectations of users. Even expensive and high-quality products often receives critical reviews. The weak effect may be related to the fact that the object initially has a low qualities of protection from the sounds. For example, the sound insulation of the car will give the minimum result, if the body structure has a lot of backlash and generally unsatisfactory sealing. The same applies to residential premises. Thin walls, use of wood frames in window openings and lack of quality finish – these and other factors will not allow the isolator to perform their tasks at the appropriate level.
