Soundproof walls - materials for different types of noise

Why soundproofing issue so urgent?

modern housing in urban environments - is most often in high-rise apartment building, surrounded on all sides by the same apartment living cells.The whole house is more like a cell.It is often carried out on the floors of local repair work perfectly audible throughout the house.And instead of resting, weekends all the neighbors enjoy the symphony of punching walls or other similar sounds.

From these examples we can conclude that the noise sources can be of different nature of origin and propagation environment.Indeed, if the sound of the piano, the radio or the TV is mainly spread in the air, the shock and mechanical impact on the structure of solid construction house call distribution through the structure of shock waves of nature.

and to eliminate various types of noise to be used substantially different from each other by insulation of walls in the apartment, the materials for which it is necessary to choose, taking into account the difference between the above characteristics.Also, this often results in the need to use different approaches for soundproofing.

Eliminate noise types, depending on their nature

Among the many sound insulators distinguish the most common of lung polyurethane foam, polyethylene, melamine and other components, as a rule, have a roll or sheet form of release from the manufacturer.

Such insulation materials are best contribute to the prevention of noise, with shock-mechanical nature and propagating in the structure of the building.It may be even better sound insulation apartments, because it differs sufficiently low cost, can be widely used in the insulation of floors, ceilings, in joints with engineering services, often serve as sources of noise and the conductor.

Generally, this group of materials prevents the transmission of sound vibrations to doors, walls and other obstacles, moreover, the sound is absorbed and dissipated partly or entirely on the material.

For the second type of noise propagating in the air, more and more efficient use of sound absorption materials.Their base is usually comprise different fibrous structures.It can be wool (mineral on the basis of natural or synthetic) or prepared panels, blocks and other thereof.

providing a high enough result, noise insulation material for the walls can have a sufficiently large thickness, which is not always acceptable in a small room sizes.Also, such insulators are frequently used as a packing structure or plasterboard false ceilings in the subspace.

New technologies in the field of protection against noise

Among all others, the most modern and high-quality sound insulation in the apartment, the materials for which are characterized by high purity and safety, according to the manufacturer, - a membrane insulation.This type of insulator has a small thickness (up to 8 mm), with properties similar to the sheet lead and operates like the sound absorbing membrane.

The basis of the material lies with the advanced technology of manufacture of natural material argonita.Insulator produced predominantly without the use of extrusion technology (non-foamed material) and without the use of fibrous structures.Among other advantages should be noted the high fire resistance of these membranes.

And it is important, when choosing materials or a combination thereof should be provided the best sound insulation of walls, because among the criteria influencing the decision is the first.Next, you need to pay attention to what the value of the coefficient of sound insulation.At the same time equal values ​​of coefficients can be provided with different materials thick.With all things being equal preference should be given less fuel.

According acoustic characteristics should be preferred insulators that can neutralize the low-frequency spectra.It is important to pay attention to the manufacturer's warranty and supplier.And, of course, need to take into account the hazards that accompany this or that type of material.
