Modern sound insulation materials

The number of noise in a modern city exceeds all the received norms. This indicator is a serious irritant and the cause of neuroses, insomnias and diseases of the central nervous system. Modern materials for noise isolation helps to eliminate this problem and protect their home from external stimuli.

Types of noise

Different sources create a different character character. Experts allocate three of its kinds:

• Air - arises because of the cars passing by the buildings, the vital activity of people and animals, the work of various equipment.
• Impact - occurs with the contact impact of the item with the wall. For example, the work of the perforator, clogging of nails, football legs.
• Structural - occurs when the transmission of sounds through the structural elements of the building.

Ways of insulation of the room from noise

For good sound insulation of the room from noise, it is necessary to isolate it in all three directions. Partially all noises are isolated directly at the stage of building a residential building, but often the need to install additional structures. The practice of insulation of noise allocates 4 main directions for which work is underway:

1. Installing additional partitions.
2. Laying of added layers of material on the floor or ceiling with dense insulation of the joints.
3. Installation of insulating window frames and doorways.
4. Noise insulation of house communications.

To eliminate noise in separate rooms, use materials for sound insulation; they are released two types:

1. Preventing oscillations.
2. Absorbing and scattering noise.

The principle of getting rid of noise is repelled from the arrangement of the sound wave by increasing the density of the walls. Soundproofing design not only isolates the internal space from external noise, but also absorbs them. Soundproofing materials differ in their properties and require the construction of various configuration designs.

Light foamed materials for sound insulation

These sound insulation materials for the walls are most popular and isolate rooms from structural vibrations. These are light foamed products based on polyurethane, synthetic rubber, etc. These are lightweight materials from tube and fiberglass in rolls or plates.

The popularity of foamed isolation is due to the available price and simplicity in laying. They are used as a detail of a design of several layers as one of the interlocks. But these materials are isolated only vibrations from the design in its source. The insulation indicator from air noise in these materials is low. It is advisable to use in the form of a part of a slightly loaded structure, which is supplemented by the absorbers of noise of other categories.

Also, the sound insulation materials of structural noise are used as absorbing strip vibration when installing plumbing or various equipment, for example, washing machines or household pumping stations. The closed porous insulation base makes its use as facing materials inexpedient. Only having a volumetric waveform or pyramid materials are suitable for this purpose, they are used for sound correction of rooms in professional studios.

Sound absorbing materials

The second volumetric soundproofing group is represented by products from basalt and kaolin wool, foamed glass, shamot, stripped perlite, polyurethane foam, polyethylene foam, polyurethane foam, penostopylene, etc. These materials do not reflect, but absorb noise. The most functional one is mineral wool from rocks. It is hydrophobic, fire-resistant, vapor permeable and does not represent health threats. It is used to protect against noise in rooms of different purposes - from residential apartments to specialized institutions with high demands on the acoustic properties of the materials used.

A separate category of noise absorbing materials is ready-made structures. These materials do not require the installation of complex configurations and quench the sound of all levels. Also, many finished designs are not only an element absorbing noise, but also a high-quality decor for the room. In this category:

• panels are insulating from noise;
• vibro-acoustic panels layered;
• panel of added isolation;
• saintwich panels.
