Modern soundproofing materials

The amount of noise in the modern city exceeds all accepted norms. This indicator is a serious irritant and the cause of neurosis, insomnia and diseases of the central nervous system. Modern materials for insulating noise help to eliminate this problem and protect your house from external stimuli.

Types of noise

Different sources create a different nature of sound. Experts distinguish three of its types:

• Air-arises due to the car passing by the building, the life of people and animals, the work of various equipment.
• Shock - it occurs with the contact effect of an object with a wall. For example, the work of the perforator, clogging nails, the clatter of the legs.
• Structural - occurs when the sounds are transmitted through structural elements of the building.

Ways to isolate 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 the noises are isolated directly at the stage of building a residential building, but often there is a need to install additional structures. The practice of noise isolation distinguishes 4 main directions in which work is underway:

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

To eliminate noise in individual rooms, they use materials for soundproofing, they are distinguished by two types:

1. Preventive vibrations.
2. Absorbing and scattering noise.

The principle of getting rid of noise is pushed away from a sound wave by extinguishing the density of the walls. The soundproofing structure not only isolates the internal space from external noise, but also absorbs them. Sound insulation materials vary in their properties and require the construction of structures of various configurations.

Light foamed materials for sound insulation

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

The popularity of foamed isolation is due to an affordable price and ease of styling. They are used as a part of the structure of several layers as one of the layers. But these materials isolated only vibrations from the structure in its source. An air noise isolation indicator in these materials. It is advisable to use in the form of a part of a slightly loaded structure, which is supplemented by the absorptions of noise of other categories.

Also, soundproofing materials of structural noise are used as absorbing vibration of gaskets in the installation of plumbing or various equipment, for example, washing machines or household pumping stations. A closed porous basis of isolation makes its use as impeccable as facing materials. For this purpose, only a volume shape of waves or pyramids are suitable, they are used for sound correction of rooms in professional studios.

Sound -absorbing materials

The second volumetric group of soundproofing is represented by products from basalt and kaolin wool, foamed glass, chamotte, swollen perlite, polyester foam, polyethylene foam, polyurethane foam, foamopylene, etc. These materials do not reflect, but absorb noise. The most functional of them is mineral wool made of rocks. It is hydrophobic, fire resistant, vapor permeable and does not pose a threat to health. It is used to protect against noise in premises for various purposes - from residential apartments to specialized institutions with high requirements for acoustic properties of materials used.

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

• insulating panels from noise;
• vibro-acoustic panels are layered;
• additional insulation panels;
• sentwitch Panels.
