Types of sound-insulating materials

With each passing day more and more acute question provide comfort indoors. And the main enemy becomes noise in its decision. It is therefore vitally important factor is the insulation in the apartment. To ensure that it is necessary to examine what are the sound-proofing materials, their properties, advantages and disadvantages. And only after that think about the choice of what modern materials make a noise insulation wall in the apartment. And besides, you need to determine, what noise should be eliminated.

Types of noise and its sources

To begin, it should be noted, that there are only two kinds of noise:

  1. Air, which is carried directly by air. It may be cries, loud noises, music, etc.. Typically, such a noise is able to penetrate through any cracks and crevices, and in addition, and through the windows. Mainly with regard to airborne noise, it becomes a storm of office and living rooms.
  2. Structural (shock). Distributed through a medium solids. Structure-borne noise is largely a problem of industrial premises. It represents sound waves, that move on solids, overlaps, walls. Examples of such noise can be a tramp, jumping, the sounds of working tools, the vibration from the speakers.

And depending on the type of noise, It depends on the selection of the required isolation. The correct choice is determined by, on what exactly you are going to protect the noise. In general the following types of buildings are in need of protection: industrial premises, office and Living spaces.

The spread of noise

Besides, the choice will affect directly and noise, you want to measure. It will have to purchase special equipment, or call a specialist at home.

Speaking of the statutory noise performance, note the following:

  1. In accordance with the GOST snip daytime acceptable noise value equals 40 decibel, by volume inaudible to humans it can be compared with the usual conversation. At the same time, the volume should not exceed 55 dB, which equates to a weak slap on the table.
  2. Speaking about the time of day night, here the recommended volume 20 dB, extreme threshold, established by the legislation of 40dB ( for violation of administrative responsibility).

Thus the choice of materials is required to approach responsibly, because it depends also on the type of noise, and the required level of insulation. Each material has its own index of noise reduction, ie. indicator, which fall comprehend and goes beyond the volume of the room.

Directly on insulation measures still need to take care in the design process. It can achieve an appropriate arrangement of partitions and rooms. But this possibility is not always available, because, We most of the time devoted to examining materials, which do not require an additional arrangement of sound insulation for walls and partitions, as well as the dismantling of structural elements.

Sound-proofing materials

Fully considering this category, it may be noted about twenty kinds of such materials, and try to determine what insulation for walls is best suited. Because pay attention only to the highest-quality and most popular options of sound-absorbing materials.

Şumoplast

The first material, which we will consider becoming shumoplast. This unique material, which is made of elastic granules, acrylic pigment and rubber additives.

Special types of materials

Do not forget, it's not all materials, wherein, some of them are only allowed under certain conditions, in that all the others are universal. For example, these are machine insulators, which can be used in the construction industry.

But sound insulation of ceilings, walls and floor a little. It is extremely important to pay attention to doors and windows. As a solution to the problems with windows you can consider this option, as the installation of PVC windows profile. Sound insulation characteristics has a very high. Normally the space between the two windows filled with inert gas. The most common and frequently used gas - argon.

As for the doors, there is usually used a multilayered structure, which consists of chipboard, MDF and laminate. The space between the door and door frame sealed by special gaskets for sealing. Types of modern sound-proof materials are full of variety, but you need to pomnitt, that only comprehensive measures turn out to achieve a high level of isolation from external noise.
