Sound-absorbing material - reliable protection of your home

Modern life is filled with various sounds. This is the noise of cars passing along the street, and the work of household appliances, and all sorts of activities of neighbors, whether it's their conversations or regular repairs. All these manifestations are collectively called household noise, which propagates in the audio range from 16 Hz to 20,000 Hz. Noise pollution is divided into two groups:

1. Structural noise.

2. Air noise.

Their main difference lies in the environment of the spread of vibrations. In the first case it is solid bodies, and in the second - air.

Since such acoustic influences can be not only unpleasant for perception, but also dangerous for human health, care must be taken to ensure that sufficient sound insulation of the room is provided in the living rooms and other places of residence of the person.

One of the most common means of protection against noise pollution is air. To its features and advantages can be attributed ubiquitous placement and high penetrating ability. Thus, various structural elements and building materials, which contain closed areas filled with air, conditionally represent a noise shield, which has sufficiently good protective characteristics. The presence of closed air gaps in the cavity of doors and windows will reliably protect your home from the negative effects of noise pollution of street life.

In turn, sound absorbing material makes it possible to isolate rooms with an increased noise level from the adjacent areas. Such facilities include cinemas, shopping and entertainment centers, various sports buildings and facilities, as well as office space. With the correct location and proper installation of protective structures, you can achieve a significant reduction in the power of reflected vibrations and waves, which will reduce the impact or completely remove unnecessary noise.

The sound-absorbing material must have the required characteristics and meet stringent requirements. All this is determined by the quality indicators, for example, the amount of sound absorption, the range of which is located from 0 to 1. As construction practice shows, the best sound absorption coefficient is possessed by materials that can pass air, with open long pores. These include glass and mineral wool, various felt fillings, and the like.

In addition, each sound-absorbing material must meet high requirements for environmental friendliness and fire safety. This is due to the fact that often such substances will be used for interior finishing works. Therefore, they should fully possess such qualities as convenience in operation, durability, moisture resistance and aesthetics.

Thus, the sound-absorbing material must be fully used at the initial levels of construction, isolating the zones of increased noise level, and also providing soundproofing of the premises from external influences.
