Sound-absorbing material is a reliable protection of your home

Modern life is filled with different sounds. This and the noise of passing street cars, and working appliances, and all kinds of activity of neighbors, whether they talk or another repair. All these symptoms collectively are referred to as domestic noise, which is distributed in the audio range from 16 Hz to 20 000 Hz. Noise pollution are divided into two groups:

1. Structural noise.

2. Aerial noise.

Their main difference lies in the environment the transmission of vibrations. In the first case, a solid body, and the second air.

Because these acoustic effects can be not only unpleasant to see, but dangerous to human health, it is necessary to ensure that, in living rooms and other places of human habitation was provided with sufficient zvukoizolyatsii of the room.

One of the most common means of protection from noise pollution is air. Its features and advantages include widespread deployment and high penetration capability. Thus, the different structural elements and building materials that contain closed region filled with air, conventionally represent a noise that has a fairly good safety features. The presence of closed air gaps in the cavity doors and Windows to protect your home from the negative effects of noise pollution, street life.

In turn, the sound-absorbing material provides the ability to isolate the room from noise from adjacent areas.

Sound-Absorbing material should possess the desired characteristics and to meet the strict requirements. All this is determined by the quality indicators, for example, the magnitude of the absorption, the range of which is from 0 to 1. Shows the construction practice, the best sound absorption coefficient have materials that can leak air, open, long time. These include glass and mineral wool felt of various fillers, etc.

In addition, each of the sound absorbing material needs to meet high demands for environmental friendliness and fire safety. This is due to the fact that often such substances will be used for internal finishing works. Consequently, they must fully possess qualities such as ease of use, durability, moisture resistance and aesthetics.

Thus, sound-absorbing material necessary to fully use even in the early levels of construction, insulating areas of high noise levels and providing sound insulation of buildings against external influences.
