It’s not for me to tell you what it is to wake up at 3 a.m. Or maybe your neighbors are big lovers of music? The option is not excluded when you live near the railway or highway, perhaps your house is located on the most lively street of the city.
Be that as it may, to be in a stressful state and listen to all these extraneous sounds is far from the most pleasant activity. The noise distracts, does not allow to concentrate and relax, in short, living in noise and having a stable psyche is almost impossible. It causes irritation, the absence of normal sleep is very negative for your health.
To protect yourself and your loved ones from extraneous sounds, it is customary to use special materials in construction, which create a barrier on the way of noise.
About sound insulation.
Why is soundproofing? Its main task is not to let the sound through the wall of the structure. She just reflects the noise to where he came from. Dense building materials: concrete, drywall, wood, brick, etc. They are also reflectors of sound.
Why is it necessary?
All measures for the soundproofing of the premises are aimed at suppressing sounds. Noise -absorbing building materials have a different structure. The ability to absorb noise is measured using the noise reduction coefficient. Noise reduction coefficient changes from 0 to one. When it is zero — the sound is completely reflected. If the sound is completely absorbed — the coefficient is equal to one.
Absorption of extraneous sounds.
The task of sound insulation is to absorb extraneous sounds, to prevent reflection in the direction of the protected room.
When conducting measures to protect against noise in private households, it is optimal to use soft insulating materials.
When choosing a soundproof material, it is important to determine the nature of the sound.
There is an air noise, which is created by working electrical appliances, people’s conversations, cars noise. In order to protect yourself from direct exposure to ceilings, whether drilling, rearranging furniture, clatter — and this is already shock noise, elastic soundproof gaskets are used.
So, in order to successfully withstand shock noise, you need to use elastic soundproofing materials with a closed cellular system. To reflect air noise, it is necessary to use fibrous and porous materials.
