Living in apartments with thin walls and ceilings, we were faced with the problem of noisy neighbors who were tagged like a herd of elephants, or listened to RAMMSTEIN for hours. Sometimes even a desire arose to "kill neighbors, that prevent sleep." But you can do it differently, namely, to make noise insulation of the apartment with your own hands.

Types and characteristics of noise
The walls and ceilings of modern apartments, especially panel ones, are literally created for the transmission of sound at a distance. The minimum thickness of ceilings and walls, multiplied by vibrating amplitude fluctuations, contributes to the formation and passage of noise in some cases, even exceeding the prescribed 85 dB. Conditionally noise, intrusively penetrating into the apartment, according to the nature of its distribution is divided into shock and air. All mechanical movements from falling objects or moving furniture belong to the shock type.
In the air type, the generated vibrations cause and amplify sound waves by the oscillation of air. But it does not help us much if the apartment is constantly noisy. How, after all, to improve noise insulation?
Materials for apartment soundproofing
To improve the noise insulation of the apartment, you can use the following materials:
• Sound reflecting
• Sound-absorbing.
Reflective materials are able, by virtue of their physical qualities, to suppress vibration of sound waves. Sound reflecting materials include lightweight sheet and foamed synthetic materials: melamine and rubber.
However, such materials are suitable for soundproofing shock-type noise and are used for floor coverings.
Sound-absorbing materials have a porous structure and are made of natural fibers, such as basalt wool. It is possible to improve the noise isolation of one's apartment independently by alternating layers of sound-absorbing and sound-absorbing materials.
How to make noise insulation of an apartment by yourself
Sound insulation of ceilings
The noise insulation of the apartment itself can start with the ceiling finishing with gypsum boards, reinforced with a pre-lining of soundproof materials. Sound insulation of the ceiling is carried out with the use of ceiling systems:
• suspended ceiling
• the filing
• tension.
For soundproofing material, in this case, basalt cotton wool, chamotte, polyurethane foam blocks or cork cover are used. To fix soundproof materials for noise insulation of the apartment's ceiling metal frames or brackets are arranged. The spaces between the ceiling and suspended structures are filled with soundproof material. Further finishing of drywall sheets is done in the traditional way.
Noise insulation of European quality for the ceiling from professionals is presented for reference in the video.
Sound insulation of walls
To improve the soundproofing of the walls of the apartment, you can by fully sealing the joints between the panels of the walls and the floor with silicone sealant. Sometimes, however, such events are not enough and heavy artillery is going into battle. In this case, for noise isolation of the apartment walls use special substrates and partitions.
What should be done initially for soundproofing walls? First, find all sources of penetration of "alien" sounds. These can be cracks of any degree of openness, holes and sprinkled joints. This is exactly what you need to thoroughly fill in.
Next, soundproof the electrical outlets, these insidious sound conductors, using plaster putty. By the way, after soundproofing of sockets it is recommended to check up their working capacity. And, finally, soundproof walls using plasterboard, foam or mineral wool. To reduce the penetration of noise, it is necessary to increase and increase the thickness of the walls.
The filling of the space between the wall surface and the sheets of gypsum board is best of all with mineral wool plates. It is first necessary to familiarize yourself with and pay attention to the soundproofing characteristics and conductivity and sound absorption coefficients of the plates.
Mounting of the profiles of the frame and fixing of the suspensions is carried out on the soundproofing substrate. An excellent material capable of significantly reducing noise is the cork substrate and plates.
Detailed instructions for soundproofing the walls are provided in the video.
Sound insulation of the floor of an apartment
Sound insulation of the floor of the apartment with its own hands is carried out using the technology of "floating floor". The design of the "floating floor" is a massive screed of DSP or concrete, mounted on the interfloor overlapping. The floor covering in this case is as if in a "suspended" state with respect to the soundproofing layer.
The peculiarity of the screed of a floating floor is the absence of rigid ties with the lateral surface of walls or partitions. As a soundproofing soundproofing plates are used, reinforced with a screed and plinths of soundproof material. The intermediate layer is an elastic soundproof material.
Vibration release materials are used as a gasket:
• basalt wool
• foamed synthetic polymer materials
• Glass wool.
The existing technology of "dry floating" screed is based on the use of gypsum fiber boards with the laying in two layers with overlapping joints. Places of gluing joints and layers are treated with special glue.
Overlying the soundproofing system, laminate, parquet or other coatings are laid. The option of a floating floor is most actual because of good sound insulation. The advantages of this noise isolation system are obvious:
• complete absence of mechanical fastening
• Simple and affordable technology that a beginner can learn
• the presence of a gasket membrane improves the thermal performance of the floor
• technological loads for this type of sound insulation are distributed evenly over the entire surface of the floor.
