It is possible to reduce the audibility in the apartment with the help of sound-insulating and sound-absorbing materials. Noise insulation of the ceiling, walls and floor has its own characteristics, the knowledge of which will help to ensure comfortable living in your living space.

To reduce the audibility in the apartment, you first need to decide on its location: ceiling, wall, bottom ceiling and all this in a complex. Now you should try to understand what kind of noise interferes with a quiet life in your apartment. This knowledge will come in handy when choosing a soundproof material.

How to choose the right sound insulation

A sound wave, meeting an obstacle, is partially reflected from it, partially scattered, penetrating through the obstacle.

Sound-insulating materials help to reflect the energy of an acoustic wave, sound-absorbing materials extinguish it inside themselves. The first ones "work" more effectively if the nature of the wave is "airy" (voice, barking, music) or "mechanical" (noise of footsteps, slamming the door). For example, to reduce the level of the incoming sound by 50 dB, either a 2 m thick layer of a sound absorber or a sound insulating obstacle only 1 brick thick is required. If the nature of the acoustic wave is "structural" (propagates through communications, floor slabs), it is better to use materials that absorb noise.

Multi-layer structures will help to achieve silence in the room. With their help, it is possible to achieve a reduction in the level of noise penetrating through the walls, from 40-50 dB, which is usual for apartment buildings, to 25-30 dB. For comparison: absolute silence - 20 dB. It should be understood that the effectiveness of any soundproofing materials depends on their thickness. The quality of the products plays a secondary role here.

Soundproofing structures, consisting of several layers, are easy and convenient to install, but they will make you sacrifice useful space. However, this is the only way to ensure a comfortable stay, since it is impossible to achieve significant changes when using materials with a thickness of 20-30 mm.

Soundproof multilayer structure consists of alternating layers of "hard" (GKL, LSU, GVL, brick, wood concrete) and "soft" (sound-absorbing material). This is the most effective way to reduce the noise level, since the acoustic wave, upon encountering such an obstacle, is reflected from the first layer, and in the second it “sinks”. It is important to choose dense sound-absorbing material.

The best absorbers of "air" noise are as follows: felt, fiberglass, fibrous heat insulators (mineral wool, etc.), silica fibers. Cellular materials will better cope with "mechanical" sounds: polystyrene foam, polyethylene foam, polyurethane foam, cellular concrete. Among modern soundproofing materials for walls, the high efficiency of the ZIPS tongue-and-groove panels is noted. The thickness of these products is 7 cm, but they are able to reduce the noise level by 10 dB.

Soundproofing the floor requires a different approach. Thin (3 mm) glass wool slabs "Shumanet-100" will be effective here. These products are placed under a self-leveling screed with a thickness of at least 6 cm, which will reduce the sound level by 23 dB. If you use "Shumanet - P60" - by 37 dB. The bottom ceiling can be soundproofed with cork, expanded polypropylene, silica fiber. These materials are laid in the openings between the logs or on the rough floor.

You can soundproof the ceiling with a suspended acoustic structure. Compressed fiberglass or mineral wool boards can be used here. They reduce the noise level by 10 dB. In such a suspended ceiling, you can safely hide electrical wiring.
