Features of the choice of materials for sound insulation in apartments

Constant noise from neighbors or from the street is a problem familiar to many residents of apartment buildings. Renovation work, loud music, baby crying, the hum of traffic outside the window — all this can turn your own apartment from a fortress into a source of constant stress. Noise insulation becomes the solution to the problem, but its effectiveness directly depends on the correct choice of materials.
Before you run to the store, you need to understand the nature of the noise that is bothering you. There are two main types of noise: airborne and structural (or impact). And to combat each of them, different approaches and materials are needed.
Air noise versus shock
Air noise is sound waves that travel through the air. This includes talking, shouting, and the sound of a running TV or music system. Sound-absorbing materials are used to combat it. Their task is to "catch" the sound wave and extinguish its energy.
Impact noise is caused by mechanical effects on building structures: footsteps, furniture movement, and the operation of a rotary hammer. This sound is transmitted directly through the walls and ceilings. To drown it out, sound-proofing, vibration-damping materials are needed, which create a barrier and prevent vibrations from spreading further.
The Noise Fighter's Arsenal
There is a huge amount of noise insulation materials on the market. They can be divided into several groups.
Sound-absorbing materials (to combat air noise):
- Mineral wool (stone or basalt): One of the most popular and effective materials. It has a fibrous structure in which the sound wave sinks and fades. It is used in frame structures for walls, ceilings and partitions.
- Acoustic foam, cork: Often used for finishing in recording studios or home theaters, but can also be used in residential areas.
Soundproof and vibration damping materials (to combat impact noise):
- Heavy membranes: Thin, but very dense and heavy rolled materials. They work on the principle of mass: the more massive the barrier, the more difficult it is for sound to pass through it. They are mounted as part of multilayer structures.
- Floor coverings: Special materials made of cork, foamed polyethylene or rubber, which are laid under laminate or parquet to dampen impact noise.
Most often, to achieve a good result, an integrated approach is required — the creation of a so-called "pie" from different types of materials.
The price of silence
Noise insulation is not something worth saving on. Cheap and thin materials will have minimal effect, and you will just waste money and time. Effective noise insulation always implies the creation of a multi-layered structure, which, unfortunately, "eats up" part of the useful area of the room.
The choice of specific materials and the thickness of the structure depends on the type of noise, budget and features of your room. Sometimes it is enough to isolate one wall, and in some cases complete noise isolation is required in a circle. In any case, properly selected materials and proper installation are the key to peace and quiet in your home.
