We bring to your attention the results of measurements of the soundproofing characteristics of structures used by our company for soundproofing walls.
Macsound Prof material was used as the main soundproofing material, and Acoustic mineral wool as an auxiliary.
Knauf Titan 12.5 mm drywall was used as partitions. To reduce the vibration that the structure transmits and receives, the drywall profile was fixed using VIBRONET vibration fasteners.
8 variants of combinations of these soundproofing materials were studied in combination with a different number of drywall sheets outside and inside it.
The results were very interesting and quite unexpected for many specialists in soundproofing rooms.
For example, a structure assembled from Macsound Prof, which was placed between two layers of 2 sheets of drywall, turned out to be equivalent in terms of sound insulation index with a structure in which a layer of acoustic mineral wool was used between the wall and the first layer of drywall. And outside, another layer of Macsound prof was installed and a layer of two sheets of drywall.
At the beginning of the article, information is provided on each specific soundproofing option, and in conclusion, for the convenience of comparing the effectiveness of each of the methods, we summarized the results of all studies in one block.
Macsound 20mm or 40mm thick, which is placed between two sheets of drywall.
For the measurement, sheets of Macsound Prof soundproofing material 20 mm thick and 40 mm thick were alternately used.

Macsound 40 mm thick, which is located between two sheets of drywall on the outside and one sheet on the side of the soundproof surface. between the inner sheet of gypsum board and the soundproofing surface there is a soundproofing cotton wool.
Consists of pieces of acoustic polyurethane foam, rubber, reinforcement fabric.
It is a uniformly porous elastic material with an open small pore, due to which sound energy is absorbed and converted into thermal energy.
Depending on the placement and design, it is used both to absorb airborne, acoustic noise and to significantly reduce impact and structural noise.
Suitable for absorption and isolation of low, medium and high frequencies.
Eliminates the effect of rattling, "box resonance".
Prevents the formation of sound bridges.
Very effective when used in wall partitions.
It is also used for wall cladding in rooms where there is noisy electro-mechanical equipment - elevators, hoods, machine tools.
It is used as insulating gaskets, bumpers, as well as to protect the transported cargo from damage, for example, when transporting glass, antiques.
When used as a sound absorbing material, Macsound is effective in absorbing the entire audible and perceptible sound spectrum.
More efficient than acoustic mineral wool due to its density from 60 to 300 kilograms per cubic meter, it saves space, does not crumble.
Suitable for interior work.
Also used for wall soundproofing, ceiling soundproofing and floor soundproofing.
Absorbs impact noise from neighbors.
Easy to install and cut, unlike cotton wool, it does not emit dangerous dust.
Serves as the main vibration isolator in floating floor systems.
With the help of Macsound, a dry floating floor system is made.
Eliminates the sound of steps and the effect of "cold floor".
When laid under a cement screed, it reduces the level of impact noise to 35 decibels.
It is used in the manufacture of a podium for drum kits.
Good thermal insulation in addition to sound insulation.
Eco-friendly.
Macsound is also used to isolate unwanted vibration and rattle from machine tools, simulators, treadmills, as well as soundproofing car hulls, yachts, ships, engine rooms, etc.
