6 options for soundproofing walls using MaxSound soundproofing material.

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.

1. 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.
