Hello!
I would like to know if anyone has experience working with soundproof drywall. How has it worked out for you? Is it really worth buying, meaning, does it make a noticeable difference compared to just using double layers of regular drywall?
I’m currently considering whether it’s worth investing in.

@Torsten-HBS: The key factor is definitely how the drywall partition is constructed. Is it just gypsum board? With OSB? At least for sound insulation and fastening purposes, I wouldn’t want to do without OSB panels or an alternative. It shouldn’t make a significant difference compared to a brick wall.
In the brochure I received from Rigips Austria, a brick wall is compared with a standard single-layer drywall and a wall with Duo'Tech panels. The starting point is always the same wall thickness. The brick wall offers 42 dB, the single-layer drywall 54 dB, and the double-layer drywall 61 dB sound insulation.
The advantages mentioned are that the double-layer wall can be constructed faster than the brick wall, is more cost-effective, and also lighter.
So such a wall can not only keep up but also offer additional benefits.

A brick wall made with 100mm (4 inches) hollow bricks and plastered on both sides weighs about 114kg/m² (23.4 lbs/ft²).
The double drywall partition weighs only about 50kg/m² (10.2 lbs/ft²), so it is similar in weight to a wall fitted with two layers of single drywall boards.
An almost 20 dB difference is quite significant. The 7 dB difference compared to the standard double-layer drywall wall may not seem much at first glance, but that’s why I tried to explain that a 10 dB difference corresponds to halving the perceived loudness. MayrCh explained it even better.
