ᐅ Which interior wall material and thickness provide good sound insulation?

We are currently planning a two-story single-family house with our architect, with approximately 160m² (1,722 sq ft) of living space.
The exterior walls are planned to be made of 36.5cm (14.4 inches) Poroton bricks.
When children eventually reach the relevant age, sound insulation of the interior walls will definitely become very important. Which materials have particularly good properties for this purpose? And what thickness is ideally used for these materials?

Hello,
Your structural builder is unlikely to suggest this; after all, they want to make money. A lightweight partition wall falls under the scope of drywall construction.
Best regards, BauexperteYes, I thought that afterwards as well.
But maybe he is honest (reliable) or he will offer me a good deal for an acoustic brick!
Can anyone generally comment on the sound insulation of a perforated brick with a thickness of 11.5 cm (4.5 inches)? Has anyone used this kind of brick?
The perforated brick so far planned by the builder has the following properties:
Bulk density class 0.80 kg/dm³ (50 lb/ft³)
Strength class 8
Nominal thermal conductivity 0.39 W/(m·K)
Basic allowable compressive stress 1.4 MN/m² (203 psi)
But there is no information regarding the sound insulation rating?!
Thanks and best regards,
Stefan

Best regards, BauexperteAhh – many thanks for the information, great
Hello,
I have a similar question: How does the different material mix behave if I use 42.5cm (17 inches) Liapor walls on the outside and walls with a significantly higher concrete content inside, or even a 20cm (8 inches) reinforced concrete wall purely for aesthetic reasons? Will I then have the same problem with differing coefficients of thermal expansion, etc., as with hollow bricks and sand-lime bricks?

Hello, I want to bring this thread back from the past because I’m also interested in the material mix. For the exterior walls, the offers include aerated concrete, Ytong. According to the offers, the interior walls are supposed to be made of calcium silicate blocks. Is this mix a bad choice? What wall thickness is recommended for the interior walls? For load-bearing walls, 17.5 cm (7 inches) calcium silicate blocks are offered, and for non-load-bearing walls, 11.5 cm (4.5 inches). Is the sound insulation sufficient at these specified wall thicknesses?

Peanuts7425 Apr 2016 07:45We built entirely with calcium silicate blocks, and the sound insulation is simply amazing. Noise from outside practically only comes through the windows. When they are closed and the shutters are down, you can turn the music up to almost concert volume inside the house and hardly hear anything outside.
Inside the house, for example, you can barely hear anything on the upper floor when there is party-level noise in the living room.
It is also very important not to create any sound bridges. The best blocks or insulation won’t help if you allow sound bridges...
