Yeah, with this crumb cookie, every day I’m afraid my house will collapse.
You’ve never held the stone in your hand, have you? But you just had to make a stupid remark!

Calcium silicate brick is recognized and proven in practice for good sound insulation due to its mass and high bulk densities. However, the best soundproofing is of no use – for example in an apartment partition wall – if the adjoining components negate it. It is proven that sound transmission occurs through the separating components and through the adjoining components, such as ceilings, interior and exterior walls.

Applied to the exterior walls of a detached single-family house, are you saying that sand-lime brick is the material of choice when it comes to sound insulation?

No! There are as many opinions as there are building materials. If the stone existed, only that would be used. I myself am a fan of aerated concrete. That will surely call up 10 "opponents" again right away. Poroton also has its justification and, like many things, advantages and disadvantages. Since it was explicitly about soundproofing here, sand-lime brick automatically comes into play. That also has disadvantages. So it depends on the specific situation! I recently supervised the house construction for a then good friend. She wanted interior walls made of drywall (because that's apparently how it's done). I convinced her to use 11.5 cm interior walls made of aerated concrete and she thinks it's good today. There is no opinion! And this, please, should also be taken to heart by the co-authors here and not tear each other apart!!!

yes, anything that has a high surface weight (mass per m2 of exterior surface) also insulates well against sound.

From this perspective, concrete is also very good. Or "classic" bricks without crumb filling.

You can top this off completely with a double-shell construction with an air gap or mineral wool in between; even a three cm gap provides an extra 12 dB. If you make the gap wider, it doesn’t change anymore, but you can then put in more insulation.

Again, the wall is relatively uninteresting. Instead, devote your planning energy to the windows and [Anachlussfugen].
