ᐅ Building Material Choice: Brick or Aerated Concrete – Acoustic Assessment Considerations

Hello,
we are currently deciding on the building material... We have been offered both brick and aerated concrete, with no price difference according to what we were told, and the company uses both materials about 60/40%. There have been various trends, sometimes more brick, sometimes more aerated concrete.
The plan is to build a single-family house of 140-150 sqm (1500-1600 sq ft), KfW 40 standard (if eligible for subsidies, otherwise 55), monolithic, with a centralized ventilation system and an air-to-water heat pump. The shell construction will be managed by ourselves.
I have read that aerated concrete offers slightly better insulation, while brick is preferable for soundproofing. Even when asking several homeowners, you get 15 opinions from 10 people. A secondary school is being built nearby, and a state road runs about 300 m (980 ft) away. I have attached excerpts from the acoustic report.
Are there advantages to one of these materials in this situation, or can I basically just “flip a coin”?
Thanks for your opinions

I noticed on the plans that some interior walls are 11cm (4.3 inches) thick – is that too thin or too noisy if made with aerated concrete?No.Seb_Opf schrieb:
Another question: when the house is eventually demolished, is aerated concrete considered hazardous waste and more expensive to dispose of?Yes.By the way, my stone mantra also applies to interior walls ;-)

My opinion (known as the 11ant stone mantra) is this: it’s better to choose the material of your second option and the builder of your first choice the other way around (or, as mathematicians say, do multiplication before addition).11ant schrieb:
You can find my collected thoughts on this topic by searching for "11ant Steinemantra." Simply put, it says: "choose the wall construction that your builder is better at." If they offer construction A:B in a 60:40 ratio, you have a free choice; if it’s 90:10, definitely forget about option B. Construction defects are created many times more in the workmanship than in the material.Or you can simply read "The 11ant Stone Mantra" on the Baulotse blog (externally searchable).https://www.instagram.com/11antgmxde/
