ᐅ Are filled or hollow bricks more effective for interior sound insulation?

Hello everyone,
We are planning to build a single-family house using hollow bricks with a thickness of 36.5 cm (14.4 inches) (Thermoplan S8). They provide good thermal insulation but are probably less effective for soundproofing compared to similar solid bricks. We live in a rural area on a side street, so external noise is not a major concern.
For the interior walls on the upper floor (bedrooms and children’s rooms), we plan to use bricks with a higher bulk density class (1.2) because sound insulation inside the house is important to us.
However, I keep reading that the exterior wall bricks also affect soundproofing within the house (sound transmission through the exterior walls into the other floor). Is that really the case? I haven’t found any information about this on the manufacturers’ websites.
Does anyone have knowledge or experience regarding this?
I would appreciate any feedback!

Acoustic insulation with lightweight concrete blocks achieves 63 dB with a 24cm (9.5 inch) block at density class 2, which is almost twice the soundproofing compared to the best brick.I live in a lightweight concrete block apartment building and have no complaints. HoisleBauer22 schrieb:
Can you explain a bit more what this is and which manufacturers offer it?Look in the lightweight concrete block sector at the usual suspects: KLB (climate lightweight block), Riffer Bisotherm, Meurin, Ehl, ... HoisleBauer22 schrieb:
If I take 11.5cm (4.5 inch) wall thickness times a density factor of 1.4, I get the value “16.1” (crazy calculation, I know...).I couldn’t have said it better :-)https://www.instagram.com/11antgmxde/

Please make sure to include the windows as well, especially to the original poster. Our brick wall has a sound insulation rating of 43 dB, but unfortunately, the windows only provide 32 dB. We didn’t pay enough attention to that. I have already had the bedroom window panes replaced, and now the floor-to-ceiling windows in the living and dining rooms will be next. It’s frustrating. But since the neighbor just announced they’re expecting their fifth child, and their sloped driveway (I’m just saying, it’s perfect for a ride-on toy) runs right along the boundary, I have to bite the bullet, or my nerves won’t hold up.
