ᐅ Hollow bricks and soundproofing – looking for experiences

Hello,
we are planning to build our house using unfilled Unipor bricks. Since the plot is in a quiet location, we had no concerns about sound insulation so far. However, a construction company advised me against this because internal noise could also be a problem.
Does anyone have a house built with unfilled bricks? If yes, which bricks and what thermal insulation value do they have? Are there any issues with sound insulation?
Thank you very much!

We used these bricks, but next time I would definitely choose sand-lime bricks for the interior walls and insulated exterior bricks, for example filled with mineral wool. However, it depends on how sensitive you are, and it also costs money—our general contractor quoted 7000 euros just for insulated exterior bricks. TV sound isn’t really a problem, even with a home theater system. And noise hardly transfers through the exterior walls at all... but you will still hear the teenager’s music. If you decide on standard interior bricks, be especially careful with the bathrooms: make sure the walls are thick enough, and if possible, avoid having the pipes for toilets or other fixtures adjacent to the children’s room. Otherwise, you might wake the little one.
With a 24 cm (9.5 inches) wall and insulated pipes, this shouldn’t be a problem even with bricks.
What’s important is the overall concept. If you use CPL doors for the interior or windows with poor sound insulation, you won’t gain much. Everything has to work together.

There are also hollow bricks, and I am not impressed at all. A simple test: tap on the hollow bricks and compare it to filled bricks. There is a huge difference. With hollow bricks, even a key rattling on an outdoor water tap can be heard inside the house because of the wind. They are that sensitive!
Still, many people build with them, but lemmings also jump in groups...

Try tapping on the hollow brick cavity. Yes, of course, they naturally act as resonators.

A few basic things if sound insulation is important to you.
Plan rooms so that a children's bedroom is never next to the main bedroom.
If using mechanical ventilation with heat recovery, then a transfer grille in the door frame or the door closed and an exhaust duct for each room.
Sleeves for cables or pipes should be insulated, etc.
My next house will be made of sand-lime brick, although many people have concerns about thermal insulation with this material.
Is it possible to use sand-lime brick with brick cladding without external thermal insulation composite system (ETICS) / external wall insulation?

Just take a look at the sound insulation values and then choose something where everything fits together...
I’m not a big fan of external thermal insulation composite systems (ETICS), I just don’t like them... so I prefer bricks filled with perlite or mineral wool, although the latter isn’t very environmentally friendly either...
I’m very sensitive to annoying noises, but at our place the weak point is the windows before the brickwork even comes into play...
For doors, I can only recommend solid core... amazing...
