Hello everyone,
I am new to this forum, so please excuse me if I forget something 🙂
My partner and I have purchased a plot of land, but it is located in noise level zone 3, which means we have certain soundproofing requirements for the exterior walls of the bedrooms.
Does anyone have experience with this and can advise us on which type of exterior masonry we need to comply with the DIN standard? We would like to use bricks because of the indoor climate. However, do we also need to consider additional insulation? How thick would the wall be in total? Or would it be better to use a different type of masonry block?
Thank you very much and best regards,
Pia und Eike

Sand-lime brick + mineral wool insulation + facing brick, if we’re talking about the ultimate solution.Does MW refer to mineral wool?

Sound is tricky...
Don’t fall into the false assumption that the higher the insulation value of the masonry, the quieter it will be inside. Of course, there is a connection, but it won’t help if you have the best wall construction and then use uninsulated roller shutter boxes or have poorly executed connections.
So, consider whether you just want to achieve a specific calculated value or if you really want it to feel quieter. This should be discussed with the planner. If they are not experienced in this area, then bring in someone who is knowledgeable. And please make sure the installation is properly supervised.
However, too much soundproofing is not necessarily ideal either. If no outside noises are audible at all, it can feel strange. Also, noises inside the house are perceived more strongly then. Is that always desirable?

So consider whether you want to achieve a certain calculated sound insulation value or if you actually want it to feel quieter. You should discuss this with your designer. And if they aren’t experienced in this area, bring in someone who is. Also, make sure the implementation is properly supervised.

The issue is that we’re building in a noise zone (LB 3) and need to meet specific sound insulation requirements to obtain the building permit / planning permission 🙂
We also need a ventilation system accordingly.

The issue is that, since the building site is in a noise level zone (NL 3), a certain level of sound insulation is required to obtain the building permit / planning permission 🙂
Additionally, an appropriate ventilation system is needed.This can be verified through calculations. Depending on the municipality, they may accept either a rough sketch showing three sound insulation values or a proper calculation report. Some civil engineers, architects, or building services engineers do this, but it costs a bit of money.
If there is an existing sound insulation report for the building area, that is used and the relevant values for the important rooms (usually bedrooms) are applied. Every surface and its construction method is taken into account.
If done properly, it involves a detailed calculation.
However, the results are only theoretical values.
