We have already found and reserved a plot of land. At the moment, we are gathering various quotes. However, I have come across a detail in the development plan that confuses me a bit.
Passive noise protection measures according to DIN 18005 are required. When we inquired at the local authority, we were informed that no noise assessment report has been prepared. The noise levels exceed the limit specified in the standard by up to 5 dB(A).
The plot is located next to a country road. The house façade will be approximately 17 m (55 feet) away from the road. A municipal earth berm has also already been built.
The house will have triple-glazed windows and corresponding insulation according to the KfW 55 energy standard. There will also be electric shutters.
How can I find out exactly which measures are required? Or are these measures already sufficient?
I would appreciate any advice.
Best regards

Very important: soundproof windows, at least class 4. Triple glazing is worse than double glazing. Thermal insulation always comes at the expense of sound insulation.
If possible, avoid Ytong houses. Unfilled Poroton blocks are sufficient, but filled blocks are better. No decentralized ventilation or window frame vents.

This is not understandable to me I’m not an acoustics expert, but you can look it up in the manufacturers’ charts. Possible explanation: with double glazing, the panes are thicker and overall have more mass.B
Burn3r19856 Nov 2019 09:20Thank you for the explanations so far. However, my question is: who ultimately checks whether we comply with the passive requirements from the development plan? The municipality has not provided a detailed list of requirements that we must follow. The only specification is that the DIN standard may be exceeded by up to 5 dB.
The district road is approximately 17 meters (55 feet) away. An embankment made of earth and trees was created by the city several years ago.
The district road connects two villages. The village where we are building has 788 inhabitants. The noise level (we have visited the site several times) is actually very low and not comparable at all to our current living situation.

A quick search shows that this claim doesn’t hold up. It seems that triple-glazed windows do not provide significantly better sound insulation than double-glazed ones. When fitted with appropriate films, the sound insulation improves equally for both types, since usually only the outer two panes are laminated.
