Chris_HLHello everyone,
My partner and I have been searching for a plot of land for our new home for quite some time. There is a new development area that meets our criteria in terms of central location, affordability, and size, but unfortunately it lies between two highways (approximately 300m (985 feet) away with noise barriers to the northeast and 600m (1,970 feet) to the northwest – latitude: 53.844413 | longitude: 10.597826).
The local authority commissioned a noise protection study. Measurements were taken at a height of 4m (13 feet) with a 1x1m (3x3 feet) grid. The results show that, in the undeveloped condition, the guideline values according to DIN 18005/2 (55 dBA / 45 dBA) are exceeded, but the daytime limit of 59 dBA for residential areas is still met. At night, the limit of 49 dBA is exceeded, so it is recommended that bedrooms be positioned on the side away from the noise. Further noise protection measures were considered not useful according to the study, as the noise is described as diffuse.
Do you have experience with how noise exposure changes once the area is developed, or how this level of noise might feel?
Can you, from your own experience, assess how reasonable these noise limits are? We have no sense of how much the noise might bother us in the future or affect our health.
We look forward to your responses and assessments.
Best regards and thank you,
Chris

But what you are describing is like saying, “give me the benefits (central location) without the downsides (please no noise).”
I live myself in the flight path of DUS airport, with planes flying at about 1,200 meters (3,940 feet) altitude and a horizontal distance of around 400–600 meters (1,310–1,970 feet), depending on the wind direction. About 40% of the approaches come from our direction, mostly in summer.
It’s not pleasant in the garden, but you do get used to some of it over time.

toxicmolotof10 Mar 2017 18:30I would like to add two more points to my response.
Before moving into our house, I lived in a rental apartment. The distance to the highway (no speed limit) was just under 1000 meters (3300 feet). When the wind was "favorable," you could basically not hear it, but when the wind was "unfavorable" and the window was open, you could hear a noise similar to the sound of the sea... well, almost. However, what you always heard, as long as you were awake and the window was open, were louder-than-average cars and motorcycles. So besides the constant background noise (which was measured at your place), there are still noise peaks. They generally won’t wake you up during sleep, but you do perceive them consciously.
And the second point I want to mention: with every doubling of the distance, the sound level decreases by 6 dB. Just some information for reference.

Enter the coordinates into Google... I’m surprised by what "central location" can mean nowadays. Apparently, it refers to the distance to the nearest highway interchange, as the development area is located almost directly underneath it, and there isn’t much around.
The village has 1,500 residents (plus 80,000 passersby per day).
What is the asking price for this piece of land?

toxicmolotof10 Mar 2017 21:37After initially landing near Somalia, I swapped the coordinates.
It is really only a 12-minute drive to Lübeck Central Station, so it’s not exactly out in the countryside, but I wouldn’t call it central either.
This kind of decision has to be made individually. Here (Rhineland, outer commuter belt of Düsseldorf) I know many more people living within a 300m (330 yards) strip along highways than live in the entire village there. So, it’s manageable.
