I also live in the city - and just measured on Google Earth. From our house to the railway line (S-Bahn and freight trains) it is 250m. However, the area is completely built up with two-story buildings. We don’t really notice the railway line. At night with the window open you can hear the trains quietly, but thanks to controlled residential ventilation, this doesn’t really happen often. The visual flight approach route (i.e. Cessna and co.) from Nuremberg Airport goes directly over the house. You can hear them, but there are very few. My daughter (2) is always happy about the rescue helicopter, which usually flies quite low and flashes so nicely [emoji]. I am a glider pilot myself - if you tell me the airfield, I can check how large the local club is and whether it is more gliding or powered flight. My parents live about 4.5 km northeast of a compost yard. You can perceive a slight smell on about 3-5 days a year. A school friend of mine lived 3 km east, and there the smell was noticeably more frequent and sometimes quite strong. In Germany, our main wind directions are EAST and WEST, with west wind dominating at about 60% and often being stronger than east wind. Especially in stronger wind conditions, northwest is also clearly more likely than southwest. Pure north wind is relatively rare; pure south wind occurs in southern Germany during Föhn.
