during the week i live in a flat where there is a small airport (like 10-20 take-offs/landings per day) directly next to it.
my window is maybe 400 ft away from the landing strip and i hear NOTHING. obviously, there arent very big planes around, but i cant recall hearing a plane (except for an eurofighter).
my gf had a flat in the city, in the entry lane. the planes were still 1500 to 2000 ft above the ground, but it was really loud, like really annoying.
