I would think if you had lived by an airport for any length of time you would be familiar with many sounds and know when you were hearing something out of the ordinary even for that location.
I would say so too.....However, there are many sounds around us that we've gotten used to and just normally block out. For example, I live about a half mile away from a major 8 lane highway that is not an expressway, where the speed limit is 50 mph.
I can wake up in the morning at about 5:30 a.m. and lie in bed in the spring and listen to the birds chirping. Nothing wrong with that except this is spring and those birds haven't been around all winter and that's why they're now noticeable.
Then as I explore with my hearing, I suddenly pick up the distant low moan of the highway traffic which goes on 24/7 and until then, has been transparent since my mind has filtered it out. If I were to have a visiter who lives out in the country stop by, they would probably notice that noize right away then forget about it as they get used to it.....
Another extreme example would be someone who lives near railroad tracks and has gotten used to the daily rumble of the trains. To us dropping by, we would probably say to him how the heck can you put up with that noise......
