What do you think the loudest airport is in the United States I guess per capita of loud aircraft to quiet aircraft if you get what I am trying to ask... also the quietest. Note- NOT including military movements at airport if airport shares with air base.
In other words if you had a somewhat sensitive car alarm how often would it go off with planes taking off.
I might say DTW is the loudest airport in the US (tie with MSP) because of all of those NW DC-9s. At the south employee lot at DTW, everytime a DC-9 takes off it sets off about 20 car alarms. On top of that, there are still quite a few 727s and an occasional SW 732 taking off too. The DC-10s and 744s have a real rumble too that can set off car alarms. I have heard car alarms go off when a 744 takes off on runway 22L, but the car is parked under 21R takeoff.
The quietest I would say probably is John Wayne in Orange County with all of their noise restrictions.
