I live in Layton just south-east of the flightline for HAFB. I think we probably hear the planes about 1-2 times a day, and only briefly. (Usually it is just 3 or 4 jets that fly over and then you don't hear them again for quite awhile.)
I'm an Air Force brat, so I tend to not notice them as much as some people. I remember when we lived in Fort Worth, there were the B-52's that would fly in the same circular path over and over again. Those were much louder than the F-16's that fly here. And with these ones, you don't have to worry about them flying over you repeatedly like with the larger aircraft.
If you want to have absolutely no noise from them, I would avoid Layton. I don't know how much the other towns in the area experience the flyovers, but I know Layton is effected by them daily.
Hope my ramblings helped out. It really is a great area and I think you will enjoy it. Welcome to Utah.
