This must all be highly subjective. I used to live directly beneath a
heavily used visual approach to one of the nation's largest airports,
and I don't recall aircraft noise ever being objectionable to me. At
the same time, the upscale retirement community only about 300 feet
away constantly complained about noise, so much so that I once wrote
to the city to tell them that not everyone in the flight path found
the noise bothersome--indeed, I really had to pay attentiont to notice
it at all.

Of course, if you're so close that the noise interferes with
conversation or some other important activity, that's different. Some
of my relatives live so near KSAN that I was afraid to visit them when
I was little, because the loud rumbling that they heard every few
minutes as jet aircraft wound up for take-off felt like an earthquake
to me, and I was afraid we would all slide into the ocean.
