In fairness to the OP (who has not shown us the same courtesy) there is no
link to the study itself, so we cannot know how serious it is, or to what
degree the info blurb is paraphrasing (or distorting). Doubt is cast on the
sincerity of the resume by the ending catchline about a possible solution
(closing the airport) but again this line is not clearly attributed to the
researchers (or to anyone else for that matter).

Personally, I have no difficulty in believing that continuous noise from
large, metropolitan airports has a tiring and stress-inducing effect on many
people, and could be detrimental to concentration in any school placed
nearby.

Since both schools and airports are necessary to our society and economy,
every effort should be made not to build schools next to large airports, and
those who have done so should be relocated.Such an initiative could be taken
on a "commmon sense" basis, without need to spend more millions on scientific
studies.
