Why do those people with hypertension choose to live under the
flight-path of neighborhood airports? Is it because that is the only
location their financial means affords them?

Airplane Noise Linked To High Blood Pressure

It may be music to the ears of some, but airplane noise may be
hard on the heart. A Swedish study suggests that men who live near
airports have a greater risk of developing high blood pressure
than those who live in quieter neighborhoods. "It is thought that
aircraft noise causes stress problems when it interferes with
people's ability to think, relax or sleep, for example," study
organizer Dr. Mats Rosenlund of the Karolinska Institute in
Stockholm told Reuters Health. The study followed 2,000 men, who
didn’t have high blood pressure, for 10 years and found that the
20 percent of study subjects who lived in the noisiest area were
19 percent more likely to develop it. The study took into account
lifestyle factors like obesity, exercise and eating habits.
Rosenlund cautioned that the study does not prove that airplane
noise causes high blood pressure but he did say it was consistent
with other studies that draw a link between blood pressure and
noise.

Is it time for real estate sellers of properties impacted by airport
noise to require buyers to attest to their knowledge and assent to
noise?
