>Perceiving a pressure difference from 6 floors of elevation does not seem legit. I generally don't notice it myself, but if you do the math (office building floor height averages ~14 feet/4.27 metres), six stories of altitude difference would change ambient air pressure by ~.3kPa. Humans can detect very small (much smaller than .3kPa) changes in air pressure, although some folks are more sensitive than others.
