A physiopsychological evaluation of high-rise elevator transportation effects on humans,especially those suffering from Eustachian tube obstruction and weak tympanic membranes.We determined that the number of people suffering from Eustachian tube obstruction was greater than previously expected. The leaning direction of tympanic membrane may cause increased ear pressure when riding down. Eustachian tube obstruction disturbs tympanic pressure adjustment, causes low baroreception and dizziness leaving a bad impression of the elevator. Electro-physiological measurements show that elevator transportation stimulates and tenses the subjects, especially when going down and duringperiods of rapid transport. Elevator interior also affects the subjects feelings.
