Researchers use electrodes to record data relating to the study while test subject Christoph Helfenbein is asleep in the hypobaric chamber. The chamber is kept at the same atmospheric pressure as would be experienced at an altitude of about 2400 metres – the pressure maintained inside an aircraft cabin once it climbs above this height. Typical sounds of an aircraft interior are played through loudspeakers. Scientists at DLR are conducting research for the first time into how well pilots and crewmembers are able to rest and relax on board an aircraft.
