Charité Study
The effectiveness of FlightSafe ear plugs was scientifically verified in a pressure chamber in a study at the ENT clinic of Charité in central Berlin with a group of test subjects who routinely suffered from ear pain during flights (airplane ears). It was proven that the ear pain caused by changes in pressure, such as those arising in the aircraft cabins reduced significantly (Jumah et al., Pressure regulating ear plug testing in pressure chamber, Aviation, Space and Environmental Medicine, June 2010).
