Special ear plugs can help air travelers who suffer from ear pain when flying. An integrated filter ensures that the air pressure in front of the eardrum much slower increases than in the aircraft cabin. Thus, the Eustachian tube promote the necessary active opening to the middle ear and with limited function.
Decisive for the schmerzverhindernde effect is the precise operation of the filter. The company INNOSAN GmbH has developed these hearing protectors, which features a high-precision pressure regulator which can regulate the extremely low air volumes accurately. SANOHRA fly ear plugs was developed in Germany and is manufactured here.
The ENT University Hospital Charité in Berlin has studies with subjects who reported a history of pressure equalization problems in rapid changes in ambient pressure performed.
Here, the study participants were exposed in a pressure chamber conditions that correspond to those on the landing approach. When using SANOHRA fly ear plugs the pressure changes were perceived by participants as more pleasant.
Pressure regulating ear plugs tested in a pressure chamber: In June 2010, the scientific study of Charité Berlin on the subject was
