Pressure regulating ear plugs against earache when flying

Around half of all air passengers know the uncomfortable feeling of pressure in the ear, or even pain that occurs during landing. Sometimes these problems last for days after the flight and so spoil the beautiful vacation days or affect an important business appointment.

So act SANOHRA fly ear plugs

After reaching cruising level the cabin pressure corresponds to an air pressure on a mountain to approximately 2000 meters above sea level. During descent and landing the air pressure in the cabin rises again very quickly. In this situation, the ear must respond. The Eustachian tube connecting the nasopharynx with the middle ear must ensure through a so-called active opening that the air pressure in the middle ear rises too. If this does not happen fast enough, there is a nociceptive curvature of the eardrum. Used 45 minutes before landing SANOHRA fly ear plugs form a tiny pressure chamber in front of the ear drum. The ear plugs for flying, equipped with a specially designed micro-filter, ensure that the air pressure in the ear canal increases much slower than in the cabin.

How To Use

Before take off

If you have felt pressure in the ear and pain even at the start of the flight and during ascent we recommend inserting the ear protection before the start and to remove it only after approx. 30 minutes after the start of the flight. The pressure conditions in the cabin normally do not change at cruising altitude till the aircraft begins to descend. During flights of less than an hour and half duration, we recommend wearing SANOHRA fly ear plugs during the entire flight, especially since the ear protection additionally works to reduce noise.

Before landing

You should always insert the ear plugs 45 minutes before the planned landing because the air pressure in the cabin rises rapidly as soon the aircraft leaves cruising altitude and starts to descend. We recommend removing SANORA fly only on reaching the airport building, to allow the Eustachian tubes sufficient time to equalise the pressure.

Children in particular, often suffer from pain in the ears while landing. The little ones receive a very special present, to make holiday travel not just pain-free but entertaining as well.

Demonstrating the effectiveness of SANOHRA fly ear plugs



The effectiveness of SANOHRA fly ear plugs were detected in the Charité in Berlin and in a large study of more than 500 passengers from TUIfly:

  • 90% of all subjects reported a significant relief of symptoms.
  • 80% of them were completely pain-free (group A)
  • over 80% of subjects would recommend SANOHRA fly ear plugs to their friends.

Charité Study

The effectiveness of SANOHRA fly 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).

Leibniz University Hannover - Study

A user acceptance study and a practical test were conducted on over 500 passengers by the Institute for Marketing and Management of the Leibniz University, Hannover, for Hannover Airport, TUI and Innosan GmbH:

• Over 90% of the participants reported an improvement in their condition

• Around 80% of the user group with medium severity ear pain had no pain at all

• Over 80% of all tested persons stated that they would recommend SANOHRA fly to their friends
