Sanohra

Hearing protection Fly adults

SANOHRA fly  was developed specifically with the aim of protecting the ear from rapid and strong changes in air pressure, such as those that occur in airplanes or amountain runway . Used in good time before landing or descending, the hearing protector forms a small chamber in the ear canal in front of the eardrum. A special high-precision filter delays the increase in air pressure in this small chamber.

Even if the Eustachian tube can only perform an active opening for pressure equalisation to the middle ear in a delayed or restricted manner, the buffer effect in the chamber does not cause a painful bulging of the eardrum.

This relatively simple principle requires a highly precise filter that limits the air flow into the chamber so extremely that the desired buffer effect can actually occur.

This distinguishes SANOHRA fly from simple noise protection plugs, which are unfortunately also offered by some manufacturers with the indication for use when flying, without having any effect against changes in air pressure.

 

Application

If you have also experienced ear pressure and ear pain during take-off and climb, we recommend that you insert the hearing protection before take-off and do not remove it until approx. 30 minutes after take-off. Only then is the cruising altitude normally reached and the pressure conditions in the cabin no longer change until the descent begins. By the way, for short-haul flights of less than 1 1/2 hours, we recommend wearing SANOHRA fly for the entire flight, especially as the hearing protection also has a noise-insulating effect.

45 minutes before the planned landing, you should definitely insert the earplugs because the air pressure in the cabin rises again quickly as soon as the aircraft leaves the cruising altitude and starts to descend. We recommend that you do not take out SANORA fly until you reach the airport building, to give the eustachian tubes enough time to equalise the pressure.

Note

Almost every air passenger has suffered it at some point: an unpleasant feeling of pressure or even pain in the ear when the plane lands. Sometimes hearing is also impaired for days after the flight.

At cruising altitude, the air pressure in the aircraft cabin is only equivalent to that on a mountain around 2000 metres above sea level. During landing, the air pressure in the cabin rises again very quickly.

In this situation, the ear must also react. The Eustachian tube, a tube-like connection between the nasopharynx and the middle ear, must ensure that the air pressure in the middle ear also rises again through a so-called active opening. If this does not happen quickly enough, a pain-inducing bulging of the eardrum will occur.
