<p>Devices for suppressing ear troubles produced by pressure variations of the environmental atmosphere, by providing a certain air vaccum. The device according to the invention is essentially characterized in that it comprises at least two ends (1) to be associated to the auditory meatus (2) of a person, each end comprising a traversing orifice (3), and means (9, 11, 14, 15, 11 bis) to control a fluid circulation in the traversing orifice so as to modulate the fluid pressure inside the auditory meatus as a function of the pressure of the atmosphere where the person is. Application: particularly for the suppression of ear troubles during airplane travels.</p> |
