Changing altitudes causes pressure variations in the atmosphere that consequently affect the air pressure in the middle ear. The Eustachian tube which connects the middle ear to the nose and throat acts like a pressure valve, it opens and closes to equalize pressure on both sides of the eardrum. When the Eustachian tube opens, one may feel or even hear a pop inside the ear. Individuals with sensitive ears or suffering from conductive hearing impairments will find this process a painful one.
Airplane earplugs are designed to facilitate the process of pressure equalization in the middle ear. They are reusable silicone earplugs fitted with a filter or a tiny hole that regulate the air pressure forced on the eardrum. Hence, allowing more time for the Eustachian tube to perform its function of equalizing pressure. The result is a painless, smooth change of altitude every single time. When used for the duration of the flight, these earplugs will also block the exhausting airplane noise experienced throughout the flight. Using airplane earplugs will make your travelling experience a pleasant one.
