Airline Earphone & Headset :
There is only one difference between aviation earplugs and general earplugs, that is, the function is different.
Aviation earplugs can mainly reduce noise. When the atmospheric pressure in the cabin changes, there will be a pressure difference between the inside and outside of the aircraft earplugs, and the noise reduction function is strong. . Airplane earplugs can provide an opposite resistance, so that the pressure difference in the middle ear cavity membrane can be reduced, allowing the Eustachian tube to function normally, eliminating ear pain or discomfort.
Ordinary earplugs are often used in radios, hearing aids, and can also be used for swimming to prevent water from entering the ears. Noise reduction is poor.
Extended information:
How to use aviation earplugs:
Gently pull up the upper part of the ear, align the aircraft earplugs with the ear canal, and gently rotate the earplugs to the appropriate position to ensure that the air in the ear canal is not directly connected to the atmosphere. A suggested detection method is: due to the additional noise reduction function of the aircraft earplugs, after wearing, there will be an echo when speaking.
Wear aircraft earplugs securely in each ear before takeoff, do not remove until the aircraft reaches cruising altitude, and be sure to put the earplugs on again before the aircraft begins to descend and land. Because airplane earplugs also greatly reduce the noise inside the plane.
What is an aviation headset? Why is it called an aviation headset?
Because there is no air in space, sound cannot be transmitted through the air. The principle of earphones must be transmitted through other vibration channels, that is to say, the transmission method of aviation earphones directly acts on the eardrum.
