The Eustachian Tube is also called the ear tube or the auditory tube. This is the connection between the throat region and the ear. You can open it by chewing, swallowing or conscious pressure compensation. You perceive this as a light “crackling” in the ear.
Especially when you have a cold, the Eustachian tube is often swollen and the pressure compensation can only take place in part. This is why you should not go diving when you have a cold. Because by doing so, the risk of a barotrauma is increased.
