Normally, swallowing causes a little click or popping sound in the ear. This occurs because a small bubble of air has entered the middle ear, up from the back of the nose. It passes through the Eustachian tube, a membrane-lined tube about the size of a pencil lead that connects the back of the nose with the middle ear.
When the pressure equalizes (the pop), whatâs basically happening is that air is being released through the middle ear to the throat via Eustachian tubes. Our ears, nose and throats are all hooked up, which is why something like yawning or chewing gum can help alleviate the situation.
