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.
Unless you have actually damaged your eardrums due to barotrauma, then ear popping may just be due to your body trying to relieve pressure in your ears. Pressure difference between the outside of ear drum and the Eustachian tube inside can occur while flying or climbing high altitudes or diving underwater.
