Ear fullness can have other causes including: 1  Acoustic neuroma (benign tumor of the nerve connecting the inner ear to the brain)  Barotrauma (effects caused by sudden or extreme changes in air pressure)
Just like you can have a spasm or twitch in your eye muscles -- or indeed any muscle -- these muscles cause a unique sound sensation in the ear when they repeatedly twitch with high frequency. The plugging/unplugging sensation is likely the Eustachian tube, which controls the pressure in the ear, opening and closing.
