A build-up of earwax can cause dulled hearing and sometimes other symptoms. Earwax can usually be easily removed. Earwax is a build-up of dead cells, hair, foreign material such as dust, and cerumen. Cerumen is the natural wax produced by glands in the ear. It forms a protective coating of the skin in the ear canal. Small amounts are made all the time. Flakes or crusts of earwax break off and fall out of the ear from time to time.
The most common triggers of plugged ears are: 1  Ear Wax. 2  Blocked nose. 3  Cold. 4  Sinus infection. 5  Allergy. 6  Accumulation of water within the ear. 7  Changes in atmospheric pressure while travelling in an airplane. 8  Blockage in the Eustachian tubes.
