Classification and epidemiology of tinnitus

Tinnitus affects up to 30% of the adult population, with 6% of these individuals reporting incapacitating symptoms. Although a universal classification system for tinnitus has not yet been realized, there are several factors that can be identified to assist in further differentiating the etiology in some patients. A standardized classification system for tinnitus is a vital component of the common language that must be developed to better define the etiology and treatment for patients.
