Tinnitus-derived from the Latin “tinnire” meaning “to ring” is a perceived ringing, buzzing, or hissing in the ear(s) or around the head-which has multiple etiologies and is sometimes idiopathic. As of 2009 in the United States, approximately 50 million Americans were affected for six months or greater, while a United Kingdom study in 2000 reported a 10% prevalence in the adult population. Tinnitus may vary widely with regard to pitch, loudness, description of sound, special localization, and temporal pattern. Most often, tinnitus is associated with other aural symptoms, such as hearing loss and hyperacusis. Tinnitus may result in sleep disturbances, work impairments, and distress. The severity varies within this cohort of chronic sufferers, with some unable to fulϐill daily activities. Though tinnitus is more likely to affect adults and the incidence increases with age, children can experience tinnitus as well. Males are more likely to suffer as are individuals who smoke.
