Tinnitus
Pronunciation: TIN-ih-tus or tih-NY-tus
The perception of sound—commonly described as ringing, buzzing, or hissing—in the absence of an external acoustic stimulus, documented as both a symptom and a clinical condition.
Full Definition
Tinnitus is a phantom auditory percept characterised by ringing, buzzing, hissing, clicking, roaring, or other sounds that have no identifiable external source. It may be subjective (heard only by the patient) or, rarely, objective (audible to the examiner via auscultation). Tinnitus is classified by duration (acute vs. chronic), laterality (unilateral vs. bilateral), pitch (tonal vs. noise-like), and impact on quality of life. Audiological assessment of tinnitus includes pitch and loudness matching, minimum masking levels, and validated questionnaires such as the Tinnitus Handicap Inventory. Editors must ensure correct spelling ('tinnitus,' not 'tinitus') and should note that the pronunciation varies between British and American usage.
Usage
Usage note: One of the most frequently misspelled audiological terms; always verify double-n. Do not conflate subjective tinnitus (the predominant form) with objective tinnitus without specifying the distinction.
