tinnitus
Pronunciation: TIN-ih-tus or tin-EYE-tus
Perception of sound (ringing, buzzing, hissing) in the absence of external acoustic stimulation.
Full Definition
Tinnitus is the subjective perception of sound when no external sound source is present, commonly described as ringing, buzzing, hissing, or clicking in the ears. It can be continuous or intermittent, unilateral or bilateral, and may significantly impact quality of life. Tinnitus is often associated with hearing loss, noise exposure, or ototoxic medications. Clinical documentation must distinguish between subjective tinnitus (heard only by the patient) and objective tinnitus (audible to the examiner), though the latter is rare.
Usage
Usage note: Both pronunciations are acceptable. Always singular in form; use 'tinnitus symptoms' for plural reference.
