Tinnitus is the perception of ringing, buzzing, humming, hissing, or another sound when there is no corresponding external sound source.
Tinnitus can be temporary or persistent and may occur in one or both ears. It can be associated with noise exposure, hearing loss, ear disorders, certain medications, and other conditions, although sometimes no single cause can be identified.
Tinnitus is a symptom rather than a disease by itself. A brief episode after loud noise can resolve, whereas persistent or recurrent tinnitus may warrant medical assessment, particularly when it occurs with sudden hearing loss, significant dizziness, neurological symptoms, or other concerning features.
For some people, tinnitus is mild and intermittent; for others, it can interfere substantially with concentration, sleep, or quality of life.
QUICK FACT
Tinnitus is a symptom rather than a single disease, and the sound experienced can vary considerably between individuals.
COMMONLY CONFUSED WITH
- Hearing loss: reduced ability to hear sounds; tinnitus can occur with or without measurable hearing loss.
- Temporary ringing after loud noise: a form of tinnitus that may resolve after the exposure ends.
