Tinnitus, "ringing ears" or ear noise is a phenomenon of the nervous system connected to the ear, characterised by perception of a ringing, beating or roaring sound (often perceived as sinusoidal) with no external source. According to the American Tinnitus Association, tinnitus is pronounced two distinctly different ways, with both being acceptable: ti-NIGHT-us, or TIN-it-us.
Explanation
Tinnitus can be objective (the sound, e.g., a bruit, can be perceived by a clinician) or subjective (perceived only by the patient). The sound may be a quiet background noise, or loud enough to drown out all outside sounds. While the term 'tinnitus' usually refers to more severe cases, a 1953 Heller and Bergman found in a study of 80 tinnitus-free university students that 93% reported hearing a buzzing, pulsing or whistling sound. An increasing number of young people are developing tinnitus; as a result, it is sometimes referred to as "the club disease" as many people experience tinnitus or "ringing ears" after attending loud clubs or concerts or using personal stereos at unsafe volumes.
