Just wanted to add a little more to what Tiffani said and emphasize that you need to consult your doctor who will most likely refer you to an ENT:
/tÉªË?naÉªtÉ?s/ or /Ë?tÉªnÉªtÉ?s/,
 from the
Latin word for "
) is the perception of sound within the human ear in the absence of corresponding external sound.
Tinnitus can be perceived in one or both ears or in the head. It is usually described as a ringing noise, but in some patients it takes the form of a high pitched whining, buzzing, hissing, humming, or whistling sound, or as ticking, clicking, roaring, "crickets" or "tree frogs" or "
locusts", tunes, songs, or beeping.
 It has also been described as a "wooshing" sound, as of wind or waves.
. Tinnitus can be intermittent or it can be continuous. In the latter case, this "phantom" sound can create great distress in the sufferer.
Tinnitus is not itself a disease but a
symptom resulting from a range of underlying causes. Causes include ear infections, foreign objects or wax in the ear, nose allergies that prevent (or induce) fluid drain and cause wax build-up, and injury from loud noises. Tinnitus is also a side-effect of some oral medications, such as
aspirin, and may also result from an abnormally low level of
serotonin activity. It is also a classical side effect of
Quinidine, a Class IA anti-arrhythmic. In many cases, however, no underlying physical cause can be identified.
The sound perceived may range from a quiet background noise to one that can be heard even over loud external sounds. The term "tinnitus" usually refers to more severe cases. Heller and Bergman (1953) conducted a study of 80 tinnitus-free university students placed in an
anechoic chamber and found that 93% reported hearing a buzzing, pulsing or whistling sound. Cohort studies have demonstrated that damage to hearing (among other
health effects) from unnatural levels of noise exposure is very widespread in industrialized countries.
Because tinnitus is often defined as a subjective
phenomenon, it is difficult to measure using objective tests, such as by comparison to noise of known frequency and intensity, as in an audiometric test. The condition is often rated clinically on a simple scale from "slight" to "catastrophic" according to the practical difficulties it imposes, such as interference with sleep, quiet activities, or normal daily activities.
 For research purposes, the more elaborate Tinnitus Handicap Inventory is often used.
