Tinnitus is not a disease but a symptom of underlying causes such as ear infections, foreign objects or wax in the ear, and injury from excessive loud noise. It is the perception of sound in the ear without a corresponding external sound, or 'ringing in the ear'.
It is usually a described as a ringing noise, but has been known to take many other forms such as whining, buzzing, hissing, whistling or beeping. Tinnitus and hearing loss can be permanant, so precaution is advised, such as avoiding prolonged exposure to loud noises, typically above 70 dB. Treatment comes in many forms, some more reliable than others.
