Definition Of Tinnitus
Tinnitus is defined as the noise in the ears or head without external source. Noise, discomfort is described as a whistle, clang, buzz, or hiss. It is a perceived sense individually, which can be continuous or intermittent, and its volume depends on the ambient noise that is heard with greater intensity at night before sleep, or quiet conditions. The noise is heard by one ear, both or the middle of the head, and can be synchronized with the heartbeat.

Epidemiology Of Tinnitus
Tinnitus is not a disease but a symptom that occurs frequently, affecting 17% of the world population. (44 million U.S.) for most people is nothing more than an annoyance, but in severe cases alters the quality of life in circumstances such as concentration and sleep, this population is estimated at 4%. It is reported that tinnitus is associated with Hyperacusis (is decreased sound tolerance) in approximately 40%.

It affects any age group, especially those exposed to very high noise, not excluding the aging as one of their associations.
