Tinnitus
Description
Tinnitus (from Lat. tinnīre — "to tinkle or ring like a bell") — ringing or tinnitus without an external acoustic stimulus. This sensation can be characterized by patients as a hum, hissing, whistling, ringing, the noise of falling water, the chirping of grasshoppers.
Studies conducted in Europe and North America have shown that about 1/3 of the adult population has experienced tinnitus at least once. It is extremely rare for children to complain about tinnitus and almost never for patients with congenital deafness. Tinnitus is not a mandatory symptom of any disease, however, it is known that up to 85% of patients suffering from this ailment have a registered hearing loss in the range of 250-8000 Hz.
Tinnitus can be caused by taking a number of medications or drug interactions.
