is not a disease, but a noise that heard within the human ear in the absence of
corresponding external sound. It is the result of a wide range of different
causes which include various kinds
of ear infections, wax in the ear, or may be the result of some kinds of nose
allergies that may cause wax build-up by preventing the fluid draining. But in
common cases tinnitus is a noise-induced hearing loss and can be a cause of natural
hearing impairment as a sign of aging, side-effect of some kind of medications
and side-effect of genetic hearing losses.
