What is Tinnitus and How Many People Have It?
Tinnitus is the term for the perception of sound when no external
sound is present. It is often referred to as "ringing
in the ears," although some people hear hissing, roaring,
whistling, chirping, or clicking. Tinnitus can be intermittent
or constant, with single or multiple tones. Its' perceived
volume can range from very soft to extremely loud.
HOW MANY PEOPLE HAVE TINNITUS?
50 million Americans experience tinnitus to some degree. Of
these, about 12 million have tinnitus which is severe enough
to seek medical attention. Of those, about two million patients
are so seriously debilitated by their tinnitus, they cannot
function on a "normal," day-to-day basis.
