what is it supposed to mean when your ears ring
http://georgiahealthinfo.gov/cms/node/105663. When someone has ringing in the ears, it is called tinnitus.. The definition of tinnitus is perceiving a sound in the ears or head when there is not an actual external source for this sound. Put simply, tinnitus is the perception of a non-existing sound. A person hears the ringing in his or her ears or head, but no one else does.
