I've had tinnitus for 40 years, accompanied by deafness in one ear, due to inner ear damage caused by getting Mumps when I was 13. If I focus on it, it's really loud - I can easily hear it over a loud pub environment, and it's there all the time. But the brain is amazingly adaptive - if I don't focus on it, it doesn't annoy me, and I forget it is there.
