From someone who experiences this ringing every day too. I tried to shut it down, make it quiet, disown it as 'normal to me', but in the end, I just had to accept it as part of my most daily of daily things, just like the glasses I wear. Only this acceptance alone has made it possible for me to keep on enduring that sound without too much of a bother, since I've noticed it's probably not going to go away for ever, until death do us part :D
