And I have a pretty bad case. Now I am afraid of going to the temple which is a quite silent place and my tinnitus will ring over most of the noises there. To the author of this thread I would suggest to stop looking for the source of that annoying noise, but rather place something in your bedroom that masks or distracts you from it. Like wind-up clock, small water fountain. If that helps with my ringing ears, it may help you as well.
