Had it for a good bit of my adult life with increasing intensity the older I got. Some days are a little better than others but never has completely stopped. Can't remember what it's like to not hear the ringing.

Ear plugs made no difference whatsoever as the ringing is deep inside my ears. I usually manage to ignore it most of the time but it helps a lot to have some kind of external noise like a radio or TV turned on with the volume turned up enough to distract from the ringing. It can be extremely annoying in total silence.

All I've ever read is there is no cure for it as the damage is permanent and not repairable.

As always, YMMV.
