I have had ringing in both ears since the mid 1990's. I used to work in factories where hearing protection was optional and not encouraged. My ringing is constant at around 7000 hz. Occasionally I may get some clicking. I have never had any treatments for the ringing at all. I am in my mid 50's now and the ringing seems to be getting louder or my tolerance for it is getting shorter. I am researching remedies or masking to get some relief.
