I had/have tiniitus from a year in my early 20’s as a rep, high speed motorway journeys with the window open and radio blasting wayfarers on…
Anyhooooo it bugged me really badly for about a year until I found out about this american doc who did double blind research with tinnitus sufferers and non tinnitus sufferers. He put them in soundproof rooms and played random noises at random levels, and found no correlation between sufferers and hearing npise, in fact lots of non sufferers reported noises when there were non and vice versa. So he came up wtih “retraining therapy” where he showed people this effect and convinced them that all people have ringing/noises it just some have been made aware of them due to damage or infection etc.
The upshot being that I essentially trained myself to filter it out and I can actually turn it on or off at will.
How? Embrace the noise, trey and love it, look for it, expect it, be happpy when you hear it, one morning you will wake up and it wont be there.
OK. If this all sounds like a load of crap, and maybe it is, but it worked for me, comprehensively. I’m a scientist, and really only respond to evidence, I read this guys research and the evidence was there, the rest was up to my own interpretation.
