Thankyou for all your replies.
I gained some useful information on this topic of Tinnitus - I am comforted that I will actually be able to fly an aircraft despite this annoyance.
However, I regret that my question caused such an in depth discussion - It was not intended to do so - I only wanted guidance.
But many thanks to those of you that assisted- I forget who said that if you have such a thing as Tinnitus then you will try almost Anything to get rid of it, but that is a true statement.
regards to all
