>>1) Symetrical tinnitus developing in your 50's 60's, is unlikely to be clinically significant. It represents hair cell degeneration in the Cochlea, usually, but not always accompanied with some hearing loss, mine is'nt.<<
This statement seems impossible.How could you hear a test frequency when your ringing ears are masking it.I went to one ENT group years back and saw the equipment used for the hearing test and could say it was of poor quality.They said they only need to test the few frequencies that were printed out on the paper they gave me.If your ringing isn't in this this limited test range,it may give the illusion you have no hearing loss.If they changed the standards to high quality tests and equipment,there may be a lot of more accurate results.Apparently,if more money was to be made in this type of medical research,with more profit returns for the pharmaceutical and other interests involved,there might be better help for the affected people.
