I have constant ringing in both ears from eight years as a Navy pilot. The Navy checks hearing in flight crews during the annual flight physical. The high pitched whine of the turbine engines powering the aircraft has effects on hearing and eventually leads to tinnitus. I wore hearing protection all time on the flight line and while flying but it took it's toll. Some days are worse than others, but it is there all of the time. It doesn't seem to effect my ability to critically listen to and enjoy music. I have been asked by friends to listen to their systems for evaluations and I have confirmed thier determinations or detected other things. I am curious. Several of you indicated that caffiene has an affect. Does a reduction in caffiene intake help or as in my case the damage has been done?
