I had ringing in ears and even went to a hearing specialists. Tested and found hearing to be O.K. The doctor said he could find no reason for the ringing. Then I read about using acidophilus capsules or eating the yogart with live acidophilus bacteria----that it could stop the ringing in one's ears. Worked wonders for me. I took the capsules for about 7 days. I got the capsules at Whole Foods.
