From: Ralph H.Oscarson, 1551 S. Welch Cir., Lakewood, Co. 80228, (303) 986-3270. Tinnitus-the sound only you hear. Mine is 24/7 and going on 43 years. Mine is very loud much like listening to a train nearby and the volume and tone can vary at any given moment. Nothing can be done but you should try different things; change diet, no loud noises, etc. I wish you luck.
