I am exercising on a machine and 2 machines down I hear music blasting from this women's Ipod. So I think should I say something or not. I go over to her and jesture for her to take the ear plug out of her ear. She glared at me but complied. I said your music doesn't bother me but I have tinnitus from noise exposure and you may want to google tinnitus/mp3 players to learn about it. Well she looked at me and said, "Sir, I only listen to it this loud when I exercise." Oh well, I won't do that again. Some people will learn the hard way. I only wish someone had come over to me and said something. I would have at least researched it and not have taken offense and been rude. But it all depends on the individual. I spoke to a young man who was a drummer and he was distressed over the ringing in his ears. He had never heard of tinnitus but was appreciative that I told him about it.
