Ok, now I understand why I have been experiencing a ringing or tinnitus in my hears after listening to my iPod or Shuffle while working out. I tried to use my iPod to drown out the TV noise in the gym. However, when I do not wear my ear buds, I feel much more relaxed and can rest better. Maybe it is in my mind, but I have to admit that the problems of noise polution is driving my away from the gym. My ability to hear is very important as a classroom teacher. Sure it is cool to wear the iPod around but I have to amid that tinnitus is something I want to avoid.
