If you know what The Hum is and you suffer/ed from it, then you won't want to listen to this video. But if you want to find out about it, this is a very good report and amazing research into this horrible droning, low pitch sound that's not the same as tinnitus. I used to suffer from the hum and got rid of it with relaxation technique/distraction. Until I think about it, and then it's back (boo).
