I did a little research, and it turns out this is indeed the case. The item that was most intriguing for me personally came out last month. German researchers Hidehiko Okamoto, Henning Stracke, Christo Pantev and Wolfgang Stoll reported that altering commercially available music improved the symptoms of tinnitus. That's good news for any of us who might have spent a little too much time wearing headphones or hanging out in loud clubs or sitting next to computers with loud fans. They found that test subjects who listened to music "notched" to dial out frequencies in the range of their tinnitus often had improvement after a year, compared to a control group. They believe tinnitus may be a refactoring of the auditory cortex due in part to lateral inhibition.
