I believe there were some posts in here about tinnitus (@jinsai @

There are actually some newish methods that you can use to DIY treat it. "Notching" is what I recently encountered. You just have to identify the exact frequency (or frequencies) of your tinnitus and then run audio of your choosing through an app that blocks out that frequency (with a 1 octave spread). There are some websites that do it (like
http://www.audionotch.com/app/tune/ ) but there are several smartphone apps (Tinnitus Pro on iPhone) that do the same thing and will dynamically notch your music library.
Not entirely sure how effective it is or how long it takes, but it seems promising.
