I have a "symphony of disruption" if I were to start a symphonic metal band.  When I plug my ears, I have several constant tones.  Those have changed some.  Some new ones have either started or old ones have changed pitch or tone.  When I don't have my ears plugs its just crickets and buzzing and I cannot really hear any tones.  I don't think it has necessary gotten worse just the sounds have evolved some.  Not sure if its for the better or not.  I feel habituated so they may change, be reactive, loud or soft- at this point I don't really care.  I get annoyed at times but generally don't care.  Tinnitus in itself is not going to kill me.  It's not like I have stage 4 terminal cancer.  Perspective helps you cope with T.
