Very interesting, thanks for sharing this. That really struck me because for me personally, I prefer when my tinnitus clearly sounds like it's coming from my ear versus bouncing around my head. When it originates more from my ear, I can more easily pretend it's just an outside sound.
Yeah, it seems easier to habituate to if it's in your ear. It's probably easier when it's not in the dog whistle range too...
Does yours actually move back and forth from your head to your ear?
