Tinnitus is subjective, and I'm not sure I understand the article's explanation for measuring this. How do you know if a rat hears a ringing in his ears? How do you ask the rat if the ringing does (or doesn't) stop? How do you know if the ringing bothers the rat? How do you know this, Sam I am?
But, then again, I'm not a researcher. Not in a lab, or with a hat, or on a cab, or with a rat.
