LOL that is a GREAT question! I used to have a running joke with my previous audi of 15 yrs every time I went in for a hearing test. I’d say, “You know my tinnitus will make me FAIL the test, so just give me a ‘handicap’ booster on the score, okay?” To which he’d say, “Yeah. Now shaddup, git in that booth, and take the test!”
And of course my audiogram here proves, I’d always fail.
In my own humble opinion, tinnitus makes a difference! My ears ring at a constant pitch & volume below which I doubt I could hear the tone - warbled or not. Maybe warbling helps, but if tinnitus is making it hard to hear a tone, then I’m guessing that’s the benchmark you have to work with, right? Cuz the tinnitus isn’t goin away. And my own ringing ears bong more on rainy days, or if I take meds or many other situations.
So I’d just relax, lean in to it, take the test, and let the results speak for themselves - ringing ears or not. It’s probably the most accurate ballpark you’ll be in for fitting.
