It is my opinion that you can have tinnitus ringing at a much higher frequency than the frequency at which your hearing rolls off. My hearing starts rolling off at 4kHz and is down 60db by 8kHz. But I'm sure my ringing is higher than 8kHz. No science, just my experience.
I can hear the guys talk just fine, I have trouble hearing my wife and children. The audiologist said, "hearing aids would be a waste for you."
That was several years ago, and I haven't noticed my hearing getting any worse.
Oh, I also have trouble hearing if there is other noise in the environment. I suspect this matches what other would say about their hearing.
