Can a person hear a tinnitus (sine wave tone) at a higher frequency than what he can hear in real life?

E.g., a hearing test determines he can only hear at 11,000 Hz, but the tinnitus he hears is at 13,000.

Some people swear that their tinnitus is at a higher frequency than what they can actually hear externally. A popular way to check this out is via YouTube, “matching” one’s tinnitus tone.

Of course we don’t know how accurate the YouTube sine wave tones are. One video may play a tone that’s allegedly at 11,000 Hz and audible to the listener, whereas another 11,000 Hz upload may be undetectable at even the highest computer volume.

Since the sound of tinnitus is created internally inside the patient’s ear, is it possible at all that this can be a higher frequency than his actual hearing?

“The human range for hearing is roughly 20 Hz to 20,000 Hertz, but a typical audiologic evaluation tests 250 Hz to 8,000 Hz,” says Rachel Raphael, M.A., CCC-A, an audiologist with Mercy Medical Center in Baltimore.

“Audiometer limitations (usually to 12kHz, but can go higher on some high frequency specialized test equipment) may keep us from matching the true pitch of the tinnitus.”

How can typical audiologic evals detect hearing loss if the limit is 8,000 Hz?
