Hello! If you are frustrated by your health care providers telling you "everything looks fine" after looking at your audiogram or making you listen to a tuning fork, then sending you home without a more in-depth explanation, you might want to give their diagnosis a second thought. Perhaps they left out some tests that are showing to be useful in the proper diagnosis of tinnitus.
According to research both older and newer, testing frequencies beyond 10kHz is necessary for obtaining useful information for tinnitus patients who report higher frequency pitches. Drawing conclusions based on audiograms that only show typical speech frequencies up to 8kHz is inadequate and leads to higher rates of "idiopathic" diagnoses, and is leaving out the opportunity to collect important data for research on tinnitus and hearing loss.
You may want to print out a copy or email this to your audiologist, ENT, or even general practitioner to update their knowledge (which may require updating):

The above article contains relevant research justifying the need for ENT and Audiology clinics to utilize audiometry that ranges between 8kHz all the way up to 20kHz, and contains strategies and suggestions for dealing with concerns of repeatability and testing duration.

Although the conclusion of this particular research project said that the exact (or close approximation) frequency of tinnitus wasn't significantly correlated with the edge of the high-frequency loss, it was reported that patients had tinnitus frequencies that were higher than the edge of the hearing loss on the audiograms. This shows that we can at least get some useful information through extended high-frequency audiometry. Newer research is expanding upon these findings mentioned below.

The above article suggests that "speech-in-noise" tests are more useful than typical pure-tone audiometry (only going up to 8kHz) for diagnosing problems of hearing in noisier, social environments. "Threshold assessment at high frequencies (from 10k - 20 kHz) should be considered for inclusion in test batteries when patients report difficulties understanding speech-in-noise despite audiometrically normal thresholds up to 8 kHz. Although there are no clear causal relationships between high frequency hearing and speech-in-noise test performance, high-frequency hearing loss in relatively more noise-exposed participants has been reported by multiple teams (citations 33,36,37) and may be one of the first changes among long-time users of personal audio systems.(75)... Empirical data are needed to assess this specific suggestion, and determine the strength of any potential relationships between high-frequency hearing and speech-in-noise performance. Regardless, documentation of deficits to the high frequency regions of the cochlea will provide a tool for counseling patients on the importance of protecting their ears from loud sound to reduce the risk of further damage."
