As a hearing specialist, this post intrigues me. I have been using stringent test protocols for more than 15 years during my hearing evaluations and have yet to have one patient/prospect report to me that my test increased tinnitus perception levels. Numerous audiology studies indicate that short bursts (test tones) even at 110 dB are not enough to damage the cochlear nerves. Certainly, this holds true for tympanometry, as the tones are administered at low levels. The formula for nerve damage (i.e. sensorineural loss) is loudness times duration. Sustained loudness above 80db for 1/2 hour is the same potential damage of 90dB for 15 minutes. (This is only an example.) Genetics also is suspected to play a role in the eventual effects, as well as the acoustical environments, susceptibility to hyperacusis, tinnitus, ear infections, pharmaceuticals, and other health issues that may impact said damage. Depending upon which school of thought one adheres to, tinnitus levels vary based on how one's brain preceptors perceive the affects of the damage. This is why Tinnitus Rehabilitative Therapy may actually work. If one can habituate to the therapy sounds then the focus may be shifted from the tinnitus affects to other lesser affected frequencies causing a shift in one's perception of the perceived sound. Masking the sound, if possible, by way of normalizing stimulation to the affected nerves by way of proper amplification will generally mitigate the effects of tinnitus in up to 95% of those affected with this malady. It may not rid one of the tinnitus, but to imply it will make it worse depends upon too may variables as to generalize this possibility. Also, if you are not familiar with the terms "hidden hearing loss" it would be advisable to peruse the available information for more understanding of the problem. Hope this sheds some light on this most relevant issue believed by some to be suffered by as many as 50 million Americans, some with normal hearing thresholds.
