Had my morning appointment at the ENT surgery clinic, this morning (
www.acquaklinik.de). As predicted, the hearing test they use is 0-8 kHz. I did the test using a pulsating frequency (which is easier to hear for people with tinnitus). As the test was only 0-8 kHz, I asked the clinic to set up an appointment for me at another clinic if they could find one where the frequency is > 8 kHz. They did find one and I went there at 14 o'clock, today. This hearing test was a non-standard, non-pulsating frequency hearing test. The tests were done 4 hours apart. I had no noise exposure between the two tests. The last test was repeated for the 12,5 kHz frequency, both left and right ear. Comparison tests are the ones done last summer at dr. Wilden's practice in Regensburg (which I believe is now relocated to Spain).
Conclusion
My overall conclusion is that there in the audiotory speech frequency range (0-8kHz) is an overall improvement of 0-20 db vs. my very first audiogram done 10/JUN/2013; the improvement is beyond "statistical uncertainty" for 6 and 8 kHz. For 12,5 kHz, the result is status quo. Today's result compared with my audiogram done after 2 months laser therapy, last summer, shows a decline. My hearing ability from today's test indicates that my hearing - in the audiotory speech frequency range - is approximately equal to that of a normal hearing 20 year old (and I am 36).
I believe my current tinnitus frequency is affecting my ability to hear the higher frequencies (> 8 kHz) when using a non-pulsating hearing test.
Analysis
The most component influencing today's result is probably the "like-for-like" factor. By "like-for-like", I mean that tests should be carried out using identical criteria. The two tests done today - and with only 4 hours apart - show just how much variation there can be. This variation is due to testing standard (eg. pulsating, non-pulsating), testing environment (eg. properly noise insulated hearing cabin - or not in some cases), testing equipment (slight lack of calibration, responsiveness of equipment), the audiologist (eg. rapid/slow increase in volume for testing frequencies), and of course the patient him-/or her-self.
It has many times been indicated that Dr. Wilden's treatment is a scam - and that his hearing tests are somehow manipulated. I am not here to defend Dr. Wilden (he can do that himself), but I will say that based on today's experience, I can offer some explanation as to why there might be differences between his tests and other hearing tests. First of all, where would someone buy hearing test equipment designed with the sole purpose of cheating patients? Secondly, the fact that his tests show a better result than that of other hearing test providers is actually an indication that he has taken more care to create a reliable test environment (if you were to ask me). What do I mean by that? Well, today's hearing test at the acquaklinik was actually not that impressive. The room was not properly noise insulated (only slight padding on a normal door), there were wooden floors just outside where patients would walk right by, and the audiologist was located inside the room together with the patient - fiddling about with the equipment throughout the test. And that shows on a hearing test - as you can see...
But then in most cases, hearing tests are just for indicative - and not "scientific" - purposes. But, in my case I will probably need to find a clinic that offers:
1) 0-16 kHz test
2) a properly insulated testing cabin
3) pulsating frequencies
4) separation of patient/audiologist
5) slow increase in volume for all frequencies.
I would like to mention - in the acquaklinik's defence - that their main competence is not hearing assessment/diagnostic, but surgery. The staff there is highly competent, otherwise. My doctor today was a young female non-surgeon doctor - honest, direct, and competent. And able to answer all my questions. Just how I like it...
Tomorrow, I will meet the ENT professor in charge of surgery.
I did not have scanner handy today, so I took photographs of the hearing tests indstead. Sorry about that...
