@R. David Case, I read Dr. Dinshen paper when you posted the manuscript in Tinnitus Talk, and I already told you that the paper has very low scientific quality, and speaks very poorly about Dr. Dinshen (who is somewhere lost in the prestigious Mauritius island). It should not pass any peer review systems unless goes to one of those random only Internet journals.
Some remarks about the paper:
1) The paper only analyzes your Tinnitus Mix and Koss headphones. A minimally serious study should include other noise types (impulse, white,…) and a group of headphones from different makers to compare the output. This will help to understand if there is anything particular about your file and Koss headphones.In the way the study is presented there is only one file and one kind of headphones, and the consequence is that there is only one possible result. This is just another example of your completely biased view of the world.
2) The paper shows the Tinnitus Mix FFT (Fourier Transform) having a peak frequency at 8 kHz, and low power at higher frequencies. This is against your propaganda that Tinnitus Mix is special because of very high frequency content. Doing the analysis of the Tinnitus Mix with any FFT iPhone reveals similar conclusions.
3) The spectral response of the Koss headphones is only plotted to 8 kHz and has very few points. This plot goes against any conclusion you can make about very high frequency convolutions.
4) Spectral convolutions are prone to error for very high frequency calculations and one should very cautious about their interpretations. It should be checked that with different libraries (Matlab, python,...) the results are consistent. The very poor representation of the Koss headphones does not bode well for reliable conclusions, and again, why not to try the spectral response of many other headphones?
5) If there is any 2.8 MHz radiation, it should be measured, and avoid to present very questionable calculations.
6) Biological effects of 2.8 MHz are not clear, and this enter the same realm as people who believe in LLLT (Low Level Laser Therapy) and the experimental evidence is basically non-existent.
Your logical thinking requires ever increasing acts of faith: Tinnitus Mix is magic, Koss headphones are magic, two magic elements together produce even more magic (2.8 MHz), and it turns out that this magically will regenerate your cochlea. This is just obvious magical thinking and pseudoscience, and it is what annoys me the most about the Tinnitus Mix.
Also you mention that I do not have technical knowledge or that I am not smart enough. I do not have a PhD in Neuroscience, but I do have a PhD in Physical-Chemistry, 60 papers in International journals, 15 patents and I lead a group of PhDs in a high tech company in Silicon Valley. I have reviewed many scientific papers and I have enough experience to distinguish whether the scientific method is followed properly or not.
