Not making any assumptions. I hear what I hear. You couldn't convince me the dog I'm looking at is a cat just because you're a veterinarian. Cheers.
Respectfully, you are indeed making assumptions. You are assuming that you have heard true content in these frequency ranges, and that you know what it sounds like. You are assuming that your experience is hearing sound pressure rather than feeling air pressure. You are assuming that your reproduction devices are accurate. You are assuming your knowledge is complete.
To use your metaphor, if you had never truly identified which was a dog and which was a cat, and believed a cat was a dog because that's what you'd always been told or assumed, you might reject the truth told to you by a vet in favor of a false perception. You might not believe a vet just telling you, but if a vet is pointing you toward outside references generally accepted by the rest of society and asking you to test your knowledge and perceptions according to those references, you would find through that process that what you're indeed seeing is a cat, not a dog.
Have you ever had your assertions tested in a double-blind scenario, as was mentioned earlier? Using the testing method you described, where you are in control of the test parameters, you are subject to confirmation bias. It would also be interesting to see an analysis of the actual frequency content you are hearing. There is a difference between natural harmonics, which ALL electromechanical reproductions have, and layering in generated harmonics. The effect would be completely different.
Further, if you are listening in earbuds or headphones, you are experiencing a different pressurization method than real world sound. With both ears receiving an identical signal but being pressurized from different directions, you are certainly more apt to perceive that signal from the sheer air pressure. Experiencing that effect is not the same as hearing the frequency. If you were to produce a similar SPL at your ear from a distant point source somehow devoid of all natural harmonics and reflections, your ears would experience the sound pressure, but not the air pressure. You would perceive that very differently, and perhaps not at all, depending on the circumstances.
To not be willing to test your knowledge, thereby admitting the
possibility that you might be wrong, is basically the same as egotism. Basically what you are saying is that you know more or better than everyone else. That type of attitude won't get you very far in life, unfortunately.
