Dear @mijostyn : I'm sorry to read that coming from you with out any evidence that can support your " idea " when here is the support ( linked. )/evidence of what the whole body can listen ( bones are only a media in our body and I think that you read but not really read the brain preambule information:
"" X. Significance of the results
Given the existence of musical-instrument energy above 20 kilohertz, it is natural to ask whether the energy matters to human perception or music recording. The common view is that energy above 20 kHz does not matter, but AES preprint 3207 by Oohashi et al. claims that reproduced sound above 26 kHz "induces activation of alpha-EEG (electroencephalogram) rhythms that persist in the absence of high frequency stimulation, and can affect perception of sound quality." [4] Oohashi and his colleagues recorded gamelan to a bandwidth of 60 kHz, and played back the recording to listeners through a speaker system with an extra tweeter for the range above 26 kHz. This tweeter was driven by its own amplifier, and the 26 kHz electronic crossover before the amplifier used steep filters. The experimenters found that the listeners' EEGs and their subjective ratings of the sound quality were affected by whether this "ultra-tweeter" was on or off """"
Please you or any one else come here with true evidence/facts that proves that our wole organism can't listen over 20khz and why can't.
With all respect your opinion about means " nothing " in favor or against that issue with out " support ". Mijo, bone is only and example and not even you can prove that changes in the air SPL can't be detected by bones.
