Science as magic
Arthur C. Clarke was right on the money in his famous remark that sufficiently advanced technology can be indistinguishable in practice from magic. Ever take antibiotics for a lung infection? One starts to feel better in hours. (assuming it is not antibiotic resistant). It really is like a magic spell.
But this works the other way around,. too. Since science is complicated and lots people do not understand it very well--and no one understands all of it in detail--the possibility exists of passing magical thinking off as science.
There is no reason whatever as such to make a speaker in the shape of the human cochlea. It may be that this shape happens to work well by accident but accident is what it would be. This is strictly superstitous thinking--or someone's idea of a joke. But perhaps naive people could be persuaded that this has some basis in science simply because they do not feel confident enough of their grasp of science to be firm in their common sense(and correct( view that it does not.
This kind of stuff is all over the place and not just in audio. "Science" is rapidly turning into the new version of superstition. Instead of the shaman telling the people nonsense, we now have the self styled scientist providing nonsense on the basis of it being "science" . It is amazing to watch. And a little frightening.
