Does Daniel Levitin, author of "This is your brain on music", count as someone with "a decent understanding of music and acoustics" ? He thinks that Helmholtz explained harmony (he told me personally). However, as the essay points out, (1) The American Acoustical Society collection has an experiment stretching frequencies from 2.0 to 2.1 that they conclude shows that Helmholtz was wrong, and (2) if Helmholtz was right, there would be not harmony at all, as the essay points out. So even someone like Levitin is wrong.
