I once read in an acoustics book that even ordinary people can perceive frequencies up to 200,000 cycles in the sense that they can tell that sounds are different, even if they only differ by harmonics in that very high frequency range. Unfortunately, that was about 35 years ago, and I can no longer remember the name of the book or it's author, for certain. I thought the author was an englishman named white, but people on another music forum were very skeptical, and couldn't locate such a book. Does anyone here know the real answer?
