It shouldn't be hard to find. Especially when it's so easy to posit an experiment to do such testing with DACs that can reproduce signals up to 192kHz. Simply generate, additively, some interesting spectra with and without frequency components above a person's established audibility threshold, and see if they can be ABX'd. (You'll want to ensure that your DAC isn't curtailing your frequency response prematurely, of course; you'll also want to ensure that your speakers can properly reproduce those frequencies, too, rather than only converting them into heat - which will certainly affect the tonal nature of the speaker's reproduction of audible frequencies... so decent crossover filtering for your woofers is probably advised too.) If a phenomenon can't be ABX'd reliably under advantageous conditions, it has no objective existence - and anyone trying to claim otherwise is peddling fairy stories. > What if you you realize that you feel better with that frequency on? If you haven't confirmed it objectively, you haven't "realised" anything - you've merely given yourself a shiny new superstition. > If its only you out of 100 people, its voodoo.

And the prize for "most egregious misunderstanding of the scientific process" goes to... _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
