Except they didn't say the experiment 'failed'. They simply noted, in quite correct fashion, that their results do not support audibility of the 'hypersonic effect'; and they cannot rule out that someone, somewhere, might be able to hear these supposed effects, unders some as-yet-untested condition, and that a larger test sample would give yet more power to the test. Rarely can any experiment cover the entirety of 'sample space' for the question being studied. That's why statistics exist, to allow us to make inferences when we haven't tested the entire population. Scientific facts, at base , are statements of probability. And Themis, eliminating gear-induced modulation distortion of audible frequencies by ultrasonic frequencies is a GOOD thing for such a test. Because if the 'effect' is just intermodulation distortion, then people aren't really perceiving 'hypersonic' sound itself. No need to invoke a conspiracy by the AES. -- krabapple ------------------------------------------------------------------------ krabapple's Profile: http://forums.slimdevices.com/member.php?userid=22334 View this thread: http://forums.slimdevices.com/showthread.php?t=54077 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
