If you read the Oohashi paper you will see the trouble they have gone to to source ultrasonic music from gamelans special playback equipment special tweeters etc  everything checked from source to speaker system Meyer Moran does not even seek to be a test of ultrasonics It does not pretend to be a test of ultrasonics It does not claim to be a test of ultrasonics If you wish to assert that Meyer Moran is a test of ultrasonics you will have to formally prove that EACH AND EVERY ONE of the elements of the chain passes the ultrasonic test So lets check it out   Source material    This is discusssed at   httpwwwsacdnetshowthreadphppage It turns out that the vast majority of source discs used by Meyer Moran were recorded in the s  s or s  they are CD quality masters and therefore do not have ultrasonic content   Summary SOURCE MATERIAL   FAILS ultrasonic test   The playback equipment used by Meyer Moran has to be able to reproduce ultrasonics  The source equipment used by Meyer Moran is listed at httpwwwbostonaudiosocietyorgexplanationhtm The principal equipment consisted of an Adcom GTP preamp and Snell CV speakers  You can find the specs for the Adcom GTP preamp here  httpwwwusersinterportnetadadcomgtphtml  The specs are listed as Hz to kHz  FAILS ultrasonic test  The specs for the Snell CV speakers are given here  httpwwwstereophilecomfloorloudspeakerssnellindexhtml  They show massive dropoff above  kHz FAIL  Summary  The playback equipment used by Meyer Moran cannot reproduce ultrasonics properly  GRAND SUMMARY  Meyer Moran is not a test of ultrasonics Meyer Moran do not claim it is a test of ultrasonics The only person claiming that it is a test of ultrasonics is you it is  your own original research which is a violation of the Wiki original research provisions Worse your claim is  completely flawed and erroneous at EVERY LEVEL of the chain from source material through to speakers  Ill leave this up for a day or so for some discussion If you cannot prove your original claims then  out it goes  PS Your Lehrman  reference is just a quote of Meyer Moran  it also has absolutely nothing to do with hypersonic or ultrasonics You might want to take this to the CD advocacy page  but it has nothing to do with the ultrasonic effect Out it goes
