Given the brevity of aural memeory, (borrowing the phrase from Sean) I'll bet dollars to donuts, that few of you have conducted a valid hardware DBT audio test. 30+ yrs ago, I did nothing but set up the switching mechanisms for (admittedly non audio) tests at Hopkins Medical School and the Maryland Psychiatric Research Center. Whatever anecdotal results have been discussed here wouldn't pass peer journal review criteria of those days, let alone whatever minimal criteria are acceptable today. Its straightforward to set up valid SBT or ABx tests, iff you have circuit level access, and you're dealing with a situation where (generally) nothing is turned off, levels matched and interruptions of sound <5 seconds. This is why the Good Lord, in Her infinite wisdom, has given us 4pdt switches, if you're dealing with something as straightforward as power conditioning. And its not that incrementally difficult to extend those tests to DBT with a computer and sufficient quality relays. But other areas.... good luck. Leastwise, this is what my students, 1 month away from recieving their BSEEs are finding out in their senior lab course. Its actually more comical to watch them breadboard and solder a simple circuit. > I just hope we don't get to the point of censorship, like banning any > mention of DBT (audiocircle) or not allowing any report of an > improvement without having first done a careful DBT (hydrogenaudio). > That really does stifle discussion, to the point that the board becomes > pretty boring. I've banned discussions about DBT in the Lab Circle at AudioCirle, not discussion of actual DBT tests. I'm a strong believer in valid testing. Its appears that folks find it far prefferable to invoke the shibboleth of DBT rather than actually perform a valid one. Personally, I find such discussions 'about' a boring, repetitive, fruitless exercise in Onnanism. But if talking about it, rather than actually doing a valid experiment, floats your boat, enjoy. -- occam ------------------------------------------------------------------------ occam's Profile: http://forums.slimdevices.com/member.php?userid=949 View this thread: http://forums.slimdevices.com/showthread.php?t=33547 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
