Which of my experiments are you referring to? And what vast majority of the "'research'"? (Nice polemical use of ' ' marks by the way.) Last time I checked, the audio memory research was precisely about distinguishing differences. The way it works is, they play two sounds and see if the subject can differentiate them. Then they make the difference smaller and repeat. Eventually the subject can't hear a difference; that's the threshold. Then they change something (like how far apart in time the two tones are played) and repeat. That gives you threshold as a function of whatever you changed. The results are that if you have to wait more than a few seconds you are much less sensitive to the difference.

My point is that the research shows that people are *better* at noticing differences when the time interval is short. So for what you're saying to be valid, that research must be at best misleading. > > That is why we are saying that short-term A/B testing doesn't offer > much > useful information, and neither does long-term A/B testing (audio > memory > is too short). I guess we must mean different things by long-term A/B testing. Last time I checked it was difficult to determine if you liked A or B better without listening to both A and B (over whatever time periods you choose), thereby performing the dreaded A/B comparison. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=37553 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
