The problem with double-blind tests can be illustrated by the triangle below:

Because it's neither your ears nor your eyes, but your brain that does the fooling. If there's no easily-detected distortion, but rather "lack of information", your ears will soon fill that in and you will seemingly switch back-and-forth between similar-sounding audio. Meridian did a test of double-blind tests and concluded that they couldn't use it for internal tests. And since internal tests aren't to prove anything for anyone it's perfectly alright for them to use other methods. But for a reviewer, while flawed, double-blind tests may still be the way to go. But he/she should take them for what they're worth. -- tommypeters SB3-->Meridian G68-->NuForce Ref8.200W-->Bc Acoustique ACT A3 ------------------------------------------------------------------------ tommypeters's Profile: http://forums.slimdevices.com/member.php?userid=6528 View this thread: http://forums.slimdevices.com/showthread.php?t=67679 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
