Now hold on there.

DBT means "double blind test", no more, no less.

Some people equate ABX testing with DBT's.

A lot of people falsely equate ABX testing with sequential ABX testing.

Some people insist that, despite the tons of evidence regarding the length of primary auditory memory (200 milliseconds give or take), "fast switching hides results" which of course is as far from what the serious types have figured out as you can get, but so it goes.

And then we have the people who talk about how it stresses them.

A real DBT, done right, will be double blind, it will allow seamless switching, under the control of the subject, and will allow the subject as little or much time as they want.

And it doesn't have to be ABX.It can be ABC/HR, it can be AB-signal detection, there are more ways to skin a cat than most of them here imagine.

But "double blind test" means, simply, that neither the test administrator that's present during the test (if any) and the subject know what the probe stimulii is. They may, and should, know what all reference stimulii are at all times.

Now, ABC/hr, ABX, and AB-signal detection tests (for probes that apply) have all been shown to work with noise, tones, music, single instruments playing single notes, complex soundfields with music and speedh (and that as far back as the 1920's), and pretty much any sort of acoustic stimulus.

It's only the high end that denies the evidence of the matter.

Btw, I like DeLille, perhaps it's a question of taste. What sort of cab/zin/bordeaux-like red do you like?
