>...training will increase the ability of a person to detect differences in a DBT.>
That proves it is a test of the listener's critical listening/test taking skills and invalidates it a scientific test of audio component differences.
In real scientific DBTs, does training the subject change the result of new drug clinical trials?
Laughable.

Well, well, now, I see the source of the confusion. Whoever said that an audio DBT was a test of audio component differences?

That would be you fewer than thirty minutes after asking that question!
A DBT may determine whether you actually can detect a difference in the sound of your system due to the change in the equipment.
Reading comprehension is not your strongest point. Let's look again at what I wrote.
"A DBT may determine whether you actually can detect a difference in the sound of your system due to the change in the equipment."
Where does it say the test is of the differences in equipment? It doesn't. We already know there is a difference in the equipment, and one need not even turn it on to know that. With reasonably accurate measuring equipment, one could doubt measure the performance of each piece and compare the differences.
As Tony Lauck has pointed out, a DBT provides data, and people determine whether the person doing the DBT can detect a difference from the sound alone. Saying that a DBT does it is a linguistic short cut.
The issue is whether the person doing the DBT can detect the difference from the sound alone.

Read again the second and third sentences. Aloud, if necessary.
In particular, pay attention to words found in both sentences!
'Differences' and 'differences one can detect from the sound alone' are not the same thing. As I said, reading comprehension is not your strong point. Neither is good will, I would guess.
