In Reply to: Well, if you do a DBT right, it is as good as anyone knows how to do... posted by real_jj on June 22, 2006 at 13:50:38:
I think it would make sense to consider rejecting the negative result of a blinded test if it conflicted with follow-up sighted listening. I would be inclined to reject the results rather than think I was persisting to hear something despite proof it didn't exist.
Follow Ups:
What about those who freeze up during tests? Afterall a DBT is a test. Whether you are requiring someone prove what they've learned through exams or you are requiring someone to prove what they hear. You are placing a pressure on the person to perform.I recently obtained my 2-20 General Lines Insurance Agent license. I needed to sit outside the office where I would be taking the test for almost 45 mins before I could go in. I always panic when I have to take tests, period. I have to believe that plays a part in DBT's as well...
A while back, I tried to find a difference in two very smilar recordings by the same artist. After concentrating on listening to one after another at length, I found no difference, and gave up out of fatigue and boredom. Later in casual listening, I identified one difference. The music was in the background at the time, and I was thinking about something else, when the difference struck me.

Assuming the test is well-constructed, of course.What it would indicate would seem rather clearly to be that the sighted listening was causing some other issue to bias the test.
This is not a bad thing, to use an extreme example, if one amplifier is 6' tall and lined in flashing violet neon lights, and the other isn't. :)

Will you elaborate?As for your huge lighted amplifier, being hard to ignore, it could influence a listener(favorably or not). It's interesting that electronics from Japan were flashy while those from Britian were the opposite.

I would not conclude that the DBT was flawed if you were consistant in the sighted test. I would conclude that more than what you can hear creates your preference. (note, there is nothing wrong with that)How things look, etc, will influence anyone, no matter how hard they try not to be influenced. (A blind person of course won't be influenced by the look, but the name, etc ...)
My point about the large ugly amplifier is that I suspect I would toss it off the side of the deck (btw, that's 12' AGL at my house) even if it took both teenagers to help me do it.
In other words, appearance does matter. I don't need to stare at a really ugly amplifier...

That's the other conclusion, and I can't say it's wrong. But if faced with two possibilities, I lean toward the one I like. In this case there is no need for me to choose between the two, since a choice would not affect me either positively or negatively.

You pick what you like, how you like to pick it.
