In Reply to: Some questions on double blind testing. posted by Phil Tower on November 12, 2002 at 03:10:40:
Well...The tests that define the basic sensitivity of the ear are DBT's.
They show sensitivity that correlates very well with the minimum sensitivity possible given the physical processes (in specific the noise level of air at the eardrum (NOT at a microphone, it matters)).
Various forms of DBT testing and cognates (there are methods that are effectively blind tests that are not DBT's) have been used pretty much from the inception of audiological and psychoacoutic research, and have provided self-consistant tools for that time.
So...
I think that a PROPERLY EXECUTED DBT can not be argued to miss very much at all. I can't say "nothing", because NOTHING is absolute in science, but I can "not very much" meaning that missing things a few .1ths of a db above audible threshold are very likely to be detected.
There are, of course, poorly executed DBT's as well.
