2.7 Blind versus Sighted Listening Tests
It is generally accepted among scientists that psychometric
experiments
must
be
performed double blind. For audio tests, this means the identities of
the
components
under test cannot be made known to the listener, and the experimenter
cannot
not directly
control or administer the actual test.
In 1996 Toole and Olive in [2] conducted some blind versus sighted
loudspeaker tests
that showed both experienced and inexperienced listeners' judgments
were
significantly
influenced by factors such as price, brand name, size and cosmetics.
In
fact, the effect of
these biases in the sighted tests were larger than any other
significant
factors found in the
blind tests, including loudspeaker, position and program
interactions.
These
experiments
clearly show that an accurate and unbiased measurement of sound
quality
requires that
the tests be done blind.
Good, old NYOB discovers America. Yes, Sean Olive sensibly used double
blind
BUT NOT ABX.
Who's against double blind and motherhood when apropriate?
Copy from my posting to the High Priest Arny:
"Repeat : no quarrel with double blind comparison. It removes one
source of
bias. But to imagine that just because you listened double blind
you're
entitled to lay down a rule for me is nonsense. You're you with your
preferences, experience etc and I am I. There are many people whose
opinion
sighted I'd prefer to many others double blinded"
Like for instance....

Exactly right, Ludovic.
Stinky Mikey the mckelviphibian can't help stinking up the place.
Compared to you, I'm a breath of fresh air.
Mikey, you can't breathe. You can only expel air from your bladder.
Keep your skin moist. It's important for adequate oxygen exchange.
