At this point a real audio heavy weight called Bob Marcus
took the stage and sounded off thus: ""No, that is not what we said at
all. Scientific investigation has *proven*, beyond a shadow of a
doubt, that speakers are almost always distinguishable by sound alone"
And what is the truth?
In September 2003 Sean E. Olive , Fellow of Audio Eng.
Socy., a genuine audio researcher not a RAHE loudmouth,. published a
paper in the Journal of Audio Eng. Society on p. 806 entitled
"Differences in performance and preference of trained versus untrained
listeners in loudspeaker tests"
He found only TWO previous loudspeaker
listening studies and accepted ONE ONLY as valid research. So much
for Marcus's "beyond a shadow of a doubt"
Questioning the validity of previous studies sheds no light either way on
the claim that "....speakers are almost always distinguishable by sound
alone.".
The validity of previous studies is irrelevant to whether or not
"....speakers are almost always distinguishable by sound alone.".
These are quite clearly different topics. One has to question why someone
would want to confuse them.
And the conclusions? "Significant
differences in performance. were found among the.different categories
of listeners." He was interested only in comparing groups (Piquantly
audio reviewers were the worst performers!- by this kind of test,
anyway.). His best performers were his trained technicians. BUT his
web site posting of previous group of tests showed enormous
differences in individual performance WITHIN his trained group (from
30 to 70% correct answers)
Studying the performance of different categories of listeners sheds no
light either way on the claim that "....speakers are almost always
distinguishable by sound alone.".
The performance of different categories of listeners is irrelevant to
whether or not "....speakers are almost always distinguishable by sound
alone.".
These are quite clearly different topics. Again, one has to question why
someone would want to confuse them.
Am I alone not being able to follow the logic of this argument?
