The Dishonesty of Sighted Listening Tests
An ongoing controversy
within the high-end
audio community is the
efficacy of blind versus
sighted audio product
listening tests. In a blind
listening test, the
listener has no specific
knowledge of what
products are being
tested, thereby
removing the
psychological influence
that the product’s
brand, design, price and
reputation have on the
listeners’ impression of
its sound quality. While
double-blind protocols
are standard practice in
all fields of science -
including consumer
testing of food and wine
- the audio industry remains stuck in the dark ages in this
regard. The vast majority of audio equipment manufacturers
and reviewers continue to rely on sighted listening to make
important decisions about the products’ sound quality.
An important question is whether sighted audio product
evaluations produce honest and reliable judgments of how the
product truly sounds.
A Blind Versus Sighted Loudspeaker Experiment
This question was tested in 1994, shortly after I joined Harman
International as Manager of Subjective Evaluation [1]. My
mission was to introduce formalized, double-blind product
testing at Harman. To my surprise, this mandate met rather
strong opposition from some of the more entrenched
marketing, sales and engineering staff who felt that, as trained
audio professionals, they were immune from the influence of
sighted biases. Unfortunately, at that time there were no
published scientific studies in the audio literature to either
support or refute their claims, so a listening experiment was
designed to directly test this hypothesis. The details of this test
are described in references 1 and 2. |
