Anyone of you AES readers seen this paper?

http://www.aes.org/e-lib/browse.cfm?elib=12465

I was just wondering if this work indicates the presence of
nonlinear distortion can result in positive perception from
most listeners?

The work indicates that the presence of enough nonlinear distortion of
certain kinds is audible.

"Psychoacoustical data were measured, correlation and regression
analysis were applied to examine the relationship and predictive value
of this new metric to the subjective assessment of sound quality of
nonlinear distortion. Furthermore, conventional metrics such as total
harmonic distortion (THD) and intermodulation distortion (IMD) were
also compared. "

I'm interested in the subjective assessment of sound quality.

A bit and this was quite interesting.

http://www.gedlee.com/downloads/THD_.pdf


However this was a bit disappointing
0-imperceptable, 1-just perceptible, 2-perceptible but
not annoying, 3-annoying, 4 very annoying, 5-intolerable.


I don't think this scale addresses the subjective
perception of sound quality, apparently assuming that less
is better.


Not really.

The key is understanding what the scale is talking about.

The scale is trying to relate two things - nonlinear distortion, and
listener satisfaction.

A rating of 0-imperceptable would be assigned to subjectively perfect and
satisfying reproduction. IOW the reproduced sound matches the origional
sound and the reproduced sound is as satsifying as the origional sound. What
could be wrong with this?

A rating of 5-intolerable would be assigned to subjectively completely
mangled and entirely unsatisfying reproduction. IOW the reproduced sound no
way matches the origional sound and the reproduced sound is not the least
bit satisfying. What could be right about this?


http://www.gedlee.com/downloads/Comm...n%20howard.pdf


ends with,
"The bottom line here is that we know so little about how
humans perceive the sound quality
of an audio system, and in particular the loudspeaker,
that one should question almost everything
that we think we know about measuring it. From what we
have found most of what is being done
in this regard is naive. Things like distortion
measurements that don’t consider masking, or axial
frequency response that does not consider the reverberant
field or arrival time issues of group
delay. Maybe someday in the future we will be able to
quantify perceived sound quality and
move audio away from a marketing dominated situation to a
data driven one."


In fact we can quantify perceived quality, but only in the grossest possible
way. We can define numbers for a set of parameters that results in
reproduction that is indistingushable from the original.

It is possible to find individual components such as amplifiers and CD
players whose performance conforms to these parameters, and in practice the
parameters are good predictors of sound quality in a pass/fail sort of way.

When it comes to other components like transducers (which is Geddes area of
expertise and concern) we can't find any components that meet the current
pass/fail criteria.

Basically, Geddes wants to find a more sophisticated way to define and
gather data for performance parameters that allows us accept products with
lower performance, providing their performance conforms to the new
parameters. More specificially, instead of saying that anything whose
imperfections are less than say +/- 0.1 dB and 0.01% nonlinear distortion
provides subjectively ideal performance, we find ways to measure and analyze
performance so that equipment with far poorer performance that that with
traditional measures, still provides subjectively ideal performance.

This would seem to indicate that parametric objectivists
don't have a sound scientific basis upon which to rest claims
of superior performance.


Congratulations Scott. You've just invented a new phrase that google finds
zero instances of on the entire web - "parametric objectivist" I can guess
at what you mean by it, but rather than doing that, why don't you define it?

Wrong. The assumption is that less audible distortion is more pleasing and

It comes down to whether you want your audio system to be a reproducer or a

It will pass a straight wire bypass test.

It is simple. People who judge unit performance based
upon accepted parametric measures of performance even if
those measures may not be complete enough to assure subjective perceived
quality. '


Looks like a straw man.

Taken to the ultimate we get exactly what I said.


That's called an excluded middle argument, Scott.

And we also know that many listeners prefer a bit
of distortion.


What we know is that with suitable hype and deception such as the LP
preference weirdness, listeners can be coaxed into ignoring and even
preferring certain amounts and kinds of audible distortion, despite their
well-known deliterious effects on realism.

You seem to believe the Keith Howard has the last
word on the subject.

Mr. Howard's little piece of garbage is intellectually repugnant. More
excluded middle thinking.

Like I said once before...I've heard a small drum kit in my

Proves nothing. First off not all drums sound the same. Maybe you just
didn't like those drums. Secondly, acoustic instruments differ from a
well-designed audio system in that they have very limited or no facilities
for being adapted to a particular room.

So I think in all honesty, we're all doomed to EFX machines
for maximum enjoyment.

I was trying find Linkwitz characterization studies for

the tests on his site now..


1 % THD is 10-20 times the threshold of audibility for certain kinds of
amplifier distortion.

track.


Yes, and...?

I want to be deceived by my senses into thinking a really nice

Speak for your own flatulence, Scott. If you are outgassing a lot, let me
recommend Prilosec OTC. Works wonders for a number of aspects of
less-than-optimal digestion.

Don't show your obvious envy.


I'm not envious of Hiraga's poor command of the relevant facts and poor
logic. Being published in SP is like wearing the scarlet letter of audio.

It's just a hypothesis...and one that may be based
upon improving the shortcomings of recordings
to a more enjoyable rendition, even if it is not "real".


Its a poor hypothesis.

A rating of 5-intolerable would be assigned to
subjectively completely mangled and entirely
unsatisfying reproduction. IOW the reproduced sound no
way matches the origional sound and the reproduced

Let's see, that's Schopenhauer debating trade trick number two - extend your
opponent's argument beyond its natural range...

If the recording/mixing/mastering process loses something that
can never be retrieved, then purity in the last links seems silly to
me.


Yeah, why not try to make pure water by throwing random gobs of mud into it?

with distortion numbers below that which is considered
inaudible in amplifiers.
Examples, please.


I was trying find Linkwitz characterization studies for
alternative drivers where I (IIRC) he had selected
some less than 1% THD drivers. But I don't see
the tests on his site now..


1 % THD is 10-20 times the threshold of audibility for certain kinds of
amplifier distortion.


and for typical speaker distortions?


There aren't any reasonble speakers that have 1% THD 20-20 KHz at say 110
dB.

Basically, Geddes wants to find a more sophisticated way
to define and gather data for performance parameters
that allows us accept products with lower performance,
providing their performance conforms to the new
parameters. More specificially, instead of saying that
anything whose imperfections are less than say +/- 0.1
dB and 0.01% nonlinear distortion provides subjectively
ideal performance, we find ways to measure and analyze
performance so that equipment with far poorer
performance that that with traditional measures, still
provides subjectively ideal performance.


This would seem to indicate that parametric objectivists
don't have a sound scientific basis upon which to rest
claims of superior performance.


Congratulations Scott. You've just invented a new phrase
that google finds zero instances of on the entire web -
"parametric objectivist" I can guess at what you mean
by it, but rather than doing that, why don't you define
it?


It is simple. People who judge unit performance based
upon accepted parametric measures of performance even if
those measures may not be complete enough to assure subjective
perceived
quality. '


Looks like a straw man.
You're seeing things.


I'm seeing a lot of pseudoscience, bad logic, and misapprehensions in
your
post, Scott


Thats is what you always do.


Only you can stop that Scott - clean up your act and stop deifying vinyl.

Not necessarily, that's something else entirely.
