Did Amir Change Your Mind About Anything?

@amir_asr Gremlin or Aztec? The world wants to know! You should post your answer on your site though.

@amir_asr  - little reminder, amir : )

Thank you for your quick response, amir. I hope you won’t mind if I can clarify an issue (I realise how many queries you are attempting to answer at the same time, so I fully understand if you missed this) - 

My question was if you could advise if the test was a good way to gauge listening ability, but your reply involved "Methods for the subjective assessment of small impairments in audio systems", training and learning.

My question did not have anything to do with a method, or training, or audio systems, just whether the test, even if intended to have participants give a ‘no, there is no difference’ answer; only if you could advise if it was a good starting point to gauge ‘listening ability’.

The first response you gave me the impression you had already decided the test was not good for training or or learning. The test was certainly not posturing as being anything other than a simple measure if an individual could hear the differences of resolution in the two files presented.

It seems to me, with the results I got from the twelve friends I asked, that the test, however basic, served its purpose. I wondered if you could advise if this simple test works well enough as a beginning to determine good listeners from bad listeners, all training aside.

Thanks again, and I look forward to your reply! 

In friendship. - kevin

Fourier theory is not part of the design of any amplifier. Nor is Fourier theory what the paper is about that you keep posting

I never said a such non sensical thing about Fourier being part of the material design of an amplifier... They are the background theory for the hearing based frequency theory... i always spoke myself about hearing theory and the impact on design QUALITATIVE INTERPRETATION and the predictive relation between perceived "musicality" of the gear and some sets of LINEAR measures IN THE MASS MARKET INDUSTRY which are not enough to predict "musicality" of the gear because the human hearings work non linearly in the time dependant domain Simple.... I only said that some set of measures are interpretated in the LINEAR context with Fourier theory as a frequency based Hearing theory in the background interpretative context instead of a time dependant theory...By the way going in the time domain with your measures interpreted in a linear context, DOES NOT MEANS YOU WORK IN THE TIME DEPENDANT DOMAIN of hearing theory...The CRUX is not the time domain symmetricality in itself ( laws of nature can be read mathematically in a time independant way ) but it non symmetrical direction, then time dependant one, in a non linear way for human EARS/brain workings..

And again, much of our audio measurements is done in time domain with no usage of Fourier transforms. They are not bound by any uncertainty principal because they don’t attempt to quantify either time or frequency. When we use Fourier transforms, it is to decompose a signal, i.e. its distortion products. We don’t intend or rely on its frequency resolution.

All your measures being interpretated linearly OUT OF THE SPECIFICS NEEDS from a hearing theory based on what MAagnasco and Oppenheim and Van Maanen asked for, cannot have then any concluding value for interpreting them as "good sound" in a psycho-acoustic sense and i a predictive way... A good standard design dont means a "musical" pleasurable sound quality... You then really means only "good sound" as an attribution in a mass marketing standardized designing sense of the words... ... What you call "good sound" then with your set of measures has nothing to do with real "perceived sound qualities" in a psycho-acoustic SUBJECTIVE sense.... Then objectivists claiming the opposite are wrong...If anyone claim the opposite then it is because someone want to IMPOSE what must be a "good sound" with a hearing theory which is linear and TIME INDEPENDANT...

But now we have no debate TOGETHER you said it very clearly : Your set of measures cannot be claimed as to have any PREDICTIVE PERCEIVED SOUND QUALITY VALUES out of the numbers revealing some aspect of distortions and jitter, etc ...The fact that you equate it with good sound QUALITIES is purely an abuse of words; you means good standard design... Then Probability of a good sound with no predictive attribute .. As you say you LISTEN with behind your head the measures biases you had taken BUT you submit yourself to blind test...perfect then...

Then i had no more point of disagreement with you... It is the objectivists around you reading your reviews who EXTRAPOLATE and ATTACK subjectivism claiming to some "musicality" and grow in a cult using some specialized set of measures as PREDICTIVE instead of being only : minimal or optimal standards with no predictive value for "musicality"...Which quality is "unreal" or "illusory" anyway for them ......You are more "neutral" than this circle around you and you do a job thats all... And effectively you cannot be faulted for the rudeness and wrong interpretations of others.. yOu stay silent and give your reviews... Anybody can interpret your verdict as predictive of "good sound" or not... It is up to them... And up to a blind test... 😊

Thanks for the discussion... I learned a lot... i am not qualified in any way, i am not an engineer, but i know how to read... And Hans Van Maanen is more than qualified here... I read his very simple and very clear articles among others.....magnasco and Oppenheim experiments are after 60 years the culmination of a trend growing in hearing theories : Human hearing must be based on an Ecological theory of hearing as exist an ecological theory of visual perception by J. J. Gibson and based on the AFFORDANCES given by natural sound analyased in a non linear way in the time dependant domain by the ears/brain... I suppose you know this book :

wikipedia:

«James Jerome Gibson (/ˈɡɪbsən/; January 27, 1904 – December 11, 1979) was an American psychologist and is considered to be one of the most important contributors to the field of visual perception. Gibson challenged the idea that the nervous system actively constructs conscious visual perception, and instead promoted ecological psychology, in which the mind directly perceives environmental stimuli without additional cognitive construction or processing.^{[1 »}

he wrote one of the most influential book about visual perception research in the century...

All my observations about the non linear and time dependant dimension of hearings and their future impact on gear design must be interpreted in  this book context ... Van Maanen use this hearing theory to design his amplifiers ande speakers... This is the reason why i used it...

Then no i am not qualified, J. J. Gibson and Magnasco and Oppenheim and Van Maanen are qualified more than necessary...

Keep for yourself your theory that all there is to say about sound qualities is relative to your limited set of measures...

I don’t have to keep what I have not stated.

@manuelguerrahr 

I can’t believe I have not received one darn response.

...probably because you are posting on the wrong thread AND this is a discussion forum rather than a sales forum.
