Amir and Blind Testing

Actually- this thread was not about electronic measurements.  It was about Amir’s observation about the human brain and its ability to hear non-existent improvements when switching components because we start listening in an “analytical mode” when we are testing hifi equipment. Of course, Amir is not an expert in psycho acoustics, but I thought it was an interesting concept and many members related to it to some degree. The human sensory system is so easily fooled. Ever take one of those flight simulator rides at Disney?  Vibrate the seat, tilt it back and show us a video of flying and we swear we are traveling through space. A little scary how easily our senses can be deceived. What do we do with this knowledge?  Whatever you want, that’s what.

course, Amir is not an expert in psycho acoustics,

Fortunately there is an expert who graciously contributes his knowledge at ASR

What is measured? Sinad? Look up how useful sinad is and you will see that it is not that useful.

SINAD is useful but it's not the only thing measured. It seems to me the amount of half truths and downright nonsense posted here about ASR borders on paranoia. Perhaps it's because they are a growing presence and some feel threatened but after all it's just another website the deals with measurements and objective and to some degree subject aspects of high fidelity playback systems. You dont have to take everything presented there as gospel but with an open mind you might surprise yourself as to what you might learn. 

Thanks for the reference... Very interesting set of articles !

But i was talking about small room acoustic and psycho-acoustic of small room...

And it is a field in itself...

And if you read the site all is about psycho-acoustic and digital technology....

Almost anything about small room acoustic...

What matters for them, at least for Amirm are the tools to measure human hearing in sound PRODUCTION... Not about sound ACOUSTIC TRANSLATION in a small room...Signal processing is not room acoustic....

I dont suggest here that this prycho- acoustician who work with them know less than me... I am not an acoustician myself for sure... I only express my opinion about the emphasis put on DIGITAL TECH. and hearing abilities in the digital tech.context, not in the relation between physical acoustic and psycho-acoustic in small room , which is a field in itself...

My point is that ANY measures of the gear must be subordinated to the small room/ speakers relation and specific ears abilities and listening history of the owner of the room... Because CHOOSING a piece of gear at his peak working potential ask for the guiding listener/customer subjective impression in a room not only about some electronical measures of the gear...A point that NO ACOUSTICIAN can contradict by the way.... Even this one....

In a word what these articles spoke about centered around digital tech. EQUALIZATION, my own approach to room acoustic centered around more Primitive so to speak, Helmholtz MECHANICAL approach... I will read these articles because psycho-acoustic dont change his principles from the digital field to room acoustic...

But in digital tech. the focus is in the technology itself, in room acoustic the focus is around the owner of the small room... Some subjective impressions are  at the center of the matter here;  AFTER an objective disposition of the acoustic content of the room in relation with the specific abilities and limitations of the room owner...

Of course, Amir is not an expert in psycho acoustics,

In a word i dont need a blind test for any change in the acoustic disposition of my own room...

And the specs sheets of any piece of gear so important and useful it can be to pairing piece of gear with one another SAY NOTHING about the FINAL sound quality of the system as a whole and his relation to the specific room and to my SPECIFIC ears...

Simple no?

I reject the " brand name gear tasting subjective fetichist " and "the digital tech measuring tools objective fetichist " TOGETHER here , because i live and listen in my room acoustic and the two groups completely UNDERESTIMATED small room acoustic power....It is there in my own room that the gear succeed or fail FOR MY EARS , nevermind his measured specs...Correlation between the objective position,size, tuning of acoustic devices in my physical room and my own tuning subjective abilities and preferences are WHAT MATTER....

I called what i added to the classical passive materials room treatment, mechanical equalization and active tuning control of the room after Helmholtz method...

I dont design a product to be sell, i design my own room.... AT NO COST or almost... 😎 But i made it with a METHOD....

Why?

Because a SMALL room is not an amphiteater acoustic....One is designed by my ears for my ears, the other one is designed for a crowd... Timing of waves, pressure zones control distributions for example dont play the same game here...

Acoustic of the room is the sleeping princess, all pieces of gear are the 7 working dwarves with their tools , and psycho-acoustic of my own specific ears is the kissing prince....

A riddle:

Do you think i modified my speakers for example in reading only their specs sheets ? or by listening them in my room? I listened to them and used Helmholtz resonators and diffusers ON THEM also to crossfeed each one and decrease the acoustic crosstalk in my own way mechanically...Results are astonishing...In near listening and in regular listening...

Each one of our ear and singular speaker is a world in itself....
