Then we use the same ...And i never ask anybody here to be believed to pass a public double blind test and not even a private simple blind test ... Guess why ? 😁
Double blind protocols may be applied with company sponsors or with costlier products ...
It make no sense for me in AN INCREMENTAL mostly acoustic process ...
What is simple with a cable had no sense in a room with a cheap homemade device change ... Simple blind test is enough in private ... Any advocating of Double blind test complex protocol AGAINST any audiophile claims value is preposterous and ideological ... I hope you see it ?
I dont need double blind test in official setting to test my cheap chinese modified Schumann generators location grid (each one on or off) and their ability to change my perception of sound ... Unvolontary blind test by accident and chance and voluntary blind tests were enough ... They happenned by forgotting to put some of them on or by conscious testing decision, then I did them and it work perfectly well ...
It c would be impossible to organize that in any other room anyway , especially as a public show for the sake of what objectivist call "science" at the singular which never exist in any other way than a belief ......( dont suggest to me cartoon comic objection as the way the earth is no more seen as stationary )...
Then i read many double blind test mandatory proposition as an ideological discussion about divided groups opinions about the efficiency of official or homemade products ...Because most of the times it will be a show , and a show impossible to entertain and organize anyway for the average guy as myself ...
Simple blind test informal work totally well and are enough for each one of us in private ...
The aural memory is not located in a specific place in the body or brain but is associated with multiple places and more than that on multiple levels and associated like a set of gestures to all the body and not only the separated brain and is associated to an acoustic context too where it work then optimally ... Then aural memory is more accessible in a routine habit in a very well known acoustic environment and in habitual relaxed circonstances ... Uprooting a listener is impeding the aural memory especially about debatable minute sound details separate meanings ...
But multiple simple private blind tests in the opposite to a public singular double blind test protocol test are in my experience necessary and impose themselves without any ideological need , simply by the nature and in the context of a cumulative incremental step by step process of optimization ... Those who urge in a strong manner about Double public blind test are not in an optimization process which asked for a very long duration in months and years as mine was and with hundred of changes , they are in an ideological crusade...
It is very easy to verify by the appeal of any "crusader" to "science" in the singular mode...i trust science only in the plural modes ...Not ideology ... Sound quality is a complex phenomenon which cannot be determined by double public blind test in any way, they for sure can be and had been used in official acoustic experiments context but a laqboratory is not a stage ... ... Not understanding that is not understanding what is sciences ... Simple private blind test are enough and done by almost everybody unvolontarily or not ...There is no real debate here only subjectivists against objectivists... I put my interest in acoustics with an s ...
I use single blind protocols for the majority of my shootouts. Works perfectly fine for their purpose.
