Directionality Explained

I believe that there are aspects of hearing that machines do not measure.

I think human hearing is just to complicated to be analyzed by just one or two numbers.  

Instruments cannot capture the entire event in any way approaching how we hear. They can only capture a pre determined aspect of a sound.

At the current time I am sure that we are not even asking the "correct" questions. And without those questions how do you measure? What do you measure? What scale is to be used?
Do we really ever use simply "one’, sense at a time? What about that pesky, "Sixth" sense?
How much of a role does "individual perception", play? 
Simply one’s mood can change any "perception". Hence how does that variable factor? 
And in how many ways? New scale?
On and on and on.
Let alone the design of any apparatus to help us measure, "quantify", in any meaningful way or even just to "qualify" in any way at all? Any result?
It Is therefore currently beyond our capabilities. But that shall not be true forever. It could be a relatively long wait though, "In case you happen to be in a hurried state".
Yet,
At least we are having this discussion. Which would never have taken place even a few decades before now. And "This", IS indeed part of the process!
No less important than any other part. "And quite possibly more important than many others".
Therefore;
Congratulations!

Your "involvement", in this thread, has moved "Human Understanding" forward.
By approximately "one", (standard), "iota"!
Shall we go for two?

I have to say it is a bit naive to think one can make some basic measurements of the cables and then trying to correlate that to human perception of music ... just saying.
