The invention of measurements and perception


This is going to be pretty airy-fairy. Sorry.

Let’s talk about how measurements get invented, and how this limits us.

One of the great works of engineering, science, and data is finding signals in the noise. What matters? Why? How much?

My background is in computer science, and a little in electrical engineering. So the question of what to measure to make systems (audio and computer) "better" is always on my mind.

What’s often missing in measurements is "pleasure" or "satisfaction."

I believe in math. I believe in statistics, but I also understand the limitations. That is, we can measure an attribute, like "interrupts per second" or "inflamatory markers" or Total Harmonic Distortion plus noise (THD+N)

However, measuring them, and understanding outcome and desirability are VERY different. Those companies who can do this excel at creating business value. For instance, like it or not, Bose and Harman excel (in their own ways) at finding this out. What some one will pay for, vs. how low a distortion figure is measured is VERY different.

What is my point?

Specs are good, I like specs, I like measurements, and they keep makers from cheating (more or less) but there must be a link between measurements and listener preferences before we can attribute desirability, listener preference, or economic viability.

What is that link? That link is you. That link is you listening in a chair, free of ideas like price, reviews or buzz. That link is you listening for no one but yourself and buying what you want to listen to the most.

I like to remind people that math is an excellent tool, but to remember that math exists no where in the known universe except as that - in a human’s head.

Likened to an extra long perfect kinda stick for getting the ants at the bottom of a deeper hole (on the Savannah) but, to remember that is all it is.

For example, math is not science, it is not a arbiter, even though it is a factor and an important one. But that it cannot stand in stead of logic and open minded analysis.

That we like to use numbers in analysis and would love to try to frame, corral, and label human desires. And thus own desires and perception as a tradable, saleable, storable, repeatable, fully known and owned commodity.

People have been trying to do this for thousands of years, and have pretty well gotten no where. But they sure have mastered the basics...(think modern media manipulation of the masses)

Then we want to quantity and commodify human hearing. That turns out to be a waste of time, as we don’t fully understand the limits of human perception, let alone that each and every one of us is different in such to the point that no perfection in such desires to quantify--can be found..

If we could only get one more decimal point of accuracy! Sorry dude, not happening....

As, in audio we talk limits of perception, not the basics. Basics, we all got them. Quantification can and does happen there, no disagreement from anoyne on those parts.

Limits is the deal...Peaks, absolute peaks... and there, it is all fuzzy and 100% individual in level. It’s like IQ tests..when you get beyond the basics with such testing, it gets less and less relevant and when reaching the most intelligent, IQ tests are useless. Absolutely useless.

One of those chicken and egg problems that not enough people understand the huge scope of it as existing. From those, you tend to get argument that audiophiles can’t hear what they say they do and here’s the numbers to prove that.

Where if one even begins to understand what I wrote about, it is not possible to be more incorrect than that position about extreme audio and those who hear things in it.

One could write a book on the subject and not make a single misstep. But the contrarian spitting vitriol would have to be open minded enough to not just read it, but to understand it. To be stable enough to be open.

Like Bruce Lee said, "Do not concentrate on the finger or you will miss all of the heavenly glory!" 

When science and math have a problem they can’t unravel, it (as a pair) can quite likely find itself being forced to ground to go to first principles, which are rooted in philosophy and logic. Philosophy being the actual parent of it all, in effect, or... Logic and the attempt to make logic provably, repeatedly - functional.

We won't get into engineering attempting to be to be the logic poseur that it is  when it tries to express itself in scientific exploration... this is due to the literal construction of engineering as a dogmatic form. Repeatability, is what that is about. Engineering has nothing to do with formal and actual science, engineering is a end point , in repeatability, of the application of proven science.

Thus, beware the engineering mindset that tries to dogmatically push numbers and book learning... into a frameworks and area of scientific exploration ....where all the realities are not even remotely known.

Like that of high end audio and human perception.
Not to be confrontational but math is not the same thing as measurement. And mathematical proof is not the same as scientific proof. Things can be proven mathematically and math can support scientific evidence but math cannot prove a scientific theory. Measurements are however evidence for scientific theories. For example, measuring the velocity of light. Or, in the case of the relativity theory, measuring the anomalous rate of precession of the perihelion of Mercury's orbit.
Sure thing Geoff, got it. No one is perfect.

I’m just rambling, looking for some projecting hornets nest to inflame itself and start poking at keyboards in anger. :p
Wow, That was what I call a quick response!  I was still composing. 😁 Don’t go poking hornets nests if you don’t want to get stung. 🐝
A musician with perfect pitch hearing can perceive  whether a tuning fork or oscilloscope is on pitch, or flat, or sharp. Like everything else, the measuring tool is not infallible.
