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.

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.
Good points.

I guess my focus is on the distance between a measurement, which could be done by an automated device, and human perception/value.

I agree we've measured jitter for a while, but was that all? Were there some kinds of jitter worse than others? How low before we can no longer tell?

If it weren't for math, you wouldn't have a head.

You appear to be worshipping at the wrong alter even the best math is not God or the Creator of Life you are a confused, disoriented, misinformed person.
Whoa! What is this - a convention of English majors?

In audio the most logical approach is to assume everything is true and nothing is true.
