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 must agree that the supposed aim of this whole site is what drives a person to like something, sometimes more than another option.
I taught statistics and experimental psychology... and nothing irks me more than someone who quotes chapter and verse about something which has to be experienced to be appreciated. As an EE, I designed test equipment, which was usually limited to 50 KHz in the specs. Much of the time, it was not the sound which was being measured, but noise patterns (atomic submarine prop noise, for example). The equipment was "state of the art" and cost more than most high end systems... yet, as an audio source for listening to music, would fail most miserably. Yup. Because it wasn't designed to PLEASE the user, just generate data for decision making. I must say your post was a breath of fresh air, Erik!
