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.

Listening to music a "hobby"? Not for me; it’s at least as important as breathing, eating, or any other activity necessary to sustain life.
A separate issue, but very related: I knew a lot of musicians in High School who were very surprised by how difficult college-level music theory was to grasp. Music theory is on the same level of intellectual difficulty as both advanced mathematics and electrical engineering, sharing with both their completely objective truth and seemly-abstract principles. Abstract in the sense that, as Roger Modjeski (my "hero" ;-) put it, you can’t see electricity (or music). A circuit can be expressed in a schematic, however (and music can be notated). In his course on hi-fi design and engineering, Roger therefore uses analogies to help his students grasp the concepts of current, voltage, etc. (the rate of flow of water out of a tap, the water pressure, etc.).
