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.

That was a perfectly respectable viewpoint until the work of Hilbert, Russell, Godel. The nature of mathematics is rather deeper than you suggest. As for it's relation to psycho-physics, or any other science done right, you might consult "Foundations of Measurement."

You’re being entirely arbitrary in your definition of what constitutes a measurement device. You seem to be hung up on intent. By that rationale a tree is not a measurement device, but to those who understand how information is encoded, it certainly can be. Climatologist routinely use tree’s growth ring as a record of past climate conditions.

The fact that we don’t have a comprehensive model (and accompanying measurements) of some of the finer points of audiophile oriented music reproduction, does not mean such a model cannot exist. You would really be hard pressed to come up with areas that are not capable of being studied via the scientific method. Possibly the single greatest achievement of humans is to understand that the physical world is systematically understandable.

Beings you introduced trees into this thread. Using a microphone and a recording device it can be proven a falling tree in a forrest will make a sound even if someone is not there to hear it.
Question is, how accurate is the recording of the sound of the tree falling and as it hits the ground? Can it be measured using other test equipment?
