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.

You know what guys, you're sounding very very old. Today is the last day of the CES 2019 and the young brains there have moved so far beyond this discussion and frankly Stereophile magazine’s view of technology it’s not even close. Stereophile in fact is so stuck it could only send one reporter to the show. They can’t even see that the paradigm has shifted and exploding with new innovations.

While some of you are debating (still) the perceptions of sound the world has walked right on by you and on to the next chapter (chapters). I guess that’s what happens when you are a part of a world pre-internet and pre advanced teaching and technology. Calling each other mentally ill while your arguments are obsolete and irrelevant as far as this generation goes I guess is insane. It’s at least reserved for the unaware.

There’s nothing wrong with playing in a world of aged information, old people do that. But when you think you have something to still teach this fast pace technology world your fooling yourselves. You guys are still playing with mu-metal and sorbothane while the modern world is designing products to work with fields not trying to kill them. When you kill a field you also remove part of the music signal. When you dampen you do the same thing. When you house your electronic parts in a heavy chassis, same thing. Your talking about problems that don’t even exist in modern technology.

My friend from Kansas said it very well "carry on my wayward son". Do you guys ever wonder why HEA shows are almost all old folks now? It’s not because the young have not figured it out yet.

Here is the CES website for those interested in what the CES has been and is today.

http://www.ces.tech/

And here is NAMM, which is usually about 10 or so days after CES.

http://www.namm.org/thenammshow/2019

The CES is the home show and NAMM the pro.

It looks as though High End Audio, because of it’s decline in numbers, won’t be featured in either of the two bigger shows. That’s not official but with HEA only having 28 display rooms this year at the CES the rumor is the more tech driven shows won’t likely be the home any more for High End Audio displaying. I hope that’s not the case because HEA without being able to piggy back on one of the bigger shows will loose even more exposure in the US.

"That's a very generous interpretation."

Very generous!

With the exception of some reviewing Stereophile sells ads. All magazines do. The discernment is up to the readers, but since the internet truth finding is easier. Stereophile only has so many rooms, setups, ears and review deadlines to judge with. Those who experience are the real tellers of audio and we don't find many of them posting because of trolling, but their experiences are what give us insight beyond our own.

I would say it takes about 6 months (again being generous) to see who the experienced guys are here, or on any forum. Once you spot those guys It's easier to get real (factual) opinions from. Even those I may differ with, reading their experiences is valuable.

I guess this is what old men do to still show themselves relevant (no fault of the OP, the topic was legitimate). The proof on this forum is staggering. Topics that have been covered and documented in the 70's make their way back into discussion as if it is something new.

I don't know about other readers here, but I recall learning about the color of frequencies two fold back in my photography and music theory classes. I question if some of these guys ever went to school, or even now with so many of them being Wiki-fied grads how they can turn these threads into two sided spin cycles for the sake of the spin only. I highly doubt anyone from outside these pages are interested in the intellect of the Agon aged. It is good entertainment on a lazy afternoon to cure boredom as Glupson would say, but really only a sign that these guys aren't listening to music as their main hobby.

Agon forum lifers, an interesting bunch of folks indeed.
