Why HiFi Gear Measurements Are Misleading (yes ASR talking to you…)


About 25 years ago I was inside a large room with an A-frame ceiling and large skylights, during the Perseid Meteor Shower that happens every August. This one time was like no other, for two reasons: 1) There were large, red, fragmenting streaks multiple times a minute with illuminated smoke trails, and 2) I could hear them.

Yes, each meteor produced a sizzling sound, like the sound of a frying pan.

Amazed, I Googled this phenomena and found that many people reported hearing this same sizzling sound associated with meteors streaking across the sky. In response, scientists and astrophysicists said it was all in our heads. That, it was totally impossible. Why? Because of the distance between the meteor and the observer. Physics does not allow sound to travel fast enough to hear the sound at the same time that the meteor streaks across the sky. Case closed.

ASR would have agreed with this sound reasoning based in elementary science.

Fast forward a few decades. The scientists were wrong. Turns out, the sound was caused by radiation emitted by the meteors, traveling at the speed of light, and interacting with metallic objects near the observer, even if the observer is indoors. Producing a sizzling sound. This was actually recorded audibly by researchers along with the recording of the radiation. You can look this up easily and listen to the recordings.

Takeaway - trust your senses! Science doesn’t always measure the right things, in the right ways, to fully explain what we are sensing. Therefore your sensory input comes first. You can try to figure out the science later.

I’m not trying to start an argument or make people upset. Just sharing an experience that reinforces my personal way of thinking. Others of course are free to trust the science over their senses. I know this bothers some but I really couldn’t be bothered by that. The folks at ASR are smart people too.

Love this example. It doesn’t disprove what we might call the "objective" approach, but what it does is

(a) include sensory perception as a valid part of that approach and

(b) preclude over-confidence and overly-quick determinations by "objective" (i.e., mathematical, measured) approaches which judge too quickly what is "real" and what "in our heads."

Cable debates frequently go sour because of this division, but what’s clear to me is NOT that people don’t hear differences but that the differences heard are not yet measurable with the tools and/or metrics available. Skeptics like to call "placebo" on people who hear things, but not everyone who hears something is delusional.

This issue isn't unique to ASR. We have members here who insist that what you hear doesn't matter, and that they can determine how a component will sound based solely on its photo or spec sheet. Things get ugly quickly if you question their "logic."

If this post is aimed directly at ASR, how did it fly when you posted it over there?

I just asked how a component "sounds" over at ASR....... crickets.     They must pass on some great sounding gear , it's only about specs over there.
