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.

What good does it if somebody tells others how a component sounds?

That’s for you to decide. Sometimes, as can happen with a movie or music critic, you find someone whose taste coincides with yours. That gives their opinion more weight. In audio for example, listeners may often independently conclude that a certain speaker tends to sound "bright," and that can be useful.

I need to hear it with my own ears and brain in order to make a judgement.

I agree completely, although I spell judgment differently. Of course, as has been shown in this thread, some dismiss those experiences completely. While that’s fine, it doesn’t obligate anyone here to submit to their demands for proof.

Looks like Amir is gone?

I doubt it. Wait for the next commercial blitzkrieg here shortly.

Besides, even if he is gone, it’s OK. Cin Dyment (aka The Speaker Dude nowadays) can handle the entire forum single handedly

I know the argument remains unresolved - are these things in my mind, or is it that science has not yet figured out how to measure certain things that we perceive in audio?

We can't measure what you perceive.  You listen to a track that brings you joy.  We can't measure joy.  What we can measure is the sound coming out of your audio gear.  That is the sound that is "heard."  What is perceived includes many other variables that go beyond sound. I enjoy watching my Reel to Reel play music.  It brings me joy.  But that has nothing to do with the sound.  The sound is excellent but I hear background noise which is not so nice -- something we absolutely measure.

Put more strongly, you have to identify what is sound and only sound in your perception.  You can't look at something, and give an opinion because your knowledge of what you are seeing pollutes your perception.  A person not likely horns will dislike any horn speaker.  Put them in a blind test though, and they won't bring such preconception to the party.  To wit, I was shocked how good these JBL horn speakers sounded in double blind tests at Harman that I took:

So bottom line, bring us an experiment where only the sound is evaluated and shown to not be random outcome and I will show you a measurement for it.  The moment you include other things, we can't measure it due to no fault of science, measurements or engineering.

And oh, there is no science being developed to determine what you state.  The science is completely settled that only results of controlled audio tests matter. where only your ear is involved.  All else is not worth even looking at.
