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.

All of our sensory capabilities are not to be trusted. That is why our brain is so large...to better interpret what we sense. The foundation of science is proof and repeatability. Subjective experience is just that...subjective. Not proof of anything. Millions of people talk to their God everyday. Does not prove existence of a God. And there are so many other variables; cost, peer opinion, opponents' opinion, politics, origin, age, bias......

Discussion is valuable however, now what did I do with my blindfold? Must have misplaced it after my last duel.

You aren’t going to find many ASR lovers here. Most of us see him for what he is and move on.

Thanks for your insightful remarks. I really enjoyed reading them.

In particular, the anecdote about umami, and the various factors which enter into how we hear music (including circumstances and mood). Not only is it notoriously hard to describe what we're hearing at any given time, it's also quite difficult to control our attention so that when we listen a second (or third) time, we attend to the same particulars very closely. The mind wanders even when we try to stop it — and when we do try to stop it (e.g. fix it on, say, "that cymbal crash") we are effectively in a different state of mind (we're in a controlling state of mind, not a relaxed one).

This comment bears out for me, as well:

The most important element: quality of the original recording. Number 2: room acoustics. Number 3: speakers. After that, it’s all marginal effects. The debates about power cords, interconnects, even fuses is, well....

The way I understand the situation with many (not all) audiophiles is as follows: They're into the hobby. They want to hear changes and make improvements. But they cannot or will not listen to only well-recorded material (who can blame them) or deal with their room acoustics (practical obstacles or laziness). They also want to gear shop. So, in order to pursue the hobby, they have to exaggerate the differences made in what they can actually change. And that leads to debate of what (most will not admit) are marginal differences — compared to the ones which will really change things.

Each one of us is therefore unique. We simply will never perceive something, visual, auditory etc. the same way. That is why we cannot agree on "what's best" or what is the best method for determining "best".

I suppose the question becomes how we can ever agree on anything or even converse. My guess is that we are not only brains but creatures sharing a language and a culture. Thus, despite our manifold differences, we find ways to agree and disagree. 

@nyev 

Our subjective sensory experience IS flawed.

I know what you mean. I would use the word "fallible" and "subject to reconsideration when used as the basis for judgments."

Like you, I've made many mistakes in characterizing and evaluating what I was hearing. Talking to others and also just taking more time before judging has been the key for me. But your point is well taken.

 

Applaud legitimate scientific efforts and results.......to a point.  We need understand the world around us.  However, pick up any publication from any field of science, 50 years old, and study the practitioners' claims.  So much is so far afield it can be stunningly wrong.  Confirmation bias can afflict even the best of minds.

Practitioners of medicine used to perform frontal lobotomies in their offices.  Really? That alone should give one serious pause.
