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.

 When folks with those claims are tested formally, they cannot repeat their outcomes.  

The problem is some audible effects are very very small but still important. These differences would not be detected with a traditional blind test. The knowledge that you are being tested would be enough to counteract your ability to hear the difference as it shifts your focus towards the test rather than the music. This is why the double blind tests are wrong. We would need MRI scans to really understand if certain effects are audible or not. If you do 2 seconds of jitter could you hear it? yes of course we can. But once you get down to the picosecond range, a traditional blind test will not be adequate. 

I’m fairly sure that @kenjit and @thespeakerdude are quite popular and active on ASR.

Alright guys, I’m sorry if I hurt his feelings (Amir).

This is an online forum where freedom of speech is allowed. If you disagree with what someone else posts, you certainly have a right to defend your own viewpoints or critique what others have posted. Picking apart little tidbits of what others have posted is not really a strong way to win an argument...I barely try to win, yet strong retorts from any so-called objective audiophiles are very, very, rare.

Reading what @milpai wrote above tells me he is a mature adult. Do you have some instrumentation to test that, or will you try and read what he wrote again to formulate a new response; using your good judgement and intellectual honesty?

@thespeakerdude ,

I have asked the the ASR admin about the brain interpreting the sound waves question and he has managed to dodge the question before. You can go and check the previous discussions from a different thread. When a person claims that "I know all that I have to know", that tells me that it is a "closed brain" which is not open to learn anything new. Search the 'Gon and you should see my interaction with him. Look - he is most likely an expert in measurements. But he is not above the scientific world which has yet to find the answers on why each human being intercept sound differently.

I think he dismisses folks who will not buy a piece of equipment once they evaluate with their ears and do not find differences with the current one. I don't want to pay my hard-earned money on something that makes no difference. Only if I find a difference will I be convinced to buy. And I don't need anyone telling me what I should like or not.
