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.

Interesting take. I’ve heard meteors as well (one over Tampa, FL around 1973 that was seen and heard by tens of thousands of people that night and I was at an outdoor concert - the meteor was LOUD).

But, yeah, “SCIENCE!” said…

NOW do a little online searching for validity of eyewitness accounts of accidents.

It’s really simple, right? Four people (count two of them - the drivers - as participant/observers too) witness a collision at a 4-way intersection.

Which story is correct? Police and claims adjusters and courtrooms are often employed to adjudicate these things because people’s memories are fungible things; what I see isn’t necessarily what you see based on your perspective and focus and abilities to recall what you saw (or think you did).

It’s been 60 years since JFK was assassinated, and eyewitnesses insisted on shots from other areas of Dealy Plaza and the grassy knoll and people are still arguing about it today. 

Basic measurements are only a benchmark, an objective standard, but how something SOUNDS is purely subjective and has to take into account intangibles like combined elements in the system, the room acoustics, speaker placement, and the listener, right?

A lot of this boils down to simple opinion, and everyone has one of those.

Amir does Amir, you do you.
