What covid research can teach us about audio measurements.


Recent studies in Canada for patients with so-called long covid show us on how science and measurements and research actually works.

Patients with long covid suffering from limited ability to exercise passed most "normal" tests but it took a new type of test to positively identify a mechanism that explained why the patients suffered.

 

Honestly there is a lot of snake oil and charlatanism in our hobby, and I don't claim to discount that fact.  What I do want to say is that science doesn't rest with 50 year old measurements.  It evolves to measure and explain constantly. 

The reason I am personally dissatisfied with audio measurements in the common literature is exactly because of this stagnation, and when these fail us we trust our ears and gut for lack of better tools. 

Anyone who runs the same 20 measurements on an amplifier or DAC and claims it is science and that these measurements are all that can be known is fooling themselves into believing that they are scientists or that we have reached the limits of understanding.

And above all, caveat emptor!

Why do those who dismiss measurements in audio not realize that even gear designed without measurements is made up of parts that must be measured and must meet spec? Your hand-built loudspeakers are made of carefully designed and measured parts as are your amps and all things audio. You may not think that measurements matter but they sure as hell do when anything is constructed. Even the plywood and fasteners must meet well-measured specs. 

I do not think people are dismissing measurements wholesale. There are other influences or factors in audio. The ranges are more dynamic.

You can have carefully designed parts and measured parts that can sound awful together in execution. This is the case in any design and in general in engineering, this is why we validate, validate, validate. Design and build is objective, consumption is subjective, meaning there is more bias from the consumer or end user. 

What a dignified response.
Gone 3 days and here is this comment by noise in the Recent Activity.
Way to keep it classy! So if people disagree with your agenda they are mental defects? Should they be sent to camps? 

That's rich coming from someone I called out for making anti-Semitic remarks. Just look how he, ozzy and whitefish all group together. Fish in a barrel. Hey, that gives me an idea!

All the best,

How could you be sure that any audio product matched its prototype without measurements? Don't audiophiles look at measured specs when buying? Or do those who disregard measurements as having any useful meaning just buy on looks and costs? Pretty sure many of those who dismiss are looking closely at published specs when buying.
