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!

Audio measurements are becoming increasingly important as the success of sites like Audio Science Review indicate.

Never in the history of audio has the industry has moved in the direction of less data required.

The equipment and measurements being carried out today were simply beyond the reach of anyone outside of a prestigious physics lab 50 years ago.

 

 

 

What Covid research told us, of course is anyone's guess.

Suffice to say it took an enormous amount of political pressure to get Pfizer to cough up the truth about their Coof jabs.


I would expect more data to follow in due course.

Or, given the stance of the much of the media today, is the correct term "to be leaked?"

Pfizer Covid vaccine has 1,291 side effects reveals official documents by RT Staff Reporters - March 7, 2022

 

This release of documents follows U.S. District Judge Mark T. Pittman’s decision on January 6 to deny the request from the FDA to suppress the data for the next 75 years, which the agency claimed was necessary, in part, because of its “limited resources.”

For the record, I've never reported anyone.  And I never will. I said what I said above because I predicted this thread would go away based on the high level of hostility in some of the postings.  I've had complete threads and replies removed for absolutely no viable reason, which most of you I'm sure have experienced.  Why completely caustic threads/replies don't get deleted is a mystery to me.  No biggie.   Let it ride. 

Good designs will generate the same data, whether DACs, speakers or amplifiers. It's boring because a lot of gear is competently designed, and why it looks repetitive.

If you hook up a computer to two different cars, can the data tell you which car is quieter? More comfortable? Faster? No. What it tells you is that the cars are engineered correctly and you can expect consistent use for a long period of time.  That's how I look at measurement data in audio equipment.
