- Nelson Pass
Good post Erik, agree 100%
In Defense of Audiophiles, Bose, Pass, Toole and Science
This may look like a weird list, but here is what all these have in common: They strive to link together human perception and enjoyment of a product to measurements. Each have taken a decidedly different, but very successful approach. They’ve each asked the question differently. I don’t always agree with the resulting products, but I can’t deny that their approach is market based and scientific.
Floyd Toole’s writing on room tuning, frequency response and EQ combines exact measurements with human perception, and as big a scientist as he is he remains skeptical of measurements, and with good reasons.
The process Nelson Pass uses is exactly right. His hypothesis is that a certain type of distortion, along with other important qualities, are what make for a great sounding amp, and lets face it, the process, and his effectiveness cannot be denied as not being scientific or financially successful. Far more scientific than designing or buying an amp based on THD% at 1 watt alone.
Bose is also very very scientific, but they come at the problem differently. Their question is: What is the least expensive to manufacture product we can make given what most consumers actually want to hear?" Does it work? They have 8,000 employees and approximately $4B in sales per Forbes:

Honestly, I don’t know how your average Bose product would measure, but you don’t get to these numbers without science. Assuming they measure poorly, doesn’t that mean measurements are all wrong?
The work Harman has done in getting listening panels together, and trying out different prototypes while adhering to previous science is also noteworthy. Most notably and recently with their testing of speaker dispersion which has resulted in the tweeter wave guides in the latest Revel speakers. They move science forward with each experiment, and then put that out into their products.
Regardless of the camp you fall into, crusty old measurements, perception measurements or individual iconoclast, we also must account for person to person variability. It’s been shown for instance that most people have poor sensitivity to phase shifts in speakers (like me), but if you are THAT person who has severe sensitivity to it, then all those studies don’t mean a thing.
My point is, let’s not define science as being purely in the domain of an oscilloscope. Science is defined by those who push the boundaries forward, and add to our understanding of human perception as well as electron behavior through a semi-conductor and air pressure in a room. If it’s frozen in 40 year old measurements, it’s not science, it's the worship of a dead icon.

If I told you Karl-Anthony Towns is just as good as LeBron James because they both averaged the same number of points per game, would you buy that? What if I went further and said and perceived greatness of LeBron was simply snake oil that you dreamed up in your head? There has been a revolution in sports analytics in this century to the point where it is now very easy to show why LeBron was better than KAT in a number of different ways. The audio measurements crowd needs to similarly step up its game. Distortion and frequency response is points and rebounds. Points and rebounds are important, but Karl-Anthony Towns ain't leading you to a championship. |
cd, I didn't say anybody should study basketball stats, but I tell you what, let's trade. You send me the precise electrical measurements for midrange transparency, and I'll send you the NBA players who were the best this year at defending the pick & roll. Oh heck, I know you're not interested, but here they are anyway: https://stats.nba.com/players/ball-handler/#!?sort=SCORE_POSS_PCT&dir=-1&SeasonType=Regular%20Season&TypeGrouping=defensive The point of my analogy is if you were to ask for those stats 20 years ago you would've just gotten laughed at. Now they are at anyone's fingertips. Meanwhile in home audio, we're still looking at the same old measurements of frequency response and distortion and saying this is what something sounds like. As Erik said, that's not science. Precise or otherwise, that's the equivalent of heading to a sports analytics conference with a pack of baseball cards. |
