Interesting article. Yes, measurement tools have their place. In the end though, if "eyes and ears don't agree," we _must_ go with _ears_, in my humble estimation. Calibration is extremely important, BUT... It is all very subjective, because after all, we don't really listen to test tones, white noise, pink noise, or stereo glits, do we? We listen to music (and occasionally other program audio), and music listening is subjective (as is the "TV color perception" in the author's example). As the chosen sound/music professional, it is my job to _be_ the "arbitrary subjective measurement system." If my ears do not account for the lion's share of the gig/my being on the gig, than I might as well rent them a system and an iPod and let them have a go at it themselves. But if I'm hired as the DJ, sound engineer, or installation tech, it's _my_ ears that count (that's the whole point). I have seen faaarrr too many sound men that "mix by the numbers," and I haven't heard one that sounded good yet. If you only look at the meters and never listen to what you're doing or look up to engage the artist or the crowd, you may as well go home.
