Lightbulb Hearing versus physics and modern compression

Human hearing beats sound’s uncertainty limit, makes MP3s sound worse | Ars Technica

Interesting article about human hearing, perception, physics of, and why it might be time to revisit compression algorithms.

My take on it has been the same as a few other notables in the forums regarding hearing (in terms of distortion of SS versus tube distortion most notably) and why a scope, numbers from the scope, math, and numbers might not sound that pleasant to your ears.

Some will say, "whathas this got to do with speakers, tube amps, silicon, and cap banks?". This is beyond the article, but it is still along the same lines of what produced sound from your diy amp is pleasant to your ears.

Not owning a oscilloscope, I have no choice but to rely on my tin ears.

That research seems to be spawning a whole rash of ill-informed comment, both on here and linked from here. Not picking on you, but I think this is the third thread referring to that research. Fourier has not been disproved. The human ear does not violate any physical limit. All that has happened is that a rather over-simplistic model of hearing has been shown to be: guess what, over-simplistic!!

Now, shock, horror, someone thinks that MP3 might be less than perfect.
