"One need only measure typical home hifi loudspeakers at the listening position to see how much our brain can overlook too. It is not uncommon to see what was a flat measuring loudspeaker measure + - 10 or even 20dB at the listening position. We hear through all that transmogrification but on the other hand, those are also the flaws which stop us from suspension of disbelief and reach the point where it really does sound like "somewhere else" like the original event."

Yes, that's true, but nevertheless psychoacoustic research shows that people can distinguish speakers with +/- 2 db difference depending on the width and location of the frequency change.

So even though listening rooms may cause such large changes, it doesn't meant that there is a big leeway in transducers.

It's like color perception somewhat. The brain corrects for external illumination in perception. You can have two patches of different colored paint in two rooms and then equalize the ambient lighting in one room so that technically the frequency response appears identical. And nevertheless all people will see them as being colored differently---meaning that the brain figures out the reflective properties of the intrinsic object (the paint) correcting for the environment.

That's just the point, we must advance beyond the current electromechanical loudspeaker technologies. - cfb 11:05:59 07/01/12 (1)
