They can certainly tell the difference if the left and right hand
channels are out of phase.

What do you mean by out of phase ?

Oh dear, dear, dear.

Are you saying that getting the speaker wires crossed is out of phase ?

Yep, if you do that with just one of the two speakers.

You do know that the human ear can;t detect phase don't you ,

It can with a pair of stereo speakers with one with the wires transposed.

The human ear is insensitive to a constant relative phase change in a
static waveform.

What you get on speakers aint a static waveform, stupid.

And humans can't detect phase, they can tell if something sounds distorted but that doesnl;t tell then what phase the signals are at.

the ear sure can tell when too sounds otherwise the same arrive in
antiphase qand cancel each other out.

but only if they are the same and cancel each other out, and that still relies on the amplitude rather than the phase.
That's hwo noise canceling works, it doesn;t mean there;s no noise, so how would yuo tell the differnce between two signals in anti-phase (inverted or 180) from a system that is off ?



Bass performance of a pair of stereo speakers is seriously ****ed if one
is in antiphase. Mind you with subwoofers these days the problem is less
noticeable.

but you still can't tell phase, what you hear is amplitude NOT phase.
