Apparently human ears can't detect the differnt phase so it shouldn;t make a differnce.

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 ?

When the cone on the left is pushing, the one on the right is pulling.
Then the brain might decide the sound is coming from behind you.

what brain?

Someone with a brain, could, given the chance to work it out would know that what they are detecting is amplitude NOT phase when this occurs, this is how noise cancelling works it takes the unwanted signal inverts it (puts it out of phase) and adds.

or yuo coulkd tell me exactly what happens when you hear two signals out of phase by 180 deg, what tells you how far out of phase they are ?

Can you tell 180 from 90, from 135, I dout it as human brains can't all they can detect is amplitude or volume.

You can detect differncies but only in volume/amplitude you can NOT dertect what phase they are at.

No need to say woosh with you, it's pinned to your jacket.
