No I don't think anyone would notice that. I was
thinking more about
the stereo imaging. I know at some frequencies the brain senses
direction of the sound by the phase difference from one ear to the
other. The last time I did speaker listening tests (10 years ago?),
I found very few that gave good imaging anyway (and they were not
the most pricy either). Maybe things have gotten better. Maybe usecs
of difference from one ear to the other are not noticable too.
One microsecond means 0.34 mm (1/75 inch) at the speed of sound,
or 0.12 degrees change of direction for a frontal sound source.
So you need 8 usecs to change the direction by one degree.
Maybe you could detect that if your head were clamped in a
vise. Test at your own risk :-)
