That's not 'detection of phase', that's detection of two tones of slightly
different frequencies.  It's not the same thing at all.  Two tones of
slightly different frequencies will create a 'beat' between them, which
will sound like the tones are quickly increasing and decreasing in
volume.  The 'phase' here is two tones of the _same_ frequency, but with 
one slightly leading or lagging the other.  Here I'd have to agree with
Matt, we can't detect that nearly as readily.
