Headphones

while listening music through a head phone many may have noticed that sometimes a particular sound may appear to come from the centre of the head and sometimes from both of your ears simultaneously ...

Howz that ?? I suppose that if the electric signal comes to both of the speakers in the head phone in phase, the music will appear to come from the centre of your head.and if there is a phase shift (multiples of

360degrees)between the signals then the sound will appear to come from the ears simultaneously..

Is that true ??

I read in sci.electronics.design that snipped-for-privacy@rediffmail.com wrote (in ) about 'Headphones', on Sun, 20 Feb 2005:

Not multiples of 360 degrees, which are equivalent to no phase-shift at all (but maybe a time delay) but 180 degrees. Strictly, it's *inversion* of the signal; phase doesn't really have a definite meaning with complex signals, only with sine waves.
