Your ears are very good.  Think about locating the direction
that sounds come from.  (Owl ears are not symmetric so they
get up-down information at different frequencies than the ones
used for right-left.)

To answer your question, the ballpark is 100 ms.  If something is
off by only 10 ms, that's equavilent to moving forward or back
10 feet.  You wouldn't notice that.

These are my opinions, not necessarily my employer's.  I hate spam.
