How do we tell where a sound is coming from and what issues do hearing-impaired listeners have with finding the source of a sound?

I don't know if the brain has some kind of internal map for judging sound, but after my husband went completely deaf in only one ear from a virus, he has had a really hard time judging where sound comes from and often looks in the totally wrong direction when he hears a noise. In some ways its more frustrating than the over all decrease in volume. Anyway it certainly explains why we have two ears. Wonder what it would be like to have three or four. Lobsters sense vibration with their feet.

If everyone has different ear designs (I.e. ridges, folds and valleys) much like different finger prints or retina designs, then every brain's auditory function must match the outer ear, being a different program for each person by the billions. This is a feat that can only happen with a master Designer. I am a physicist that can only see the masterful hand of our Designer, his name being JHVH in the old Hebrew.
